In honor of our invertebrate lab and exploration of the animal kingdom, I’d like to invite you to hunt for some interesting invertebrate videos on the web.  I could really use videos for the following phyla:

  • Nematoda
  • Platyhelminthes
  • Annelida
  • Mollusca

But, any phylum will do.  Post a link to the video here and include in your comment information about the video, what phylum the organism in the video belongs to, and defining characteristics about the organism that determines its classification into that phylum.  Have fun!

    I found a video of a killer sea anemone eating a crab. A Sea anemone is in the Cnidaria phylum and is classified into it because of its tentacles. This was an interesting video because I have never seen a sea Anemone as big as this one. Sea Anemones are very clever animals and have a lot of patience when trying to capture other animals. Also a sea anemone has a gastrovascular cavity which means that it eats by its mouth and releases waste out of its mouth.

    I became amazed by flatworms after doing some searching on youtube, and I found these three crazy videos.
    http://www.youtube.com/watch?v=o1m0EWnQr1U
    After some looking around, it seems this giant flatworm feeds on clams and other small molluska.
    http://www.youtube.com/watch?v=HekwSO6dBG0
    This was the coolest looking flatworm I found. I looked around for the same species of flatworm, but this is what I found. It may not be the same species, but it was the closest out there I could find. Can anyone vertify this?

    And lastly
    http://www.youtube.com/watch?v=ET1v9-65Jwk
    This flatworm (what seems to be a spotted black flatworm) is a real swimmer. Not all flatworms are built to swim, but this one definately seems to be.

    This is a video of a unique squid that’s called a Vampyroteuthis infernalis or commonly known as the Vampire Squid. It belongs in the Mollusca phylum group because it has a soft body, a mantel, and the structure of a nervous system. The Vampire Squid has very large eyes that make it able to see at large distances. It also has eight long arms and a long strand that is used as sensor. What makes this animal unique from other squid is its ability to react when it is startled. This is what is demonstrated in the video. The Vampire Squid curls its arms and web around its body that it makes it turn almost “inside-out”. This change in appearance make the animal protected against its prey.

  • Ms Baker

    Jack, great videos! But, you need to tell everyone what phylum flatworms belong to in order to get credit for your comment. Thanks!

    Everyone, please read the full instructions above. Rohit and Adam did a great job with their comments.

    I think this is a great video of the phylum mollusca. In this video it shows a close picture of a snail moving. It is a mollusk because it has a mantle ,that in this case formed into a shell and it has a foot on the bottom of it that helps it to move. There may not be much going on , but it shows a snail in its natural habitat and it shows it doing something completely natural.

  • phoenixia

    This is a great video of flatworms, which belongs to the phylum of platyhelminthes ,because it shows the beauty of the flatworm in its natural environment. In the video, it shows many species of flatworms swimming in their natural environment. These are flatworms because their bodies are flattened and all of them are mobile. In this case, these flatworms are not parasites, but some can be.

    http://www.youtube.com/watch?v=EURfcsJEM8E

    I also found a video of pork tapeworms , which are also part of the phylum platyhelminthes because they are also flat and mobile. Showing the pork tapeworm, this video shows the flatworm as a parasite and the effects it can have on humans and pigs.

    I thought this video of green sea turtle and a loggerhead sea turtle, which both belong to the chordata phylum, and a tiger shark, which belongs to the chordata phylum as well, would be interesting to see how loggerhead turtles are killed more often than green turtles. Researchers can up with a new technological device to see and record why they came to this reasoning called the critter cam. For those of you who don’t know what a critter cam is it’s a camera safely put on the animal’s, well in this case attached to the turtle’s back. It captures video, sounds, and other information enabling researchers to see rare views of animals. By doing this researchers can to conclude that loggerhead turtles go to the surface more, making it easier for the tiger shark to spot their prey. Green turtles stay on the bottom surface more, increasing their chances on survival. Here is the link to the video: http://www.youtube.com/watch?v=Q_D51Ui_XMI.

  • Jack

    Ahh, I was almost sure I put in the phylum of flatworms… Well, all of these flatworms (and flatworms in general) are in the phylum platyhelminthes

  • Mike S

    Siphonophores are a type of jellyfish which is in the Cnidaria phylum. Siphonophores, also known as colonial jellies, can grow over 33 feet long. To get food, they drift around and catch food. To attract their prey they use their bioluminescent tentacles as a lure. Siphonophores are also the only know marine invertebrate to have a red lighted lure. They eat small copepods.
    They are a very interesting animal and, unknowingly, help feed another amazing creature. This creature is the barreleye fish. This fish lives around the same depth as the siphonophores. The barreleye fish swims through the tentacles of the siphonophore and eat the captured prey of the siphonophores.
    “The researchers speculate that barreleyes may maneuver carefully among the siphonophore’s tentacles, picking off the captured organisms. The fish’s eyes would rotate to help the fish keep its [eyes on its prey] while its transparent shield would protect the fish’s eyes from the siphonophore’s stinging cells.”-This is a quote from:http://www.mbari.org/news/news_releases/2009/barreleye/barreleye.html

    I found a really cool video of a giant octapus in freezing waters. Octapus are in the phylum mollusca. Unlike most mollusks they do not have a shell, but do have a mantle, the first steps in formin a shell.

    This is a video of horseshoe crab mating, development, and their life. The horseshoe crab belongs to the Phylum Arthropoda. The females are larger than males. The males attach themselves to the male to mate. When young horseshoe crabs are young they are shown to be extremely small.

    This is a video from national geographic that combines a few different phylums into one video. All of these animals are found in Suruga bay 70 miles southwest of Tokyo, Japan. One animal that is shown is the giant spider crab, which is the largets crab in the world. This belongs to the arthropoda phylum. The reason it is in this phylum is because it is a crustaceon, it has a segmented body which is one of the characteristics of an arthropoda, and it has an exoskeleton. In this video, coral is pictured multiple times. Coral is a part of the cnidoria phylum. It is a part of this phylum becuase it has tentacles with stinging cells in them. Also, all animals in the cnidaria phylum have radial symetry.

  • victor

    This is a cool vidio on the annelida phylum. This is a vidio of a clamworm. This vidio is great because it shows how a clamworm has a hole which is used to let out it’s waist and a seprate hole to eat. http://www.youtube.com/watch?v=LdHzRNdz2HU&NR=1&feature=fvwp

  • Justin

    The phylum Annelida consist of segmented worms such as earthworms, ragworms and leeches.Leeches are segmented into 34 parts and have 3 jaws.Most leeches are blood sucking parasites that feed on the blood of humans and other mammals. Humans for over 2000 years have been used for human ailment. In the video below the man has sarayasis and the doctor places leeches on the wounds.

  • Carl

    I found three interesting videos about annelids. In the first video, a National Geographic narrator explains how a doctor uses leeches to cure illnesses in his patients. He believes that the leeches suck out all of the impurities from the blood; and later, uses a substance to induce vomiting so the leech won’t digest those impurities.
    http://www.youtube.com/watch?v=cePKpt5nOJ0

    In the second video I found, a man explains how he saw a leech trying to eat an earthworm in the Southern Alps in Japan. In the video you can see the segments on the leech and the earthworm.
    http://www.youtube.com/watch?v=vpv9P1KOVMQ

    In the final video, an Australian tour guide is explaining how the leech feeds on a human and what it does to make its presence a secret. He also explains how the leech is able to feed for such a long time.

  • Carl

    I found an interesting video of a Nematoda; in this case, parasitic roundworms. This video was taken from the inside of a cat’s intestine. It shows many ringworms feeding off of the cat and living inside of it.

    This is a video of sponge reproduction. Sponges are in the phylum porifera. Sponges have no definite symmetry. Their body is multicellular, with few tissues, and no organs. Cells and tissues surround a water filled space but there is no true body cavity. All are sessile. They reproduce sexually or asexually, sexual reproduction can be either gonochoristic or hermaphroditic. They have no nervous system. Has a distinct larval stage which is planktonic. Lives in aquatic environments, mostly marine. All are filter feeders. Often have a skeleton of spicules.

    Awesome videos everyone!!!! My video is an example of the intelligence of the octopus. An octopus is shown here in an unprecedented example of “tool use” in which an octopus takes a coconut shell and assembles it into a shelter. The octopus is a member of the phylum mollusca and is one of the smartest invertebrates in the world!!!!

    Really cool videos! I found these videos of a razor clams being being caught. Razor clams belong to the phylum Mollusca. THey are caught during low tides when their holes are visible. Razor clams feature the common characteristics of the Mollusca phylum. They have a ‘foot’ and a mantle, is bilaterally symmetrical, and has a full digestive system.

    This video is of a flatworm from the phylum Platyhelminthes. The exact species is not known.
    [ http://www.youtube.com/watch?v=S6fJdgueHRk&feature=related ]
    Here is another video of some microscopic organisms. The ones in the video are: Euglena spirogyra, Holosticha, Vorticella and Bdelloid Rotifer from the phylum, Habrotrocha, Epistylis which is a Protozoa, and a Stenostomum which is in the phylum, Platyhelminthes.

    This website has a lot of great info on flatworms but it is in different language so if you are planning to look at it then you will have to translate it.

  • Alex

    This is a really amazing video of a flatworm swimming. After this short video, I recommend watching the entire series, they’ll automatically play after one another. Towards the end of the video, you can really see the almost translucent affect on the it has next to the sand.

    This is an amazing video of a mollusk octopus also known as the Grimpotheuthis.
    This octopus uses its fins to swim and “hover” in the water. They can grow up to 20 centimeters and live at depths of about 300-400 meters.

  • Geoffrey

    Awesome videos everyone! This is a video of a giant octopus getting extremely close to a group of exploring scientists. The octopus is part of the phylum mollusca and, as you can see in this video, can grow to gigantic sizes. It is amazing how fearless these animals are and how huge they can grow to.

    This is a video of an Octopus fighting another Octopus. An Octopus is in the phylum Mullusca, an Octopus is not to be underestimated. its ability to camouflage, its inteligence levels and the strength in its tentacles make it an ideal preditor.http://www.youtube.com/watch?v=hjGbKwOIw7s

    I found this link on Youtube. This interesting video gives some information on the Phyla that we have been learning about in our biology class. It also talks specifically about the class each animal is apart of. The first two minutes of the video talks about the Phylum Cnidaria. Animals like Jelly Fish and Coral belong to this Phylum. This video gives a lot of characteristics of theses animals, for example all Cnidarians have Bilateral Symmetry. Two minutes into this video it talks about Annelida. Animals like Segmented Worms (Earth Worms) or Leeches belong to this Phylum. The video shows a live Annelida under a microscope, you can really see how this worm is segmented. At 2:45 it introduces Phylum Mollusca. This very diverse Phylum contains animals like Snails, Clams, Squid Octopi, Slugs, and Oysters. There are also interesting characteristics listed, like how they have a muscular foot, Centidium (gills), a Calcareous Shell, and more. Next is Phylum Arthropoda (4:26). Animals like Ticks, Spiders, Insects, Crabs, etc. Every Arthropod has an exoskeleton. At 6:00 it goes in detail about Phylum Echinodermata. Animals like Star Fish Sea Urchins, and Sea Cucumbers are apart of this phylum. Lastly 8:17 into the video it talks about Chordata, which are animals like Frogs, or Turtles.

    This is a cool video about roundworms. Roundworms belong to the phylum nematoda. Roundworms are parsitic animals that claim the bodies of other animals. This video shows a rounddworm called W.bancrofti which took over this mans body causing him severe ilness.

    It’s interesting to see how certain species react to each other, especially in the mollusca phylum, as it contains some of the most intellegent species on earth. Octopuses and Cuttlefish are some of my favorite. As for their intellegence, just think of any of the species of the mimic octopus, who observe their surroundings and mimic them for protection. For cuttlefish, image how many cells their brain has to control to allow them to change color and paterns so quickly.

    This video is an introduction to jellyfish and their ways. Jellyfish are from the phylum Cnidaria. This means that they have stinging cells. They are simple animals, meaning they don’t have many organs or organelles. Most are carnivorous and others filter feed. Also some are capable of reproducing asexually as well as a sexually. When they reproduce the beginning stage is usually a polyp.
    This video shows a Irukandji jellyfish, one of the most deadly jellyfish in the world. They are box jellyfish., meaning they have the ability to propel themselves through water and they have a box shape called a bell.

  • Justin

    I found this extremely cool video of a marine animal called the cuttlefish. They belong to the phylum mollusca and are said to be one of the smartest invertabrates.Cuttlefish like octopus’s are masters at the art of camafloage.As shown in the first video when other fish approach the cuttlefish camafloages to the color of its soroundings.

    This is a video of a sea anenome eating a fish. The sea anemome belongs to the phylum Cnideria. It features the common charecteristics of Cnideria. It is sessial and has stinging tentacles. The tentacles are only poisoness to some fish. Clown fish are not affected by the tentacles and use them for protection.

    I found a very cool video on giant squids of the mollusca phylum. This video not only shows different parts of a squid, such as its fatal beak, but also its behavior, and how they are quickly spreading throughout South America. This video also explains their goals, one to eat and the other to reproduce. Here is the link to this awesome video http://www.youtube.com/watch?v=AQKs1-fwTgU

  • Joseph

    This is a video on sea horses doing their mating dance. This is really cool because I have never seen a sea horse before, let alone a sea horse mating dance. Sea horses are in the phylum Chordata. Chordates (phylum Chordata) are animals which are either vertebrates or one of several closely related invertebrates. They are united by having, for at least some period of their life cycle, a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail. We (humans) are in the phylum Chordata, along with fish, birds and amphibians.
    This is the video: http://www.youtube.com/watch?v=fcett5sPx_0&feature=related

    I found this really cool video of flat worms mating. Flat worms belong to the phylum platyhelminthes. When flatworms perform their courtship rituals it is almost as if they are attacking each other.

  • https://blogs.utexas.edu/pl6465/ peterlilsl

    I love sea-living things.I found a Chambered Nautilus video on youtube.They should belong to Mollusca.
    The animal has more primitive eyes than some other cephalopods; the eye has no lens and thus is comparable to a pinhole camera. The animal has about 90 tentacles with no suckers, which is also different from other cephalopods.

    Have a look!:)
