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!:)

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.

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.

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

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 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 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.

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 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.
