Interesting Simple Animal Phyla

PLATYHELMINTHES : FLATWORMS 

Pseudoceros pardalis, or the leopard flatworm (in the video) is one of the most colorful and extraordinarily diverse marine flatworms.

I chose  to do the flatworms because I am both astonished by their beauty while being a bit grossed out with the fact that they are still classified as worms. I found out that they live in coral reefs, hidden under rocks or rubble. It swims using the edges of its body which are also the layers of muscle. As you can see, it is a very flat creature hence the name flatworm. They have very small hairlike cilia that cover their body to help them glide the ocean floor. They do not have eyes, but they can sense light.The interesting thing is that these flatworms don't really have a predator to watch out for, but are actually predators themselves. They feed off of injured animals, dead animals, bryozoans and soft corals. They can also absorb nutrients through the skin. 
Fun Fact: the female leopard flatworm is attracted most to the males with the biggest spots.
