Zooplankton and Epipelagic layer

For Zooplankton, the creature I plan to study are Jellyfish! Jellyfish are memeber of the phylum Cnidaria. Jellyfish contain elementary nevous system which detect odor, light, and other senses. Jellyfish come in all shapes and sizes and could be found in shallow and deep waters.

Epipelagic Open Ocean is the top layer of ocean zones which contain most of the ocean life. This is the only zone that contains plants because of the light which is needed for photosynthesis. This layer of the ocean contains Jellyfish, sea lions, sea turtles, sting rays, and many more.
