No bones. No brains. But what a sting!!!! JELLYFISH

Habitat Jellyfish are found in every ocean. They live in both deep and shallow coastal waters. Also they can live in very cold or in very hot water. A jellyfish is a creature that lives in ocean. Some of them are big and some of them are small. And there are different kinds of them too.

Feeding Jellyfish eat tiny plankton, invertebrates, larvae, and small fish. Jellyfish have sensors in their tentacles that can detect movement around them. When movement is detected, stingers shoot out and paralyze the prey. The jellyfish then uses its tentacles to bring the prey to its mouth and ingest it. Jellyfish hunt for food all day.

Movement Jellyfish usually drift or move gracefully through the ocean, occasionally you will see them swimming. Jellyfish swim by pulsations of their umbrella or bell shape. It is coordinated by a very simple nervous system.

Appearance  Jellyfish often appear clear or pale blue color. But they can also be yellow, deep blue, bright purple, pale lilac, bright orange, deep red, green or be transparent. When they are disturbed at night, they give off a cold bright light called luminescence.
