Nomura Jellyfish Hydra Coral Anemones Jellyfish.
Have tentacles with nematocysts near mouth. Nematocysts are stinging cells Cnidaria is Greek for “stinging cell” Examples: jellyfish, sea anemone,
Otherwise known as “Cool Coral and Friends!”. Common Characteristics ◦ Live in water ◦ Stinging cells (nematocysts) to capture prey and defend themselves.

Sponges and Cnidarians Animals unit. Mostly live in oceans, but also in freshwater rivers and lakes Adult sponges are attached to hard surfaces underwater.
Characteristics of Animals
Today’s Objectives: 3.4 Describe characteristics of this phylum
Phylum Cnidaria. General Characteristics They are radially symmetrical They have 2 tissue layers: Epidermis - Outer layer of cells Gastrodermis Inner.
Sponges - Origin of Sponges Fossil evidence shows that sponges appeared on Earth about 600 million years ago. Many scientists have concluded that sponges.
