Phylum Cnidaria The Facts … Body symmetry- Radial Reproduction- Asexually and Sexually Movement- Polyps- Stationary Medusas- movement varies Food- carnivores- sting their prey

HYDRA Chlorohydra viridissima Hydra live in FRESHWATER. They are the only Cnidarians not to live in salt water. I’m hungry! Where is my DAPHNIA? This hydra is in its’ POLYP stage. DAPHNIA – are small crustaceans (like shrimp)

TWO BODY PLANS Medusa FREE SWIMMING Polyp STATIONARY

CNIDOCYTES – OUCH! That stings! Members of this phylum all have stinging cells to capture their prey and defend themselves called…. Cnidocytes Cnidarians can move in very interesting ways Hydra Jellyfish Anemones

Just how fast is a cnidocyte? …. Can you beat it? The average reaction time for a cnidoctye to eject a barb is about 700 nanoseconds!! .0000007 seconds One nanosecond = one second divided by one million!!! .0000007. seconds

The coral reef is made up of mostly Cnidarians and Poriferans. Nemo on his way to school

Cnidarians have a TWO WAY digestive system How do Cnidarian eat? Use the CNIDOCYTES in the tentacles to stun and capture prey. Tentacles pull prey to mouth and into body cavity. Prey is digested in body cavity using enzymes Whatever is not digested is spit out of the mouth. (ewwww…they eat and excrete out the same hole) Cnidarians have a TWO WAY digestive system
