Cnidaria Report
Digestive System:
Cnidarians have tentacles, which help them to capture their prey efficiently by making use of paralyzing coiled stingers called nematocysts. These nematocysts are located within the cnidocytes from which their name is derived. The tentacles are then used to draw the cnidarians prey into their mouths. Next, enzymes located within the gastrovacular cavity are used to break up the prey. Certain specialized cells, which line the gastrovacular cavity, then absorb the nutrients.
