How Do They Eat?
Stingers eat small animals and plants, including fish eggs, worms, insect larvae, and even other stingers. Some eat larger animals, such as fish. Most stingers capture prey by injecting venom from stinging cells in their tentacles.
Stingers are very effective predators because they have the ability to feed continuously (although some feed only during either the day or night). Their tentacles function independently of each other, and they cover a large surface area to make it easier to capture prey. They get the oxygen they need for digestion directly through the water around them. Stingers do not have anuses; they discharge waste through their mouths. |
