Ctenophores are marine animals that possess eight rows of cilia that they use in locomotion.
Light scatters off these rows of cilia, often causing a "rainbow-effect" to radiate from ctenophores.
Although this phenomena is not actually bioluminesence, most ctenophores are bioluminescent
in addition to emitting the rainbow of light.
Ctenophores are carnivores that feed mostly on zooplankton,
with a few larger species feeding on invertebrate larvae and small crustaceans.
They use tentacles with specialized sticky cells to capture their prey and bring it to the mouth.
It is in this manner that ctenophores are capable of wiping out entire
ecosystems because of their carnivorous ways.
As voracious predators, ctenophores are capable of overpopulating ecosystems,
ravaging the food supply, and thus wiping out indigenous species of the area.
All ctenophores are hermaphroditic, releasing both eggs and sperm into the water as they swim.
The sperm find the eggs in the water, and fertilization then takes place.
