- Comb jellies are planktonic predators and are prey to fish, sea turtles, crustaceans, other ctenophores, and are even eaten by humans
- Comb jellies can be sensitive to water quality, so their presence in the Hudson River is a good sign
- Comb jellies get their name from their eight rows of plates made of fused cilia (little hairs) that they use to move through the water, which look like combs
- Unlike their close relative, the jellyfish, comb jellies do not have stinging tentacles and are harmless to humans
