This ctenophore, or comb jelly, is gelatinous like a jellyfish, but it’s in an entirely different family of animals. Some ctenophores have a non-stinging tentacles that, instead, release a sticky glue. But this comb jellies is in a group without tentacles (the beroid ctenophores). Instead, they have mouths that snap tightly shut — and they mainly use them to feed upon other comb jellies.
