Ctenophores are distinguished from all other animals by having colloblasts, which are sticky and adhere to prey, although a few ctenophore species lack them. |
A ctenophore does not automatically try to keep the statolith resting equally on all the balancers. |
Instead he found that various cydippid families were more similar to members of other ctenophore orders than to other cydippids. |
Some jellyfish and turtles eat large quantities of ctenophores, and jellyfish may temporarily wipe out ctenophore populations. |
But more and more evidence has since piled up in support of that view, including the first complete ctenophore genomes. |
For example, if a ctenophore with trailing tentacles captures prey, it will often put some comb rows into reverse, spinning the mouth towards the prey. |
