| 11. | Biradial symmetry is a combination of radial and bilateral symmetry, as in the Ctenophores.
|
| 12. | The jellyfish themselves feed mostly on zooplankton, small fish, ctenophores, and moon jellies.
|
| 13. | Life Cycle : Ctenophores reproduce sexually.
|
| 14. | Pelagic species target prey they are capable of overtaking, namely slow-moving jellyfish and ctenophores.
|
| 15. | Hyperiid amphipods invade other jellies too, burrowing into medusas, for instance, as well as into ctenophores.
|
| 16. | After the fertilized eggs have divided twice, the ctenophore's later body symmetry has already been set.
|
| 17. | In fact, ctenophores have more distinct types of ionotropic glutamate receptors than any other known type of animal.
|
| 18. | Some predators include other members of gelatinous zooplankton such as " Beroe " ctenophores and various Scyphozoa ( jellyfish ).
|
| 19. | Adults likely feed on medusae, siphonophores, ctenophores, and salps, as well as some fishes, crustaceans, and molluscs.
|
| 20. | These statocysts are thought to be balance and acceleration sensors, as that is the function they perform in cnidarian medusae and in ctenophores.
