genome and the evolutionary origins of neural systems.
An invasive ctenophore
was observed in Mobile Bay and Mississippi Sound, AL in September 2012.
Populations of the jelly-fish-like ctenophore
Mnemiopis leidyi, first noticed in 1982, have erupted--consuming zooplankton, shellfish, and eggs and larvae of fish.
To my knowledge, these groups of bristle-like projections on the epithelial floor of the ctenophore
apical organ have not been described.
The homeodomain complement of the ctenophore
Mnemiopsis leidyi suggests that Ctenphora and Porifera diverged prior to the Para-Hoxozoa.
PARASITIC AMOEBAE OF THE CTENOPHORE
Adapted to limitless, featureless blue surroundings, this planktonic ctenophore
, Cestum, lives near the ocean surface.
1:45 ANALYSIS OF SWIMMING BEHAVIOR BY GELATINOUS ZOOPLANKTON IN ALTERED GRAVITY CONDITIONS: CTENOPHORE
AND CNIDARIAN MEDUSA
The most likely candidates for biocontrol include Baroe, another ctenophore
that eats only comb jellies, and the butterfish, a fish of low commercial appeal with a fairly catholic diet that includes Mnemiopsis.
quinquecirrha preys on, and may control, the ctenophore
Mnemiopsis leidyi (Feigenbaum and Kelly 1984).
Invasion of the Black Sea by the ctenophore
Mnemiopsis leidyi and recent changes in pelagic community structure.
If a ctenophore
is tilted or displaced from a position of vertical balance, it rights itself by asymmetric frequencies of beating on the uppermost and lowermost comb rows, turning to swim up or down depending on its mood.
