Sea Walnut - Mnemiopsis leidyi
Noce di Mare Mnemiopsis leidyi Sea Walnut ctenoforo ctenophore
We also met us Mnemiopsis leidyi or Sea Walnut, which would seem one of many jellyfish found in the seas around the world and also in the Mediterranean. But it really is a Ctenophore and how many Ctenophores is bioluminescent, we slowed the movie to see the effect.
Mnemiopsis is an invasive species, and in some European waters it caused enormous economic damage whereas you think that is able to change greatly entire ecosystems and drastically reduce the fish fauna of the areas that can colonize.
