Ptéropode : Ce petit escargot de mer (le ptéropode Limacina helicina) joue un rôle important dans la chaîne alimentaire et le fonctionnement de l'écosystème marin Arctique. Sa coquille calcaire constitue une protection vitale. Or, une étude montre que cet escargot construit sa coquille à une vitesse 30 % plus faible lorsqu'il est maintenu dans une eau de mer ayant les caractéristiques chimiques attendues pour la fin du siècle.© S.

Embryos and larvae
Drifting in the currents, embryos and larvae perpetuate the species and are food for multitudes.

Siphonophores - The longest animals on the planet
Cousins of corals, siphonophores are colonies of specialized individuals called zoids. Some catch and digest their prey, others swim, or lay eggs or sperm.
