These snails are pelagic and live at the surface of the ocean. Adult snails may not be capable of swimming, and die when they are detached from their rafts; Janthina janthina larvae, however, actively swim in the water column. [3] The adult snails prey upon (and live near to) one of several species of pelagic animals loosely known as jellyfish.
The snail's oesophageal gland houses symbiotic gammaproteobacteria from which the snail appears to obtain its nourishment. This species is considered to be one of the most peculiar deep-sea hydrothermal-vent gastropods, and it is the only known extant animal that incorporates iron sulfide into its skeleton (into both its sclerites and into its ...

Conch (US: / k ɒ ŋ k / konk, UK: / k ɒ n tʃ / kontch [1]) is a common name of a number of different medium-to-large-sized sea snails. Conch shells typically have a high spire and a noticeable siphonal canal (in other words, the shell comes to a noticeable point on both ends).
Apple snails use the siphon in a way that is reminiscent of a human swimmer using a snorkel, except that the apple snail's siphon can be retracted completely, or extended to various lengths as needed. [6] For these freshwater snails, the siphon is an anti-predator adaptation.
The whimsical lyrics feature animals such as porpoises, snails and lobsters. The snail is invited to join a dance in which he would be cast into the English Channel towards France, but he fearfully declines. The reason is left unspoken in the song, but France is known for its consumption of escargot. [1]
The sea surface microlayer (SML) at the air-sea interface is a distinct, under-studied habitat compared to the subsurface and copepods, important components of ocean food webs, have developed key adaptations to exploit this niche. [40] The ocean-spanning SML forms the boundary between the atmosphere and the hydrosphere.
