Although some paleontologists dispute its classification as a mollusc, it is generally accepted as being at least a bilaterian.
When compared to other APGWa precursors of mollusc, it appears that gastropods more frequently contain the APGWa peptide rather than the TPGWa, RPGWa or KPGWa of bivalves (P. fucata, C. gigas and M. edulis [ 22]).
The diet of the giant freshwater stingray consists of small fishes and invertebrates such as crustaceans and molluscs, which it can detect using its electroreceptive ampullae of Lorenzini.
Although it was thought that the distribution of the FMRFamide itself was limited to molluscs, later it was shown that the FMRFamide is a part of a large family of related peptides (FaRPs) and present in every major metazoan phylum examined.
A cement company blew up the entire hill and all remaining molluscs with it.
So as sensational as leopard slugs' sex lives may be, the slimy lovers may find themselves outcompeted by fellow molluscs when it comes to mystifying mating systems.
The zebra shark feeds primarily on shelled molluscs, though it also takes crustaceans, small bony fishes, and possibly sea snakes.
This mechanism is known as controlled biomineralization, and is widely represented by various organisms (corals, molluscs, birds…); it occurs by direct interactions between organic and mineral phases with no direct actions of cells [ 12, 13, 41].
Even if it was a bilaterian but not a mollusc, its age would indicate that animals were diversifying well before the start of the Cambrian.
The slug-like organism fed by scratching the microbial surface on which it dwelt in a manner similar to the molluscs, although its affinity with this group is contentious.
