For these freshwater snails, the siphon is an anti-predator adaptation. It reduces their vulnerability to being attacked and eaten by birds because it enables the apple snails to breathe without having to come all the way up to the surface, where they are easily visible to predators. [6]
The surface-dwelling nudibranch, Glaucus atlanticus, is a specialist predator of siphonophores, such as the Portuguese man o' war. This predatory mollusc sucks air into its stomach to keep it afloat, and using its muscular foot, it clings to the surface film.
This makes it difficult for predators to remove them from their shell. This is an essential function to have as blue crabs are commonly seen chipping away at the shell ridge in order to feed on the snail. [5] Another method L. irrorata uses to avoid predation is vertical climbing of the grass S. alterniflorus. The snails climb up the grass ...
Argonauts are capable of altering their color. They can blend in with their surroundings to avoid predators. They also produce ink, which is ejected when the animal is being attacked. This ink paralyzes the olfaction of the attacker, providing time for the argonaut to escape. The female is also able to pull back the web covering of her shell ...
Nautilus have been observed to spend days in deeper areas around coral reefs, to avoid predation from turtles and carnivorous fish, and ascend to shallow areas of the reef during nights. [18] [11] Here, they engage in scavenging activity, seeking out animal remains, and the moults of crustaceans. Nautilus species usually travel and feed alone.
Sacoglossans can also use antiherbivory compounds produced by their algal foodstuffs to deter their own would-be predators, in a process termed kleptochemistry. [10] This may be achieved by converting algal metabolites to toxins, [ 15 ] or by using algal pigments for camouflage in a process termed nutritional homochromy.
