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]

Behaviorally, cockles live buried in sediment, whereas scallops either are free-living and will swim into the water column to avoid a predator, or in some cases live attached by a byssus to a substrate. The mantle has three apertures (inhalant, exhalant, and pedal) for siphoning water and for the foot to protrude.
While animals performing distraction displays are rarely documented as being killed, risks to the displaying animal do exist. [33] One researcher observed and documented an instance in which a second predator became attracted to an animal already performing a distraction display. The displaying animal was killed by the second predator. [33]
To do so, they gathered up the debris underneath their bodies using their arms. They then used their siphon, a tube-like part of their body, to expel water aimed at the debris.
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 ...
