  2. Cockle (bivalve) - Wikipedia

    en.wikipedia.org/wiki/Cockle_(bivalve)

    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.

  3. Siphon (mollusc) - Wikipedia

    en.wikipedia.org/wiki/Siphon_(mollusc)

    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]

  4. Peltodoris atromaculata - Wikipedia

    en.wikipedia.org/wiki/Peltodoris_atromaculata

    Peltodoris atromaculata, more commonly known as the dotted sea slug or sea cow, is a species of sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Discodorididae. [1] It dwells in salt water up to the depth of 40m. It is exclusively found in precorralligene and coralligene communities and is very common in such communities. [2]

  5. Marine microbial symbiosis - Wikipedia

    en.wikipedia.org/wiki/Marine_Microbial_Symbiosis

    They emit light during night time to camouflage themselves against the moon and star light coming down the ocean. It helps them to avoid predators. The symbiosis process begins when Peptidoglycan shed by the sea water bacteria comes in contact to the ciliated epithelial cells of the light organ. It induces mucus production in the cells.

  6. Chiton glaucus - Wikipedia

    en.wikipedia.org/wiki/Chiton_glaucus

    In estuarine sites Chiton glaucus are found under bivalve shells and stones, particularly cockles as to avoid visual predators during daylight hours. [2] This is compared to being found on stones and cobbles in more exposed areas. [2] This chiton is able to survive in muddy areas, particularly estuaries. [7]

  7. Marine larval ecology - Wikipedia

    en.wikipedia.org/wiki/Marine_larval_ecology

    A more common avoidance strategy is to become active at night and remain hidden during the day to avoid visual predators. Most larvae and plankton undertake diel vertical migrations between deeper waters with less light and fewer predators during the day and shallow waters in the photic zone at night, where microalgae is abundant. [11]

  8. Aplysia - Wikipedia

    en.wikipedia.org/wiki/Aplysia

    Aplysia species was once thought to use ink to escape from predators, much like the octopus. Instead, recent research has made it clear that these sea slugs are able to produce and secrete multiple compounds within their ink, including the chemodeterrant Aplysioviolin and toxic substances such as ammonia for self-defense. [ 13 ]

  9. Torsion (gastropod) - Wikipedia

    en.wikipedia.org/wiki/Torsion_(gastropod)

    This may help the gastropod locate food or avoid predators. In terrestrial species, ventilation is better with anterior positioning. This is due to the back and forth motion of the shell during movement, which would tend to block the mantle opening against the foot if it was in a posterior position.
