  2. 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.

  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. Nautilus (genus) - Wikipedia

    en.wikipedia.org/wiki/Nautilus_(genus)

    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.

  5. Distraction display - Wikipedia

    en.wikipedia.org/wiki/Distraction_display

    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]

  6. Underwater camouflage - Wikipedia

    en.wikipedia.org/wiki/Underwater_camouflage

    Leafy sea dragon avoids recognition by predators, with alga-like coloration, protuberances and behaviour. Underwater camouflage is the set of methods of achieving crypsis—avoidance of observation—that allows otherwise visible aquatic organisms to remain unnoticed by other organisms such as predators or prey.

  7. 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.

  8. 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]

  9. Marine food web - Wikipedia

    en.wikipedia.org/wiki/Marine_food_web

    The linkages between predator to prey are coloured according to predator group origin, and loops indicate within-group feeding. The thickness of the lines or edges connecting food web components is scaled to the log of the number of unique ROV feeding observations across the years 1991–2016 between the two groups of animals.
