A 50-second video of snails (most likely Natica chemnitzi and Cerithium stercusmuscaram) feeding on the sea floor in the Gulf of California, Puerto Peñasco, Mexico. A hermit crab occupying a shell of Acanthina punctulata has been disturbed, and has retracted into the shell, using its claws to bar the entrance in the same way the snail used its ...
The blue-ringed octopus's rings are a warning signal; this octopus is alarmed, and its bite can kill. [42] A few species of molluscs, including octopuses and cone snails, can sting or bite. Some present a serious risk to people handling them. However, deaths from jellyfish stings are ten times as common as those from mollusc bites. [43]
Turbo bruneus, common name the brown (Pacific) dwarf turban or the little burnt turbo, is a species of sea snail, marine gastropod mollusk in the family Turbinidae. [1] These snails are called "turbo" because they can move quite quickly for a snail [dubious – discuss], using a muscular foot to glide along the ocean floor.
Conus textile, the textile cone or the cloth of gold cone [3] is a venomous species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails, cone shells or cones. Textile cone snails live mostly in the Indian Ocean, along the eastern coast of Africa and around Australia.
It lives in reefs of the tropical Indo-Pacific, and hunts small fish. While all cone snails hunt and kill prey using venom, the venom of Conus geographus is potent enough to kill humans. [3] The variety Conus geographus var. rosea G. B. Sowerby I, 1833 is a synonym of Conus eldredi Morrison, 1955. This species is the type species of :
There are approximately 30 records of humans killed by cone snails. Human victims suffer little pain, because the venom contains an analgesic component. Some species reportedly can kill a human in under five minutes, thus the name "cigarette snail" as supposedly one only has time to smoke a cigarette before dying.
J. janthina is a member of the family Janthinidae, snails that trap air bubbles to maintain their positions at the surface of the ocean, where they are predators on hydrozoa. [6] The air bubbles are stabilized by the secretion of amphiphilic mucins which have evolved from epitoniid egg masses. [7]
Cone snails, or cones, are highly venomous sea snails of the family Conidae. [1] Fossils of cone snails have been found from the Eocene to the Holocene epochs. [2] Cone snail species have shells that are roughly conical in shape. Many species have colorful patterning on the shell surface. [3] Cone snails are almost exclusively tropical in ...
