It’s the largest species of gastropod in American waters, anyway. Lovingly referred to as the Florida horse conch, Triplofusus giganteus is a marine mollusc, whose enormous size and orange body makes it distinguishable on the ocean floor.
This huge snail feeds primarily on other species of marine snail. Btw, the largest species of marine gastropod is the Australian False Trumpet Snail (Syrinx aruanus).
…a species of terrestrial neocyclotid gastropod that is endemic to the island of Dominica in the west indies. Its type locality was in Lauday but it has been described in several other areas throughout the island. Like many other tropical snails A. amethystinus likely inhabits vegetation and feeds on detritus and plant matter.
Caribbean flamingo tongue snail (Cyphoma gibbosum). Often mistakenly caught by shell collectors for its superb colours, its shell is in fact white. The bright colours are only due to the fleshy mantle of the living creature.
…is a colorful species of moon snail (Naticidae) that can be found throughout the waters of the Pacific. Like other moon snails N. orientalis is a predator and fees mainly on bivalves and other shelled molluscs. Once N. orientalis finds a prey item it will envelop the prey and bore a hole into its shell using its radula and a secretion. Once the hole is made it will insert its proboscis into the hole and consume it.
…is a species of sacoglossan sea slug that is distributed throughout the Mediterranean but is thought to range all the way to the Caribbean. Elysia timida feeds mainly on the algae Padina pavonia and Acetabularia acetabulum and like its more popular cousin (E. chlorotica) it stores their chloroplasts and uses them to continue photosynthesis inside its own body.
…is a species of moon snail (Naticidae) that occurs throughout European waters and in the Mediterranean sea. Like other moon snails N. hebraea is a predator and feeds mainly on bivalves, although they will attack other shelled molluscs as well. Once a prey item is sighted the snail will envelop the prey and bore a hole into its shell using an acid secretion and its radula. Once the hole is bored N. nebraea will insert its proboscis into the prey and consume it.
Study shows ‘solar powered’ sea slugs can survive long term in the dark
(Phys.org) —A team of researchers from Germany and the Netherlands has found that at least two species of sea slug thought to be able to endure long periods of starvation by gleaning energy from the sun has found that the slugs can live for long periods of time without food and with or without sunlight. In their paper published in Proceedings of the Royal Society B: Biological Sciences, the team describes experiments they conducted with the slugs and then outline their findings.
The two types of sea slugs (Plakobranchus ocellatus and Elysia timida) survive by eating algae, but prior research has shown that the creature can survive very long periods of starvation. Because the slugs do not digest—at least right away—a specialized subunit of cells known as an organelle, that in the algae is responsible for photosynthesis, scientists have believed that the slugs were somehow gaining energy from the sun using the cells from the algae…
Also known as the granulated nassa, the granulated dog whelk is a species of nassariid gastropod (dog whelk) that occurs in the Indo-West Pacific. Like other nassariids N. graniferus typically inhabits mud flats or sandy bottoms and is an active scavenger, feeding on carrion and small invertebrates. N. graniferus is usually seen burrowed into the substrate with only its siphon showing, waiting until is ‘smells’ food.
Ouch! Hermaphrodite Sea Slug Stabs Mate in Head During Sex
by Laura Poppick
One newly described hermaphroditic sea slug has taken violent animal sex to a new level by stabbing its mates in the head.
The perpetrator of this bizarre act, Siphotperon sp. 1, is a small sea slug found off the northeast coast of Australia. A simultaneous hermaphrodite, it has both male and female reproductive organs that it uses simultaneously during sex.
For its male organ, the slug has a two-pronged penis consisting of a penile bulb that transfers sperm, and a separate, needlelike appendage called a penile stylet that stabs and injects partners with prostate fluid-containing sex hormones called allohormones…
The Crested Aeolis, Janolus cristatus, is a large nudibranch (sea slug) growing to at least 75 mm (3 inches). It is semi-translucent and its body is covered in outgrowths (cerata) that greatly extend the surface area and aid in respiration.
Janolus cristatus lives in shallow sublittoral conditions, especially on sheltered rocky coasts in European waters. It’s preferred food are bryozoans (moss animals).
…is a adorable species of helicinid land snail that is endemic to the island of Dominica in the West Indies. Like other snails this species makes its home on wet leaves, and is active after rainfall and in damp areas (usually in leaf litter). It is believed to feed on encrusting algae.
