 sea slug. The Columbia Encyclopedia, Sixth Edition. 2001-05
Sea slugs, or nudibranchs, are distributed throughout the world, with the greatest numbers and the largest kinds found in tropical waters.
Most sea slugs have two pairs of tentacles on the head, used for tactile and chemosensory reception, with a small eye at the base of each tentacle.
Certain sea slugs that feed on corals and sea anemones ingest the stinging cells of their prey without discharging them; these then pass from the slug’s digestive tract to the ceratia, where they are used by the slug for its own defense.

SEA SLUG [sea slug] name for a marine gastropod mollusk that lacks a shell as an adult and is usually brightly colored.
A Sea - slug (1,5 cm long) (Coryphella pedata) from the Flabellinidae familia is pictured on a piece of an Eudendrium in the depth of Mediterranean sea near Fethiye, 03 November 2005.
Patrick J. Walsh, professor of marine biology and fisheries at the University of Miami, holds a breeding sea slug on Wednesday, December 10, 2003.

 Aquarium Invertebrates
Elysia crispata is one of the most variably colored sea slugs in the world, ranging from dull green, to bright blue, to almost white, to red, yellow and blue banding on a green background, and virtually every combination in between.
I was pleased to see that the two species of sea slugs in the aquarium happened to be 2 of the more likely sea slugs (sea hares and lettuce sea slugs) to survive in captivity, and there were none of the more colorful and infinitely more difficult nudibranchs that are so often imported.
Sea slug, on the other hand, is a descriptive term that can be applied to any of the shell-less gastropods that live in the sea.

 Augsburg College Biology - Photo of Month - March 2002
This animal is commonly known as the lettuce sea slug, so named because when the animal is at rest the parapodia make this snail without a shell look a lot like a small head of ruffled lettuce.
The lettuce sea slug is not alone in its habit of gaining extra functionality using cellular structures stolen from the organisms it eats.
Some of its relatives (certain of the sea slugs known as nudibranchs) arm themselves with stolen nematocysts (tiny stinging structures produced by the cells of anemones, hydroids, and their relatives) from the cnidarians they eat!

 In the sea slug's defense against lobsters, confusion is key
Like many other marine creatures, Aplysia, a common sea slug, enlists chemical defenses against its predators, but the mechanisms by which such chemical attacks actually work against their intended targets are not well understood by researchers.
Ironically, the slug's ability to trick the lobster's nervous system into activating feeding-associated behaviors succeeds, in combination with ink and opaline's other effects, in distracting the lobster sufficiently to enable the slug's successful evasion.
Because the set of behaviors stimulated by the slug's secretions resemble activation of a feeding pathway, the researchers named this novel chemical defense "phagomimicry." The stickiness of the slug's secretions appears to contribute to long-lasting effects on the target despite the aqueous environment, enhancing the effectiveness of the slug's defense.

One of the most important things a sea slug must do is to learn how to survive in an ocean full of predators ready to eat them.
Whether a sea slug becomes dinner or escapes to live another day will depend on how well the slug learns about and responds to its predators.
A sea slug responds to its predators by reflexively withdrawing the portion of the body that is being pinched.

 Genetic sequence identified for anti-bacterial sea slug protein
When encountering predators, sea slugs discharge a purple ink containing Escapin which chemically resembles toxins of some venomous snakes.
Among its properties, the protein causes foreign cells to lyse or explode and prevents bacteria from growing on sea hares.
Derby, whose team has sequenced, cloned and expressed Escapin, believes a natural or synthetic form of the protein could be manufactured for the marine industry as an environmentally friendly alternative to toxic heavy metals, such as copper, normally applied on materials to prevent biofilm development.

 Sea Slug Explanation   (Site not responding. Last check: 2007-10-22)
The accompanying data file is from a pilot study on the ability of sea slug larvae to detect this kind of seaweed at different tide heights.
Instead of randomly swimming until they find this seaweed (as was previously believed), these larvae actually "smell" the seaweed when they are passing over it in the water.
Fifteen slug larvae were then injected into each of the replicates, and the percentage of larvae that metamorphosed was recorded.

 PIR: Sea Slug
A marine snail called the sea slug (see photo), which resembles a common pond snail without the protective shell, has been conditioned to respond to light flashes.
The sea slug is used for this type of research because it has the largest known, clearly identifiable brain cells in the animal kingdom.
Researchers are thus able to use them to study the roles of brain cells and nerve impulses through the cells.

The sea slug has about 20,000 neurons, and they're large and they're colored and you can in each animal find the same neuron over and over again.
If you could take the ideas about the slug body and create a hydrostatic endoscope that could actually move parastaltically forward, then you could take the physician out of the business of pushing things in and allow him to just focus on guiding it.

 Nudibranch of the Week is Tridachia diomedea
Picture taken at Sal Se Puertes Is. in the Midriff Is. group 100+ miles north of San Carlos, Sea of Cortez by Jerry Allen of Tucson, Az.
The original type specimens of Tridachia diomedea were dredged from 10 fathoms between Punta Gorda and the southwest corner of Isla Cerralvo (24 11' N; 109 55' W) on 30 April 1888.
The most recent discussion of the feeding of Tridachia diomedea and the photosynthetic capabilities of its endosymbiotic chloroplasts is by Cimino & Ghiselin (1998), where they brilliantly analyze the much larger problem of chemical defense and evolution within the Sacoglossa.

The Lettuce Sea Slug may also be referred to as the Lettuce Nudibranch, or Green Lettuce Nudibranch, although it is not a true nudibranch.
The Lettuce Sea Slug incorporates the chloroplasts (the portions of the cell responsible for photosynthesis) from the algae into its tissues, and thus relies on photosynthesis for part of its energy.
It can be harmed by pump intakes and drains, so care should be taken to screen these off.
