Description

Banana slugs are usually bright yellow (somewhat resembling a banana) although they may also be green, brown, or white. Some slugs have black spots (A. columbianus ) which may be so extensive as to make the animal look almost solid balck. A yellow Tulip. ... This article or section does not cite its references or sources. ...


The Pacific banana slug is the second-largest species of terrestrial slug in the world, growing up to 25cm (9.8 inches) long (the largest is Limax cinereoniger of Europe, which can reach 30 cm (12 inches) in length) citation needed, Superscript text. This article is about land slugs. ... Binomial name Limax cinereoniger Wolf, 1803 Limax cinereoniger is species of slug from family Limacidae. ... For other uses, see Europe (disambiguation). ...


Slugs use two pairs of tentacles to sense their environment. The larger, upper pair, termed "eyestalks," is used to detect light or movement. The second, lower pair is used to detect chemicals. The tentacles can retract and extend themselves to avoid damage. Tentacles can refer to the elongated flexible organs that are present in some animals, especially invertebrates, and sometimes to the hairs of the leaves of some insectivorous plants. ...


Banana slugs have a single lung which opens externally with a pneumostome. The pneumostome lung cavity is heavily vascularized to allow gas exchange. Banana slugs excrete a thick coating of slime (mucous) around their bodies. Dehydration is a major problem To prevent themselves from drying out, slugs can also estivate: they secrete a protective layer of mucus, and insulate themselves with a layer of soil and leaves citation needed. They remain inactive in this state until the environment is moist again. Human respiratory system The lungs flank the heart and great vessels in the chest cavity. ... Diagram describing the different parts of a slug A black slug, , on a rock, with its pneumostome clearly visible. ... Estivation or aestivation (from Latin aestas, summer) is a state of dormancy similar to hibernation. ...


The coating offers other protections as well. It allows slugs to travel unharmed across the sharp edge of a razor blade or piece of glass, and can thwart predators; the slug excretes thick mucous and humps its body up, making itself appear larger citation needed. When the slime comes into contact with a moist surface, it produces an anasthetic which causes the membranes to go numb (citation needed. The word mucous is an adjective which means pertaining to mucus or having the qualities of mucus. ...


The slime of the banana slug also lubricates the terrain over which they move, so they can travel more easily. When climbing a tree, a slug can drop back down quickly using a string of slime. Researchers have made unsuccessful attempts to reproduce slug slime citation needed, since it is one of the best natural glues, and has potential uses in medicinecitation needed. For the chemical substances known as medicines, see medication. ...


The slime also contains pheromones to attract other slugs for mating. Slugs are hermaphrodites, and reproduce by exchanging sperm with their mate. They produce up to 75 translucent eggs, which are laid in a log or on leaves. Slugs mate and lay eggs throughout the year. The adults provide no further care for their eggs beyond finding a suitable hiding spot, and the eggs are abandoned as soon as the clutch is laid.

Ariolimax dolichophallus, a species of banana slug (dolichophallus meaning "long penis" in Latin) has the largest penis-to-body length ratio of any animal. The record-holding specimen had a body length of 6 inches (15 cm), with a phallus length of 32.5 inches (82 cm), well over five times the body length.[citation needed]


Distribution

Ariolimax columbianus is native to the forest floors along North America's Pacific Coastal coniferous rainforest belt including redwood forests) which stretches from Southeastern Alaska to Central California, just south of the San Francisco Bay Area (Santa Cruz). Several discontinuous populations do occur in forested slopes of the coastal and traverse mountain ranges south of Santa Cruz as far south as Ventura County, with a tiny, isolated population located in Palomar State Park within the Palomar Mountain Range in San Diego County, California. The Palomar Mountains have lush Sierra Nevada-like coniferous forests and black oak woodlands unlike the surrounding semiarid lands of inland San Diego County and mark the southernmost population of banana slugs. Small, isolated populations also occur east of the Pacific Coast such as the in the inland coniferous rainforests of British Columbia's Columbia Mountains (interior wet-belt), just west of the Canadian Rockies, and have been seen at lower elevations near creeks and damp areas of Mount Revelstoke National Park. Small populations of banana slugs have also been seen along creek and damp areas of the western slopes of the Sierra Nevada mountains to the north of Yosemite National Park in California. Slug densities in these outlying areas in the Columbia Mountains, Sierra Nevada Mountains, and areas south of Santa Cruz are low compared to densities in the coastal coniferous rainforest belt and are rather restricted to damp areas near creeks, ravines, and gullies.

Ecology

Banana slugs are detritivores. They process leaves, animal droppings, and dead plant material, and then recycle them into soil. They seem to have a fondness for mushrooms, and they spread seeds and spores when they eat. They move relatively slowly since banana slugs, like all slugs, have only one muscular foot.

Banana Slug Biology (83 words)
A few years ago, the banana slug almost became the official state mollusk of California.
After much debate, a bill in the state legislature to make the banana slug the state's top mollusk passed both the State Senate and Assembly.
Sadly, the bill went on to be vetoed by the governor, whose slug-phobia got the better of him; he felt the slug was too undignified for such an honor
Slugs (1025 words)
Banana Slugs are the largest slugs in North America and the second largest slugs in the world.
Slugs have two pairs of tentacles and even though both are used to locate food sources, there is a difference in the function of each pair.
In a wonderfully entertaining and humorous article called Slimes of Passion, banana slug penises have evolved to be almost as long as their bodies.
