The sensory organs of gastropods (snails and slugs) include olfactory organs, eyes, statocysts and mechanoreceptors. [1] Gastropods have no sense of hearing. [1]

Slug, or land slug, is a common name for any apparently shell-less terrestrial gastropod mollusc.

Scientific name: Testacella haliotidea. 7-10cm at maturity. Colour creamy-white to yellow-brown, commonly darkening towards the tail tip. Colour uniform and without distinct markings. It has a small, often slightly convex, ear-shaped shell near the tail.

Jan 15, 2014 · Slugs and snails do not have ears and a nose like we do but they can still smell and they can detect some sounds through vibration. They use either their eye tentacles or two smaller tentacles below the eye tentacles for these senses.

Slugs are very efficient in the use of their body parts. The mantle encloses and protects the slugs internal organs, pumps water and filters out food, and stores eggs while they mature.

Can slugs see you? SLUGS HAVE TENTACLES, BLOWHOLES, AND THOUSANDS OF TEETH. First, check out the tentacles. Slugs have four, and they're retractable. Two are for seeing and smelling, and they can be operated independently: a slug can gaze at you (or smell you) and a friend simultaneously. The other two are for touching and tasting.

The British Ear-shelled Slug (Testacella halotidea), shown at fig. 162, is one of these. It is about 2 1/2 in. long, deep yellow in colour, and may be recognized by a small ear-shaped shell attached to its back, just above the tail.

The shelled slug, scientific name Testacella haliotidea, is a rarely seen, air-breathing, carnivorous land slug, a terrestrial gastropod mollusk in the family Testacellidae, the shelled slugs.

Dec 16, 2018 · “Sea slugs” include both the by far most famous nudibranchs, and groups such as the Sacoglossa (sap-sucking slugs, more about these later in the calendar!) and Cephalaspidea (the bubble snails), amongst others.

The slug’s eggs are laid under the soil in clutches of up to 40 and turn from white to brown soon after laying. Some eggs in the laboratory took nearly two years to hatch.
