There are much wiser ways to deal with the pests. In my opinion, it is not necessary to kill slugs and snails using any of the methods described above. Slugs do not really have a proper brain, but they do have knots of nerve cells which are capable of processing a myriad of sensory inputs, from the eyes to the touch receptors on the animal’s fleshy underside.īut it doesn’t have a cerebral cortex – that’s the part of the brain responsible for the conscious perception of pain.” So I shouldn’t worry about salting a slug, or chopping it in two with my hoe? “Because a slug responds to a stimulus that we think is painful doesn’t mean it is experiencing pain,” says Chudler.
The ‘skin’ is dried, and form a major fishery in Asia and parts of the Pacific. These are variously called sea cucumbers, holothurians, beche de mer, trepang, etc.
‘True’ sea slugs are molluscs – in fact specialised snails. Have a look at the page on the Dorid head for a photo of a nudibranch eye.

The eyes in sea slugs are embedded in the skin not on stalks like land snails. Yes, all sea slugs have eyes but they aren’t very good at seeing things. So, can slugs really bite? So yeah, slugs can bite. People often wonder whether these creatures can bite their skin or harm them in any way. Slugs mainly feed on leaves of plants and dead and decayed organic matter with the help of specialized teeth. Sea slugs naturally produce toxins to deter predators, such as fish, from eating them because they are vulnerable, being soft-bodied and slow-moving. Some sea slugs are toxic, but this sea slug has not previously been known to contain this particular toxin.
Because of their small size, these animals are vulnerable to many other sea creatures. Sea Slugs: What eats sea slugs? Fish, crabs, and lobsters are all predators of these animals.
