Okay, I’ll admit it — I picked this week’s animal solely because it looked super fun to draw. When I think of brightly coloured, beautiful animals, snails don’t usually come to mind. But there’s a certain genus of snails, known as Liguus, that are well-known for their amazingly vivid shells.
There are currently five species of Liguus snail, though there are many subspecies classified under each species of Liguus. Originally some of the subspecies were thought to be completely different species because their shells were very different in colour, but it turns out these snails just have a lot of intraspecific variety in their shells. Liguus fasciatus alone is known to have more than 120 different colour varieties.
Liguus snails are found in a relatively small range, with most species restricted to Cuba and Hispaniola. One species, Liguus fasciatus, is also found in southern Florida. Liguus snails are terrestrial, and spend most of their time in trees, and prefer trees that have smooth bark. I guess if you have to slime your way across a surface, you wouldn’t want it to be super rough.
Do you know what snails eat? I had never actually thought about it. Liguus snails feed on a tasty and nutritious diet of moss, fungi and algae. They forage for their meals on the trees they live on, scraping these lovely morsels off the bark. Sounds delicious, doesn’t it?
Liguus snails are fairly big for snails, with their average size being about four centimeters in length, though they can get up to six centimetres long. As I mentioned before, these snails are known for their magnificently coloured shells. One species, Liguus virgineus, is commonly known as the candy cane snail because its striped shell looks a lot like a a candy cane (in snail form). Though I’m not quite sure what flavour candy cane it would be…
There is certainly a downside to having such colourful shells: people think they are pretty, so they collect them. Over-harvesting of Liguus snails have led to a decline in the species, and habitat destruction isn’t helping the problem. It is now illegal to collect Liguus shells, so hopefully that helps keep these guys around for a while.
