Snails
Snails are mostly known for their speed, or lack thereof. We get it, they’re not the fastest animal on Earth. But there are plenty of other things about snails to amaze.
1. THEY’RE NO DIFFERENT FROM SLUGS …
The only measurable difference between snails and slugs is that the former has a shell.
2. THOUGH SOME SLUGS ONLY APPEAR TO BE SHELL-LESS
In reality, slug families such as Limacidae and Milacidae have internal shell plates hidden within their bodies. Smaller shells can help the creatures to be more mobile, an evolutionary advantage when it comes to chasing down prey.
3. THEY’RE RELATED TO SHELLFISH.
Slugs and snails are mollusks, putting them in the same category as oysters, clams, and mussels. Gastropods (the taxonomic class for snails and slugs) are the largest group of mollusks, comprising more than 80 percent of living mollusk species. They’re also one of the most diverse groups of animals in terms of form, habitat, and behaviors.
4. THEY LIVE EVERYWHERE ON EARTH.
There may be as many 150,000 species of gastropods, and they live in almost all habitats, from deep ocean trenches to deserts.
