List of critically endangered molluscs facts for kids
Imagine a world where some of the most amazing creatures are slowly disappearing. That's what's happening to many molluscs, which are soft-bodied animals often protected by a shell, like snails, slugs, and clams. As of September 2016, the International Union for Conservation of Nature (IUCN) has listed 581 types of molluscs as critically endangered. This means they are at an extremely high risk of disappearing forever from the wild. Out of these, 117 are even thought to be possibly extinct, meaning they might already be gone.
About 8% of all mollusc species that have been checked are critically endangered. The IUCN also lists 11 mollusc subspecies (which are like different versions of a species) in this same danger category.
It's also important to know that for many molluscs (about 27% of those checked), there isn't enough information to figure out how endangered they are. These are called "data deficient" species. Since these species often live in small areas or have small populations, scientists believe they are probably also in danger. The IUCN suggests we should pay close attention to them, just like the clearly threatened ones, until we know more.
This list shows some of the mollusc species and subspecies that are critically endangered. If a species is marked as "possibly extinct," it means scientists haven't seen it in a long time and worry it might be gone.
