Extinct

The subspecies has now been removed from the Endangered Species Act, 80 years after its last sighting.

The disappearance of a tiny oceanic parasite, researchers warn, indicates that overfishing has caused an ecosystem to fall out of balance.

They may not be the most charismatic group of species, but we can learn a lot from the lowly snail.

Extensive searches for this tiny microbat have failed to locate any survivors. The exact cause of its extinction remains unknown.
