first victim – Albadra banded snail

The Aldabra banded snail lived on the Seychelles Islands in the Indian Ocean. Biologist Justin Gerlach of Oxford University says it had very pretty shell: dark, purplish blue with an orange band around. Smaller shells, once common, disappeared with the frequent long, hot summers.

He suspects — but cannot prove — that these bad summers are a side effect of global warming. If he’s right, then this snail has earned itself a grim distinction: It would be the first species in the modern era to become extinct as a direct result of climate change.
