Craspedotropis gretathunbergae[1] is a species of snail in the family Cyclophoridae.

The species was discovered in Brunei by a team of citizen scientists and subsequently named after climate activist Greta Thunberg.

[2] After the discovery of the species, a vote was conducted among the members of the expedition and the staff of the national park, and a decision was made to name it after Greta Thunberg.

According to the scientists, this was a "way of acknowledging that her generation will be responsible for fixing problems that they did not create".

Specimens of the species were found on a steep hill, next to a river bank, while foraging at night on the green leaves of understory plants.
