A member of the clingfish family (Gobiesocidae), small fish with sucking discs instead of swim bladders that allow them to cling to rocks.
From 'gobiesoc-' (the genus name combining 'goby' and Latin 'soccus' meaning sock/slipper) plus '-id' meaning a member of that group; created by Carl Linnaeus to describe their distinctive shape.
Clingfish can stick to rocks with 10 times more force than their body weight—they're nature's suction cup engineers!
