The ghost crab is about as big as your hand but as fast as lightning.
The eight-legged little creature moves across sandy beaches at 100 body lengths per second, which is blazing fast compared to the human and cheetah, which achieve speeds of 11 and 20 body lengths per second.
In other words, you’d be lucky to photograph one. Be prepared for it to dash away as soon as it gets a glimpse of you. The ghost crab typically burrows deep holes in the sand and reemerge late in the day.
But within those stalky eyes and cute little faces are teeth that growl at predators when threatened. The ghost crab is the first example of an animal that uses its stomach to communicate.
Meanwhile, the crabs survive off insects, small clams, and other sand crabs.
