The curious case of crabs’ sideways movement: An evolution 200 million years in the making
Crabs' signature sideways scuttle, a mystery for ages, has been traced to a single evolutionary event 200 million years ago. This unique movement, observed in 35 out of 50 studied species, provided a significant survival advantage, allowing for quick escapes from predators. This ancient behavioral breakthrough likely fueled the widespread success of 'true crabs' across diverse global habitats.
