Tokyo, May 24 (Jiji Press)–Crabs walking sideways originated from an ancestor that roamed the Earth some 200 million years ago, according to a team led by Yuki Kawabata, an associate professor of Nagasaki University’s Graduate School of Integrated Science and Technology.<\/p>\n

Crabs’ iconic lateral shuffle “has an advantage in escaping from predators, such as being able to move left and right quickly and making it difficult to predict escape directions,” Kawabata said.<\/p>\n

He suggested that the crabs’ evolution to adopt sideways walking may have helped the crustaceans diversify and succeed.<\/p>\n

The team recorded movements of 50 crab species–35 species that had adopted sideways walking and 15 species that walked forward.<\/p>\n

Comparing this data to the latest phylogenetic tree analyzed at a genetic level, the team aimed to deduce when the sideways walking had originated.<\/p>\n
