Why in news
Researchers documented the first case of gynandromorphism in the freshwater crab species *Vela carli* in Silent Valley National Park.
Background
The study, published in Crustaceana, identified three crabs exhibiting both male and female biological traits. The research was a collaboration between the Centre for Conservation Ecology (MES Mampad College) and the Zoological Survey of India.
