Sexual Parasitism: Anglerfish’s Strategy To Conquer the Deep Sea Amid Global Warming

reveals that sexual parasitism in anglerfishes originated during a major global warming event that led to their transition from the ocean floor to the deep sea. This adaptation facilitated rapidMembers of the vertebrate group including anglerfishes are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate.

“We show that this happened more recently than thought after the extinction of the dinosaurs. After that, anglerfishes rapidly diversified in the ‘midnight’ zone of the oceans, which is likely a result of the ecological opportunities afforded by this new habitat. We show how the evolution of one of the strangest aspects of anglerfish biology, sexual parasitism, likely facilitated, but did not directly cause, this diversification.
