Horseshoe Crab Birth | Tachypleus tridentatus

This scene depicts the birth of juvenile endangered Japanese horseshoe crabs (Tachypleus tridentatus). During spawning, an adult female deposits clusters of dozens of eggs, which are fertilized by a male that is attached to the female during the spawning season. The gestation period is approximately two months. Juveniles emerge at the same time, sometimes one by one, sometimes in groups like this.
