Deep-sea ghost sharks, also known as chimaeras, have baffled scientists for years with their unusual forehead teeth. Recent research finally sheds light on this fascinating adaptation.
Ghost Sharks’ Unique Mating Tool
Male ghost sharks possess a tooth-studded rod on their foreheads. They use this rod during mating to latch onto females. Scientists have now confirmed—using fossil and genetic evidence—that these rods are made of real teeth, not just bony projections. 
Evolutionary Adaptation Unveiled
This discovery highlights the incredible evolutionary flexibility of these deep-sea creatures. The forehead teeth help males grip females securely, ensuring successful reproduction in the challenging deep-sea environment. Chimaeras are closely related to sharks and rays, but their bizarre adaptations set them apart in the world of ocean life.
