Deep-Sea Ghost Sharks Develop Forehead Teeth to Enhance Feeding

Originally Published 3 months ago — by SciTechDaily

Male ghost sharks have a unique forehead structure called a tenaculum covered with true teeth, which helps in mating. This discovery, supported by fossil, genetic, and modern specimen analysis, reveals that these teeth are genuine and develop outside the mouth, showcasing evolutionary flexibility and adaptation in deep-sea fish.

Ghost sharks develop forehead teeth to aid in reproduction

Originally Published 4 months ago — by Phys.org

A study reveals that male ghost sharks have a unique forehead appendage called a tenaculum, covered in rows of teeth similar to those in their mouths, which is likely used for mating. This structure demonstrates the evolutionary reuse of oral teeth development for reproductive purposes, highlighting the remarkable adaptability of tooth formation in deep-sea fish.
