Researchers discover ghost sharks have tooth-like structures on their foreheads to aid in mating.
Researchers found that ghost sharks, or chimaeras, grow specialized teeth on a forehead appendage called the tenaculum to help grasp females during mating.
These teeth are genetically similar to those in the mouth, not to shark skin denticles, showing evolution's adaptability in repurposing structures.
The study, using CT scans and genetic analysis, highlights the ocean's hidden biodiversity.
