There’s good and bad shark news. The good news is that a new, as of yet unnamed, species has been discovered. The bad news is that it looks just like the scalloped hammerhead shark, curtailing efforts to save that endangered species.
The new look-alike hammerhead is identical to its near twin save for a few important differences:
- distinctive DNA
- 20 fewer vertebrae (about 170 versus 190)
- a genetic profile suggesting it separated from the scalloped hammerhead 4.5 million years ago
That’s an incredibly long period of time, considering how similar the two different sharks look externally.
