Born Without Teeth

4. Born Without Teeth

A glaring absence of skin and skin structures is not the only thing rare about this unique little swimmer – it also did not have any teeth whatsoever! Normally, the upper jaw of blackmouth catsharks is known to have around 69 rows of small-sized teeth, while the lower jaw contains as many as 79 rows of teeth.
