Scientists have discovered in the Atlantic waters of Panama a new species of angel shark Squatina mapama, originating from the Cretaceous period, approximately 146-66 million years ago.
A distinctive feature Squatina mapama is a short and narrow line of small scales. A common feature of this species of sharks — flat, like a stingray, the body.
Using genetic analysis, the researchers were able to attribute the discovered shark to a separate species. Based on the distinctive feature of the scales, scientists proposed to name the new species — "small-crested shark— angel".
