An international team of researchers from the UK and the Azores publish their discovery in the Journal of Fish Biology.

The seahorse was found by a fisherman on the isolated Azores archipelago in the eastern Atlantic.
Two species of seahorse Hippocampus guttulatus and Hippocampus hippocampus are native to Europe and the Azores, an autonomous region of Portugal.
We were surprised to identify the unknown seahorse as H. erectus, as this species is found thousands of kilometres away

The researchers compared the morphology and DNA of the seahorse with the two native species and found it was a lined seahorse Hippocampus erectus usually found along the Atlantic coast and Caribbean sea coasts of North, Central and South America….”
