What to know about New museum find shows nature can't stop inventing seahorses

Researchers have identified a new genus of fish, Australyichthys, from the deep reefs of southern Australia that resembles seahorses due to convergent evolution. Using micro-CT scanning and DNA sequencing, the study determined these 'sea muppets' are a distinct lineage from true seahorses.

What happened

New museum find shows nature can't stop inventing seahorses Swati Mestri Scientific Editor Robert Egan Senior Editor At first glance, it looks exactly like a seahorse.

Why it matters

It has the same horse-shaped head tilted down from the body, the same curled, grasping tail and, in the males, a fully enclosed pouch for brooding the young.

Common ground

But this little fish, no longer than your thumb, is not a seahorse, as we report in our new study published in the Journal of Lost Species.
