A new pufferfish species

By Leonard Ho - Posted Mar 28, 2016 09:00 AM
Arothron multilineatus is a newest pufferfish species. It is described from four specimens collected off Japan's southern reef. However, based on photographic evidence, it appears this new species is very wide ranging in the Indo-Pacific and also the Red Sea!

Arothron multilineatus

It strikes us that such a conspicuous, large (20 inch/50cm) fish with such a wide-ranging distribution in relatively shallow (SCUBA-depth) tropical waters is only now formally described.  It goes to show how much of the ocean we've yet to discover.

The diagnosis for the formal description is based on physiological descriptions of the collected specimens.  Genetic analysis has not been (yet) performed, so there's a chance that we are actually looking at a hybrid or perhaps  more than one new, closely-related species.
