Striped Barracuda (Sphyraena obtusata) タイワンカマス
These Striped Barracuda were hard to identify. there are many types of small schooling Barracuda, they change their appearance somewhat depending on environment to blend in, and there is a lack of good pictures to compare to. I hope that I got it right. Amami
Same school of Striped Barracuda as above. It was a big school. Amami
