Japanese Anthias Articles and photos by
Scott W. Michael and Keisuke Imai

In this guide to Japanese Basslets, we will take a look at some of the fishes of the subfamily Anthinnae. These include some of the most stunning fishes in the sea! In Japan, there are locations where one can observe some of the deepwater basslets at relatively safe diving depths. We will discuss the natural history of these and other basslets, including some new information on the taxonomy of members of the genus Pseudanthias and photos of some of the odd fishes known as perchlets (genus Plectranthias).

The waters of Japan are home to some of the most amazing reef creatures on the planet. This is in part due to the fact the environmental conditions are quite varied off certain parts of the Japanese coastline.In the north, the waters are cold, while in southern Japan, lush coral gardens grow. In between these two extremes, one can find an amazing marine fauna, including a wonderful basslet community.
