Info

Lethrinus haematopterus is currently only known to inhabit Asian waters and Micronesia, specifically Palau.
This sedentary snapper lives in lagoons, seagrass beds, and coral reefs.

Lethrinus haematopterus's body color is olive gray with scattered irregular dark spots, and its head is also gray, sometimes with two blue stripes running from the eye to the front.
The fins of the Chinese street sweeper are pale or gray, and the dorsal fin has a reddish edge.
The blue stripes around the eyes and the red spines on the dorsal fins help to identify this snapper.

In 2019, a parasite was reported in Japan that infests Lethrinus haematopterus and attaches itself to the body surface and in the gill cavity.
Benedenia ishikawae (Goto, 1894) Monticelli, 1902, is the scientific name of the parasitic hookworm.

Etymology:
The species name “haematopterus” is composed of ‘hematos’ for bloody and “pterus” for fin and refers to the blood-red coloration of some or all of the fins of the species.
