Prionodes baldwini Evermann & Marsh, 1899 Serranus baldwini, the lantern bass, is a species of marine ray-finned fish, a sea bass from the subfamily Serraninae, classified as part of the family Serranidae which includes the groupers and anthias.

Serranus baldwini has a cylindrical and elongated body,[3] which is laterally compressed to a moderate extent and has a snout which has a length which is shorter than the diameter of the eye.

[4] The body is white broken by lines of dark to orange oblong-shaped blotches and spot.

[1] Serranus baldwini is a marine reef-associated species, living in rocky and weedy areas at a depth of 1 – 80 m.[2] It shows a strong association with beds of turtle grass (Thalassia testudinum), although juveniles use the empty shells of conches to hide in.

[6] The specific name honours the artist on the expedition of December 1898 aboard the United States Fish Commission steamer Fish Hawk to Puerto Rico which collected the type, Albertus Hutchinson Baldwin (1865-1935).
