Description: Body relatively thin, long, and narrow with a medium eye, pointed snout, and a large terminal mouth. Pectoral fins short, pelvic fins long, reaching almost to the vent. Dorsal and anal-fin bases medium, caudal peduncle short and narrow with only 3-4 (three spindly) procurrent caudal-fin rays. Very lightly marked: internal melanophores at the dorsal surface of the swim bladder and one melanophore on the caudal peduncle just after the last anal-fin ray, often deep and indistinct. There are three or four large ctenoid scales along the ventral midline of the caudal peduncle extending from the last anal-fin ray to the start of the caudal-fin procurrent rays. Each spiny scale has two large rear-pointing tines and are outlined in black pigment. Eye shapes range from a slightly narrowed vertical oval to round.
Diagnosis: This genus of long eel-like sponge gobies have normally-proportioned larvae. The genus has notably reduced fin ray numbers: fewer and variable first-dorsal-fin spine numbers (four to seven), many fewer pectoral-fin rays (11-13), and only 3-4 procurrent caudal-fin rays. In addition, they have large spiny scales along the ventral midline of the caudal peduncle. Fortunately the characteristic caudal peduncle scales are prominent on larvae (of E. metzelaari) and confirms the identification. Risor ruber, another sponge goby, also has large spiny scales alogn the ventral midline of the caudal peduncle, but has many more pectoral-fin rays. There are five Caribbean species and the number of fin rays in this genus varies more than usual, often plus or minus two rays around the mode: Evermannichthys metzelaari has a modal fin-ray count of D-IV,15 A-12 Pect-12; E. silus has D-VI-VII,12-13 A-10-11 Pect-13; E. convictor has D-V,11-13 A-9-11 Pect-13; E. spongicola (Gulf of Mexico only?) has D-VI-VII,13 A-10-11 Pect-12; and E. bicolor has a mode of D-VI,11 A-9.
