Occurs in reefs and rocky outcrops surrounded by sand.
The color of the living is pale, with four elongated rows of brown spots on the back, corresponding to the diameter of the pupil.
The back and sides of the head are covered with irregular brown spots.
The median dorsal row shows 15 spots between the nape and base of the caudal fin, the first three spots on the anterior dorsal region are elongated and appear late; spots at the base of the dorsal fins appear in pairs of closely neighboring spots, separated from the following pairs by wider and lighter spaces; the last four spots on the caudal peduncle are less distinct.
A dorsal upper-dorsal row of 19 spots, extending from the upper edge of the operculum to the base of the tail, can be seen.
A lower dorsolateral row of about 13 spots, sometimes merging posteriorly with the upper dorsolateral spots, and a row of about 11 spots on the lateral midline, extending from behind the base of the pectoral fin to the caudal root.
A V-shaped marking, half obscured by the operculum, at the base of the pectoral fin.
On the proximal portion of the pectoral fin rays 3 to 7 there is a spot, and a corresponding spot on the axillary side of the fin, the rest of the fin is clear.
A dark crossbar is located at the base of the caudal fin.
Dorsal and anal fins are dark on the distal half, the disc of the pelvic fin is also dark.
The caudal fin is clear.
An internal vertical striation pattern on the branchial membrane and median skelettogenic septum is visible through the muscle wall in live specimens.
Two longitudinal spots on the branchial membrane, two stripes extending between the bases of the dorsal and anal fins, and a third stripe between the posterior base of the dorsal fin and the ventral edge of the caudal peduncle.
Etymology:
The species is named in honor of Mr. Edwin Janss Jr. in recognition of his support and encouragement of research in the marine sciences. All known specimens of Elacatinus janssi were collected by the Janss Foundation's RjV Searcher.
