海 関連する礁; 深さの範囲 1 - 21 m (Ref. 52313). Subtropical; 32°N - 33°S
Western Atlantic: Bermuda and the Bahamas to Santa Catarina, Brazil (Ref. 57756); including lower east Florida coast but absent from the Gulf of Mexico except for a single record from Cayo Arcas, Mexico. Dawson (1982) noted that there are two distinct color patterns of this species with no definite intergrades. Some authors are of the opinion that these color extremes represent two different species and should this be true, Dawson stated that Kaup's vittatus has priority over ensenadae with AMNH 7792 documenting the Bermuda occurrence of Micrognathus vittatus.

背鰭 (合計) : 19 - 21; 臀鰭: 1 - 3. Possess nine (9) different color phases. Similar to Halicampus zavorensis, it has a short snout (2.7-3.7 in HL) with a continuous and essentially linear median dorsal ridges. Different with H. zavorensis in having 17-18 trunk ridges (vs. 14); 32 - 35 tail rings (vs. 36 - 37); and having 18 - 22 dorsal-fin rays (vs. 22 - 23) (Ref. 52313).
Occurs in pockets of coral rubble (low coral growth on white sand bottom), usually in the vicinity of sea fans (Ref. 5521, 7251, 9710). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
