生態學
海洋 礁區魚類; 深度上下限 1 - 21 m (Ref. 52313). 亞熱帶的; 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.
西大西洋: 百慕達群島與巴哈馬到巴西聖保羅;(參考文獻 57756) 包括低的佛羅里達東部海岸但是墨西哥灣除了來自 Cayo 檳榔，墨西哥的一個記錄沒有出現。 道生 (1982) 被記錄到以有二個明顯彩色斑紋這沒有明確的中間等級的魚種。 一些作家是這些彩色極端代表二個不同的種的意見與應該這是真實的, 道生陳述了 Kaup 的 vittatus 用 AMNH 7792 証明 Micrognathus vittatus 的百慕達群島發生有在 ensenadae 上的優先.

簡短描述

背的軟條 (總數) : 19 - 21; 臀鰭軟條: 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).
Body shape (shape guide): eel-like.
持有九 (9)個不同的色相。 類似 莫桑比克海蠋魚〔Halicampus zavorensis〕 , 它有一個短的吻 (2.7-3.7個 HL比率) 具有一個連續與實質上線狀中央的背部脊。 不同的與 H. zavorensis 有 17-18個軀幹脊;(vs.14) 32- 35個尾環 (vs.36- 37); 而且有 18- 22個背鰭鰭條 (vs.22- 23) (參考文獻 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).
出現於珊瑚殘礫 (低的珊瑚成長在白色的砂質底部上) 的口袋, 通常在海扇的鄰近區域.(參考文獻 5521,7251,9710) 卵胎生的.(參考文獻 205) 雄魚帶卵在一個孵卵袋是在尾部下面發現.(參考文獻 205)
