Environment: milieu / climate zone / depth range / distribution range
Ökologie
seewasser riff-verbunden; tiefenbereich 2 - 50 m (Ref. 30874). Tropical; 30°N - 32°S
Indo-Pacific and Eastern Pacific: Persian Gulf and East Africa to the west coast of the Americas. It was noted by Dawson (Ref. 5316) that there is a clinal increase in the number of total rings and dorsal rays for the 3 subspecies (Red Sea, D. e. abbreviatus and Eastern Pacific D. e. paulus (Ref. 86689).
Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 7.0 cm TL Männchen/unbestimmt; (Ref. 9710)
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 21 - 29; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 4. Superior trunk and tail ridges discontinuous; inferior trunk ridge ending on anal ring; lateral trunk ridge continuous with inferior tail ridge; body rings 17-19; tail rings 13-17. Also Ref. 4281.
Uncommon, cryptic species (Ref. 5227), prefers crevices in rocks and corals and areas beneath ledges (Ref. 28023). Occurs in lagoon and seaward reefs to a depth of 45 m or more (Ref. 9710). Benthopelagic (Ref. 58302). Often seen in pairs. Uses its tubelike snout to ingest small crustaceans and plankton (Ref. 28023). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
Life cycle and mating behavior
Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven
Monogamous mating is observed as both obligate and genetic (Ref. 52884). Male carries the eggs in a brood pouch (Ref. 205).
