Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 75 - 88; Spine anali: 0; Raggi anali molli: 59 - 69; Vertebre: 41 - 45.
Rare species (Ref. 34024) notable for its strict association with true reef environments and particularly so with outer reefs and reef cores (Ref. 81230). An indweller of deep interstices of lagoon and seaward reefs to a depth of at least 30 m (Ref. 1602). Ovoviviparous (Ref. 240). Solitary inhabitant of shallow water, cryptic (Ref 90102).
Ovoviviparous. Sexes can be readily distinguished by the male's intromittent organ and the female's genital pore (Ref. 240, 205). On the basis of this morphology, copulation may involve flexion of the male's body and pumping of sperm into the female (Ref. 240). Embryos are retained in the ovaries until about 6 mm long, deriving nourishment from large yolk sacs, making the species ovoviviparous rather than viviparous (Ref. 240).
