Description synthétique Morphologie | Morphométrie

Rayons mous dorsaux (Total): 13; Rayons mous anaux: 10 - 11; Vertèbres: 35 - 36. Body small, stout, unpigmented. Body depth at pectoral-fin origin 9-12% of standard length and at anal-fin origin 9-14% SL. First dorsal-fin ray at myomere 18-20 and first anal-fin ray below dorsal-fin ray 4. Vertebrae 20 + 15-16 = 35-36, myomeres 19-20 + 14-16 = 34-36. Premaxillae and dentaries lack teeth. Males have a rod-like, flexible urogenital papilla lacking lobes, projections, or accessory papillae, with distal half tapering to a blunt point and usually anteriorly directed.

Biologie     Glossaire (ex. epibenthic)

Recently reported as the smallest vertebrate. Males average 7.7 millimeters long and the gravid female which is 8.4 millimeters weighed 1 milligram. This pedomorphic species has a life span of only 2 months, has dispensed its fishy appendages such as teeth and scales, and has no pigment except in the eyes (Ref. 52508). Specimens were collected in oblique plankton net tows (Ref. 52019).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Adults with mature gonads while retaining postlarval characters (Ref. 205). Distinct pairing (Ref. 205).
