Etymology: Karsten: Named for Karsten E. Hartel, Curatorial Associate in Ichthyology at the Museum of Comparative Zoology, Harvard University (Ref. 43739). More on author: Garman.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 0 - 1122 m (Ref. 43739), usually 0 - 55 m (Ref. 43739). Tropical; 12°N - 19°S, 117°E - 178°W
Western Pacific: Fiji, Indonesia and the Philippines; probably more widely distributed.

Morphology | Morphometrics
soft rays: 40 - 44;
Vertebrae: 28 - 31. This species is distinguished by having spinous pterygiophore formula 3-123, 3-132, or 3-122 + 2. (here the 6th spine shares its interneural space with the 2 pterygiophores associated with the first 2 dorsal fin soft rays) (vs. 3-1221 or 3-12210 in other amblyopines); precaudal vertebrae 9 (vs. 10 ) (Ref. 43739).
Collected over mud and sand bottoms. Its small size and deep-dwelling habitat makes collection a difficult task (Ref. 43739).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00322 - 0.01708), b=2.98 (2.78 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (11 of 100) .
