Actinopteri (ray-finned fishes) > Tetraodontiformes
(Puffers and filefishes) > Monacanthidae
Etymology: Colurodontis: Latin, color = colour + Greek, odous = teeth (Ref. 45335); paxmani: Named for B. Paxman who was instrumental in obtaining many monacanthid specimens.

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm SL male/unsexed; (Ref. 35708)
soft rays: 26 - 31;
Vertebrae: 19. Diagnosis: All external teeth with truncate cutting edges. Anteriormost pair in each jaw extending across full width of mouth. Two vertical small tusk-like processes on internal surface of anteriormost pair of teeth in lower jaw. First dorsal spine originates over posterior half of eye, armed with 2 series of prominent downward-directed barbs on anterior face, much smaller and more numerous than those in postero-Iateral rows. Scales on body with 1 central spinule supported by a transverse ridge, those spinules on caudal peduncle of adult male moderately elongate, curving anteriorly. Pelvic bony structure movably articulated with pelvis (Ref. 35708).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.01006 - 0.04340), b=2.93 (2.75 - 3.11), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±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 (22 of 100) .
