Morphology | Morphometrics
soft rays: 10 - 11;
Vertebrae: 27. Body white, with 3 reddish-orange stripes. Head with 2 median cephalic sensory pores. First dorsal fin extremely long, with longest spine, 64-109% SL; first 2 spines and membrane white. Black spot on middle of first dorsal fin distally. Second dorsal fin rays I, 10-12. Caudal fin rounded (Ref. 40962); characterized further by: united pelvic fins, well developed frenum present; longitudinal scale series 82-96; head without scales; cycloid scales covering body, somewhat embedded; greatest depth of body 6.3-7.4 in SL (Ref. 90102).
Occurs in the outer reef slopes; often found in pairs, hovering a few centimeters above the sandy bottom at the entrance to its burrow. Symbiotic with the red-and-white barred shrimp, Alpheus randalli (Ref. 40962).

): 24.7 - 28.9, mean 27.6 °C (based on 100 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00332 - 0.01511), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.2 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 (12 of 100) .
