Etymology: Hypoplectrus: Greek, hypo = under + Greek, plektron = sting, spur (Ref. 45335).
More on author: Cuvier.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 3 - 23 m (Ref. 9710). Tropical
Western Central Atlantic: rare along the most of the continental western Caribbean, becoming occasional in the vicinity of Panama; Bahamas, Virgin Islands, Lesser Antilles, and islands off Venezuela. Absent from Florida, Marquesas Keys and the Dry Tortugas (USA); records from Texas, USA are almost certainly misidentified juveniles of Epinephelus sp.

Bayesian length-weight: a=0.01778 (0.00689 - 0.04588), b=3.03 (2.80 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.4 se; based on diet studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
