Etymology: Boleophthalmus: Name from Greek, ßoƛɛ for ejected and 'ophthalmos' for eye; refers to species capability to rapidly raise their eyes above the level of their orbital cavities, as if the eyes were being ejected..

Estimates based on models
Preferred temperature (Ref. 115969
): 25.4 - 29.2, mean 28.4 °C (based on 1050 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00316 - 0.01588), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
