Etymology: Boleophthalmus: Name from Greek, ßo?? 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.. More on author: Linnaeus.
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; demersal; pH range: 8.0 - 8.5; non-migratory; depth range 0 - ? m. Tropical; 26°C - 30°C (Ref. 2060)
Northwest Pacific: China, Korean Peninsula, Japan and Taiwan.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 7 - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 2060); max. reported age: 4 years (Ref. 53358)
soft rays: 24 - 30. Distinguished by the following characteristics: Total elements in D2 23-26; caudal fin length 18.3-22.2% SL; head length 24.3-28.0% SL; length of D2 base 41.5-46.1% SL; first D2 element usually segmented and branched; longitudinal scale count 84-123; predorsal scales 26-48; lower jaw teeth notched (Ref. 5218).
An intertidal and amphibious air-breather that actively shuttles back and forth between tide pools and air (Ref. 31184). Creeps around and browses on mud flats at low tide; stays in a burrow in the mud at high tide. Herbivores that graze on diatoms on the mud surface during low tide (Ref. 92840). Caught for food. Used in Chinese medicine (Ref. 12166).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00543 - 0.01679), b=2.95 (2.80 - 3.10), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 2.0 ±0.00 se; based on food items.
Generation time: 1.0 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=4).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
