Etymology: Eucyclogobius: Greek, eu = good + Greek, kyklos = circle + Latin, gobius = gudgeon (Ref. 45335). More on author: Girard.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; demersal. Subtropical
Eastern Pacific: Del Norte County in northern California, USA to Del Mar in southern California.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 3 - 2.7 cm
Max length : 5.7 cm TL male/unsexed; (Ref. 2850); common length : 4.3 cm TL male/unsexed; (Ref. 12193); max. reported age: 1.00 years (Ref. 26474)
Inhabits coastal lagoons and brackish bays at mouth of freshwater streams (Ref. 2850). IS subjected to wide variation in salinity (1-28 ppt.) and temperature (9-25°C) both within and among habitat types. The substrate and vegetation can also differ among lagoon, creek and marsh habitats (Ref. 26474). Feeds mainly on crustaceans, dipteran larvae, gastropods, and invertebrate eggs (Ref. 26474). Oviparous (Ref. 56079). Males construct nesting burrows (Ref. 56079).

Oviparous (Ref. 56079). Eggs are brooded in nesting burrows constructed by males (Ref. 56079).

Bayesian length-weight: a=0.00692 (0.00310 - 0.01545), b=3.02 (2.83 - 3.21), 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 diet studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (tmax=1).
Vulnerability (Ref. 59153
