Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 1 - 2 m (Ref. 5981). Subtropical
Northeast Atlantic: off Portugal; also in the Mediterranean Sea.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.8 cm TL male/unsexed; (Ref. 59099)
Facultative air-breathing (Ref. 126274); Adults occur on filamentous algae-covered rocky terraces; occasionally in brackish water (Ref. 5981). Predominantly active during sunlight; otherwise found in piddock holes or barnacle shells (Ref. 5981). They feed on benthic meiofauna, especially harpacticoids; also algae (Ref. 5981). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
