Etymology: Limnichthys: Greek,limne = swamp + Greek, ichthys = fish (Ref. 45335). More on author: Waite.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated. Tropical
Western Pacific: Japan to Australia and the Kermadec Islands. Recently reported from Tonga (Ref. 53797).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.0 cm TL male/unsexed; (Ref. 2334)
soft rays: 22 - 40. Body fully scale. At least some of the dorsal saddles reaching a distinct lateral band. Combined number of soft rays in dorsal and anal fins usually 49 to 55 (Ref 12874).
A cryptic species that occurs on sandy or gravel bottoms. Pointed snout is used for burrowing; eyes directed upwards for sighting prey. Found from shallow tide pools to at least 150 m (Ref. 2334). Eyes move independently and possess a refractive cornea, a convexiclivate fovea and a non-spherical lens (Ref. 50869). Neither cleitheral spine gland nor anterolateral glandural goove with gland is present (Ref. 57406).
