Vertebrae 12 + 25-27. Orbital cirrus simple and slender, may have a short lateral branch, less often up to 4 branches; nasal cirri short and palmate, may rarely have more than 6 branches; nuchal cirri simple and slender, may have a single branch or a ragged edge. Mandibular pores 6. Dorsal lips margin entire, ventral margin crenulated. Occipital crest absent, but large males have a low thin ridge (less than 1.8 mm); no crest or ridge in females Three color-pattern types described for different localities (see Ref. 9962). Body of males with 6-7 dusky bands with 1 or a pair of dark margined, pale, oblong spots on each band; dark spots on spinous dorsal, dusky lines on rayed dorsal. Females with spots on caudal peduncle; body sometimes with fine dark specks (Ref. 4404). Body depth at anal-fin origin 4.6-5.3 in SL (Ref. 90102).

生物學特性     字彙 (例如 epibenthic)

Adults inhabit exposed outer intertidal reef flats, where it can hide in cracks and holes. Commonly observed clinging to rocks as the water recedes below them during the low cycle of the swell and this species is often confused with mudskipper gobies (Ref. 48636). They feed on filamentous algae and associated small invertebrates, such as foraminiferans, ostracods, copepods, and gastropods. 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). Rarely used for aquarium fish.

棲息於裸露的潮間帶外圍礁石平臺, 在那裡它能藏在裂縫與洞中。 通常觀察附著於岩石當海水消退低於他們海浪週期低點期間與這種時常與彈塗魚互相混淆.(參考文獻 48636) 吃絲狀藻類與伴隨的小型無脊椎動物例如有孔蟲,介形蟲,橈腳類的動物與腹足動物。 卵生的.(參考文獻 205) 很少用來了水族館魚。
