Description
Le gobie de Steinitz a le corps fuselé qui se rétrécisse vers la queue. Il est de couleur beige et strié légèrement en diagonale de 5 larges bandes marron. Ses yeux prohéminants cerclés de blanc et de noir sont situés très haut sur la tête. Les nageoires sont à peine visibles sauf les pectorales. Taille adulte 7 - 8 cm - Taille maximum 13 cm. Profondeur 5 - 30 m.
Biologie
La famille des gobies est la plus grande des poissons marins avec plus de 1.500 espèces. La plupart sont benthiques et vivent dans un terrier creusé dans le sable, en couple ou parfois en association avec une crevette qui entretien la galerie. Le gobie signale l'arrivée de prédateurs éventuels protégeant ainsi la crevette. Amblyeleotris steinitzi vit en association symbiotique avec des crevettes de la famille des Alpheidae (environ 600 espèces) en partageant son terrier. En mer rouge l'Amblyeleotris sungami ressemble à Amblyeleotris steinitzi.

Etymology
Amblyeleotris: from Greek, amblys or amblus = dull (blade: not sharp), blunt, obtuse + from the Greek name of a fish, eleōtris, found in the swampy waters of the Nile (Egypt) (from the Greek, eleios = who lives in the marshes). The name Eleotris appears for the first time in Déipnosophistes, a compilation of anecdotes and quotations from ancient authors, written by a scholar and grammarian Greek, Athenaeus of Naucratis (about 170-223 AD). In 1763, the Dutch naturalist and collector Laurentius Theodorus Gronovius (1730-1777) used this name to designate a new genus of fish. The authorship of the genre escapes him because his work was rejected by the scientific community of the time. The genre should have returned to the doctor, entomologist and naturalist of Italian culture, Giovanni Antonio Scopoli (1723-1788) but the late recognition of his work made him lose the authorship of the name. Today the genus, Eleotris, is attributed to Bloch & Schneider, 1801.
