Description
Dorsal spines (total): 7; Dorsal soft rays (total): 13; Anal spine: 1; Anal soft rays: 13; Pectoral fin rays: 19-20 rays; Pelvic fins joined only at base, no pelvic frenum. Lateral scales series: 70-72; Transverse rows of scales backwards: 23-24; Nape scales reaching forward to rear edge of preopercle; Body scales cycloid anteriorly, becoming ctenoid below ~5th spine of first dorsal fin. Low basal membrane joins pelvic fins; Predorsal scales extending forward to above posterior margin of preopercle; Greatest depth of body: 5.2-6.7 in SL; Caudal fin: 2.8-3.6 in SL. Max. length: 9.0 cm TL. Depth range: 6 - 40 m.
Color
Head and body whitish, with 6 narrow oblique brown to orange-brown bars, anteriormost bar crossing head over preopercle narrowest, sometimes broken, and usually darker than other bars; Upper half of body with scattered irregular brownish spots and short streaks in interspaces between oblique bars; Thin blackish stripe curves through eyes onto snout tip.
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.
diagonalis: from Ancient Greek, diagṓnios = from angle to angle + from Latin suffix, -ālis = the suffix is added (usually, but not exclusively) to a noun or numeral to form an adjective of relationship to that noun. When suffixed to an existing adjective, the effect is and to intensify the adjectival meaning, and often to narrow the semantic field. Referring to the oblique bands on the body.
Original description: Amblyeleotris diagonalis Polunin & Lubbock 1979 - Type locality: 10-30 meters seaward east of South Island, Lizard Island, Great Barrier Reef, Australia, depth 25 meters.
Distribution
Red Sea; Indo-West Pacific: East Africa (Mozambique, Kenya), Persian Gulf, Seychelles and Madagascar, east to Philippines, New Ireland (Papua New Guinea) and Solomon Islands, north to southern Japan, south to Queensland (Australia) and New Caledonia.
Biology
Lives with symbiont alpheid shrimps which prepare and maintain burrows in sand or sand and rubble areas. Found in coastal to outer reef sand slopes.
