Short description সনাক্তকারী নির্দেশক | বহিঃ অঙ্গ সংস্থান | মরফোমেট্রিক্স

পৃষ্ঠীয় কাঁটা (মোট ) : 7 - 8; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 8 - 10; পায়ূ কাঁটা : 1; পায়ূর নরম পাখনা্তুন্ড: 7 - 9. Diagnosis: This species differs from T. adela Hoese & Larson, 1987, in having a narrower gill opening, extending forward to below posterior margin of eye or slightly behind eye (vs. under middle of eye); less extensively scaled body, with naked area reaching to below second dorsal origin or beyond (vs. near end of first dorsal fin); higher transverse scale count (usually 7 - 8 vs. 6 - 7); modally lower vertebral count (10+16 vs. 10+17); anterior nasal tube distinctly longer than posterior nasal tube (vs. subequal); two anal pterygiophores before first haemal spine (vs. 1); uppermost scale and lowermost scale on base of caudal fin with enlarged peripheral cteni (vs. no enlarged peripheral cteni). There are several color differences, including: lacking a black spot posteriorly on the first dorsal fin; usually 5 - 6 small black more or less rounded spots on the ventral midline of the caudal peduncle (vs. usually 4 horizontally elongate black spots); a broad black or dark brown area on basal third of pectoral fin (vs. no distinct black area or a small black spot dorsally on proximal upper 2 - 3 rays); dorsal, anal, and caudal fins with thin wavy grey lines (vs. uniformly pigmented); and no dark dorsomedian line on band before first dorsal fin (Ref. 57647).

জীববিজ্ঞান     শব্দকোষ (উদাহরণ স্বরূপ epibenthic)

Observed to be solitary and possibly, a territorial species. Inhabits broken rocky reefs with holes, crevices, and small caves; perches on rocky ledges partly overlain by silty sand or shell debris. Reported to be often collected underwater sharing caves with much larger black gobies Gobiopsis atrata. Its small size, cryptic habit, semi-transparency, and camouflage coloration make this fish very difficult to locate underwater; though readily collected with rotenone ichthyocide while scuba diving. The habitat of this species in New Zealand is very similar to that of T. adela in Australia, which is restricted to rocky reefs, often in silty turbid waters, at 1-24 m depth. May be collected using slurp gun or hand collected following controlled use of rotenone ichthyocide (Ref. 57647).
