简单描述
型态特徵 | 形态测量图
背棘 (总数): 7 - 8; 背的软条 (总数): 8-10; 臀棘 1; 臀鳍软条: 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).
鉴别: 这种有别于 T. adela Hoese&Larson, 1987, 在有一个方面较狭窄的鳃裂, 在眼后面在眼的后缘之下或些微地向前延伸到;(vs. 在眼的中央下面) 更不广泛地覆有鳞片的身体, 藉由延伸到第二背鳍起源下面的裸露区或超过;(vs. 第一背鳍的近末端) 比较高的横跨鳞片计数 (通常 7- 8 vs.6- 7); 典型低的脊椎骨数 (10+16 和 10+17 比较); 前面的鼻管明显长度超过在后部的鼻管;(vs. 几乎相等的) 第一个脉棘前的二个肛门的支鳍骨;(vs.1) 在尾鰭基底上的最上面的鱗片與最低的鱗片有增大的周邊 cteni 。 (vs. 沒有增大的周邊 cteni) 有一些色彩不同，包括: 沒有黑色的斑點在第一背鰭後面; 通常 5- 在尾梗的腹中線上的 6個小的黑色約略圓形的斑點;(vs. 通常 4 水平地延長黑色的斑點) 在基部的胸鰭中的第三上的一個寬的黑色或深褐色的區域 (vs. 沒有明顯的黑色區域或一個小的黑色斑點背面上近端的上面 2- 3個鰭條); 背鰭、臀鰭與尾鰭有薄的波浪狀的灰色線;(vs. 均勻著色的) 而且沒有第一背鰭前的在條紋上的深色的背面中央的線.(參考文獻 57647)
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).
观察是独居性的与可能地, 一个具有领域性种。 栖息于用洞，裂隙与小的洞穴打破岩礁; 部分在岩石的岩架上栖息泥沙或贝壳残砾的 overlain 。 报告时常用大很多的黑色鰕虎鱼 Gobiopsis atrata 被收集在水中的被分享的洞穴. 它的体型小，善于隐藏的习惯, 半-透明, 而且伪装颜色使这一个鱼非常困难设置在水中的; 虽然轻易地用毒鱼酮采集毒鱼剂了然而潜水。 在纽西兰的这种的栖息地是非常类似在澳洲的 T. adela, 是局限于岩礁, 常见于淤泥的混浊水域中, 在 1-24 公尺深。 可能是收集使用吃的聲音槍或者手收集了毒魚酮毒魚劑的下列受約束使用.(參考文獻 57647)
