簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 7 - 9; 背的軟條 (總數): 14-16; 臀棘 0; 臀鰭軟條: 10 - 13; 脊椎骨: 32 - 33. Distinguished by the flattened tripartite anal papilla and the cirri on the eyeballs, head, lateral line and at the tip of each dorsal spine (Ref. 27547). Gill rakers reduced to low smooth mounds; lateral line high toward the head, curving downward to middle of sides, straight toward the tail, each of the anterior 15 or so pores having a slender cirrus (Ref. 27547). Next to the last anal ray longer than the rays before and behind it; pectorals reach to or just beyond front of anal fin; caudal rounded (Ref. 6885, 27547). Color varies with the environment, sometimes nearly uniform bright green but more often green to light brown above with dark wedge-shaped saddles, broader below, on upper part of sides, with lighter color between; sometimes, along or below lateral line, a dark longitudinal stripe that is in some cases interrupted with light spots; ventral region creamy to white; three dark lines radiating from the eye, the first to the snout, another downward to behind the mouth, the third rearward to base of preopercular spine; spiny dorsal with a dark blotch between first and third spine; pelvic fins plain, others usually dusky, mottled or indistinctly barred (Ref. 27547).
在眼球,頭部上區別的特徵為平的三裂肛門的乳突與觸鬚了, 側線而在每個背棘的頂端。 (參考文獻 27547) 鰓耙縮小成低的平滑堆了; 側線高度地朝向頭部, 彎曲的向下對側邊的中央,直線朝向尾部,被有一個細長的卷鬚的每一個前面 15 左右的孔.(參考文獻 27547) 緊鄰著最後的臀鰭鰭條長度超過鰭條在與之前在它後面; 胸鰭達到到或正好超過臀鰭前面; 尾鰭圓的.(參考文獻 6885,27547) 顏色隨著環境改變, 有時幾乎均勻明亮的綠色但是更時常綠色到背面淡褐色的有深色的楔形鞍狀斑, 比較寬的在下面, 在側邊的上半部上, 藉由較淡的顏色在;之間 有時, 沿著側線或在其下方, 一條深色的縱向斑紋在一些情況,那是以淡色的斑點中斷; 腹面區域乳脂色的到白色; 三個黑色線條放射從眼,吻部的第一個, 另外向下的在嘴巴,前鰓蓋骨棘的基底的第三後方後面; 刺狀的背部有在第一個與第三根棘之間的一個黑色斑塊; 腹鰭無花紋的, 其它通常暗色的, 有斑點的或模糊地條紋.(參考文獻 27547)

生物學特性     字彙 (例如 epibenthic)

Commonly found in rocky intertidal and subtidal areas, but also over sand and in eelgrass and seaweeds (Ref. 2850). May leave tide pools if aquatic conditions become inhospitable (Ref. 31184). Occasionally enters fresh water (Ref. 27547). Probably feeds on small invertebrates common among seaweed and in tide pools. Breathes air when out of water (Ref. 31184).

普遍地棲息於岩石的潮間帶與亞潮帶區, 也在沙子之上與在鰻草與海草中.(參考文獻 2850) 如果水生的環境變成不適居留,可能離開潮池。 (參考文獻 31184) 偶然地進入淡水。 (參考文獻 27547) 可能吃小型無脊椎動物普遍在海草之中與在潮池中。 呼吸空氣當離開水面.(參考文獻 31184)
