توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 21 - 24; شعاع نرم باله پشتي (کل) : 12 - 13; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 24 - 26. Pale to dark greyish-green in color, breaking up into four broad saddles on the body with pale green and white between. Belly white. Fins dark mottled olive-green. Distinguished from other triplefins by its large size and rounded bulbous head, the lateral line which is continuous to the caudal peduncle and rows of large recurved teeth in the jaws.
Adults prefer exposed reefs and deeper pools. Also found in rock pools (Ref. 9003). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114). B. dorsalis is the largest known triplefin species and the only fish predator in the family (Ref. 13227).
