Etymology: Acentrophryne: Greek, 'a' = without + Greek, 'kentron' = prickle or spine + Greek, 'phryne' = toad (highlighting the single most important distinguishing feature of this genus: the absence of a preopercular spine) (Ref. 86949).

توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
شعاع نرم باله پشتي (کل) : 3; شعاع نرم باله مخرجي: 3. Diagnosis: Metamorphosed females of Acentrophryne longidens differ from A. dolichonema in having a much shorter distal escal appendage (2.3-2.5% SL vs. 27.6-35.7% SL); a shorter illicium (35.7-54.9% SL vs. 63.6-70.5% SL); a wider head (35.7-37.3% SL vs. 25-28.1% SL); and a greater number of pectoral fin rays (18-19 vs. 16) (Ref. 54827); caudal fin rays 9, ninth ray (ventral most) 18.6-22.6% SL (Ref. 86949).
Body shape (shape guide): short and / or deep; Cross section: oval.
