Etymology: Clarias:Greek, chlaros = lively, in reference to the ability of the fish to live for a long time out of water; sulcatus:Derived from the Latin sulcatus, meaning furrow, in reference to the shape of the front fontanel.
Environment: milieu / climate zone / 深度上下限 / distribution range 生态学
背棘 (总数) : 0; 背的软条 (总数) : 72 - 80; 臀鳍软条: 56 - 64; 脊椎骨: 62 - 64. Distinguished from Southeast Asian congeners, except Clarias batrachus and C. insolitus in having a narrow frontal fontanel. Differs from C. batrachus in possessing more anal-fin rays (56-64 vs. 47-58) and a broader snout and from C. insolitus in having a wider head (17.4-18.3% SL vs. 14.0-15.6) and a smaller distance between the occipital process and the dorsal fin (7.2-7.5% SL vs. 10.3-12.4) (Ref. 55369). Body shape (shape guide): elongated. 与东南亚同类区分了, 除了 Clarias batrachus 与 C. insolitus 以外在有一个方面狭窄的前囟门。 在持有更多的臀鳍棘条 (56-64 vs.47-58) 与一个比较宽的吻方面有别于 C. batrachus 与从 C. insolitus 在有一个方面比较宽的头部 (17.4-18.3% SL vs.14.0-15.6) 与一比较小的后头骨的突起与背鳍 (7.2-7.5% SL vs.10.3-12.4) 之间的距離.(參考文獻 55369)
