Etymology: Wallago: wallago;Bleeker, in 1851, took the Indian fish name, gave it generic range and used it connection with a new species. The name is "walaga" in Telugu / Tamil (Ref. 45335).
Eponymy: Lieutenant-Colonel J M van Leer was a Dutch army physician who was a colleague of Bleeker’s. He was for a time the Directing Surgeon at Samarang, East Sumatra. He provided the holotypes of these species. (Ref. 128868), visit book page.

簡短描述 檢索表 | 型態特徵 | 形態測量圖

背棘 (總數) : 1; 背的軟條 (總數) : 4; 臀鰭軟條: 60 - 75. Differs from all other congeners by having a jet black pectoral-fin membranes. Branchiostegal rays 15-18 (Ref. 2091). Corner of mouth reaching only to anterior margin of eye (Ref. 7050).
嘴只對眼的前緣達到; 顎骨觸鬚短於腹鰭.(參考文獻 12693)

生物學特性     字彙 (例如 epibenthic)

Adults inhabit large streams and rivers (Ref. 12455). Fry occur at the mouth of small streams connected to larger rivers, where the bottom is muddy and with overhanging vegetation (Ref. 56749). Feeds on prawns (Ref. 56749). Oviparous, distinct pairing possibly like other members of the same family (Ref. 205). Fishermen along Kapuas in Indonesia observed that it used to form large migratory schools in Kapuas mainstream but such schools had become less noticeable, and this was attributed to intensive gill netting. Usually consumed fresh or processed as salted fish (Ref. 56749). Reaches more than 150 cm TL (Ref. 7050).

成魚棲息於大的溪流與河 (參考文獻 12455) 而且進入被水淹沒的森林。 (參考文獻 9497) 在魚上的一個夜行的掠食者.(參考文獻 12693) 卵生的, 明顯的成對可能地像其他的相同該科的成員.(參考文獻 205) 在湄公河中，這種游進內較小的溪流到產卵.(參考文獻 37770) 卡普阿斯河的漁夫觀察它用來.形式大的迴游群游於卡普阿斯河主流但是如此的魚群已經變得比較不易見，而且這被歸因於密集的刺網。
