Slender predatory greyish to yellowish-brown fishes becoming silvery below, with a yellow tail, a narrow pointed head, a large eye, a large mouth with a slightly protruding lower jaw, and a single row of small teeth in both jaws. The small first dorsal fin is widely-separated from the larger second dorsal, the anal fin is long-based, and the lateral line is almost straight and continues far onto the tail.
Longfin Pike are often seen hovering motionless in schools above the bottom, occasionally in their hundreds.
