The kitefin shark or seal shark (Dalatias licha) is a species of squaliform shark in the family Dalatiidae, and the type species in its genus. It is found sporadically around the world, usually close to the sea floor at depths of 200–600 m (660–1,970 ft).
The Dalatiidae are the family of kitefin sharks of the order Squaliformes (the term "kitefin shark" also refers specifically to the species Dalatias licha). Members of this family are small, under 2 m (6.6 ft) long, and are found worldwide.

It's "extremely unusual" for two bite incidents to occur in one afternoon, Crawford said during an evening news briefing. A 45-year-old woman was injured in the first "reported shark incident."
Anti-predator adaptation in action: the kitefin shark (a–c) and the Atlantic wreckfish (d–f) attempt to prey on hagfishes. First, the predators approach their potential prey. Predators bite or try to swallow the hagfishes, but the hagfishes have already projected jets of slime (arrows) into the predators' mouths.
Echinorhinidae are traditionally classified in the order Squaliformes, together with kitefin and gulper sharks. [2] [3] However, a phylogenetic estimate based on gene capture data and mitochondrial data suggests that they are not squaliform sharks, but may be more likely to be appropriately classed in their own group, as a sister group to angel sharks and sawsharks.
The first shark bit him in the knee. The second shark bit him in the shoulder. But somehow, Marlin Deere Wakeman was able to pull himself out of the water and into a boat.
