АКУЛА [akúla] 'shark'. Recorded in dictionaries (originally with -kk-) since 1789, but known earlier, probably from Sc. languages, cf. OSc. hakarl (with -a in R. perhaps by analogy with рыба 'fish') alternately from a Norw. dial. source, cf. also Farøese hakallur 'basking shark', hákelling 'Greenland shark', Icel. hakka 'to eat like a beast'.
