Before that they were known in English as a haye or dogfish, which means sometime in the ~1400s enough English sailors started saying \u201cdon\u2019t get in the water, it\u2019s infested with those jerks\u201d
[Image description: Text that reads as follows:
The etymology of the word shark is uncertain, the most likely etymology states that the original sense of the word was that of \u201cpredator, one who preys on others\u201d from the Dutch schurk, meaning \u2018villain, scoundrel\u2019 (cf. card shark, loan shark, etc.), which was later applied to the fish due to its predatory behaviour.

fun fact: in german der Schurke / die Schurkin are villains, while der Hai is the predatory fish.
