This what Pike said on the topic,"

Well if I read what reasons it gets called "化け鮫" it looks most fitting to say "Corrupted/化け Shark/鮫" since it says it has to do with its weird frog like and fast tranformations from larva to young adult.

"化け" = "Garbage", "Corrupted", "Garbled" or "Scrambled". To take it to english id just say Mixed up, Messed up or a mix of both basically. Hope that helps."
