What does グパ mean?


There is a sound グパ in this manga (a plant tries to eat someone and makes グパ
sound), but I can't find it in dictionaries and understand what it means and
how it can be translated. What does グパ mean? Is it just something like
"A-a-a"?

This is a mimetic word that describes the wide opening of a mouth or "a mouth-
like thing". Sometimes it also describes how a covering/husk is cracked, like
a watermelon or a human head cracked by an axe.

The better-known variant is unvoiced くぱぁ, which was popularized in the last
two decades or so, and clearly has a sexual connotation (google it yourself;
NSFW). Voicing of く [makes it sound
"rough"](https://japanese.stackexchange.com/a/54142/5010), and it also avoids
the sexual connotation.

I'm sorry, I don't know how this is translated into English...
