Random Q: which fish got proportionally the biggest jaws?

Hi guys,
Do you have any idea of which freshwater fish got the biggest jaws relative to their body size? All I can come up with is either the RT catfish or silver arowana...

 

Are we talking about ones that can be kept in an aquarium? If not, then the arapiama (spelling) or alligator gar would be my guess.

 

Oops its aquarium fish.

 

Maybe the Peacock bass ? There are fish which mouth act liked vacuum cleaners by making enlarging its mouth it creates a vacuum effect (I don't know their names)

 

My suggestion would be the arowana and the clown knife fish as the ones with a misleading mouth size vs size of fish..........well you gotta see them eat then you will know

 

African Butterfly fish must be up there with them

 

Compressiceps, Arowana, Pengasius Catfish and Stingrays. Not talking about BL fish though. But I think very fiew freshwater fish mouth vs body size compares to a Bass.

 

Large Mouth Bass? Stretched out the mouths on those guys really get big!

 

Any filter feeding fish, IMO. Look at basking sharks, paddlefish, whale sharks... all have massive mouths! The same goes for many deep sea fish, as it's a necessity!

For a real treat, look up the slingjaw wrasse on Google Images. Madness. The closest fishwater counterpart I can think of to that is the South American leaf fish. Very bizzare but all for a purpose.
