The trumpetfish is a sneaky predator.



The trumpetfish is a sneaky predator. It will sometimes swim slowly and sneak up on its prey, or it may act like a floating stick. This predatory technique likely became part of the trumpetfish’s instinct after the Fall when animals began to eat other animals.


  • This fish is extremely long and slender.
  • It also has a long, tube-like snout into which it sucks its prey.
  • The trumpetfish’s color varies from dark brown to green.
