What are the whiskers on a loach for?
- to court
- To protect oneself from enemies
- To search for food
See the answer
To search for food
When it comes to fish with impressive whiskers, loaches and catfish come to mind. Those whiskers are their trademark, but they’re actually very handy for finding food! They use their long whiskers to catch fish hiding in the mud.
What role do the whiskers attached to loaches and catfish serve?
- To intimidate the enemy
- To search for food
- To get in touch with my teammates
See the answer
To search for food
Loaches and catfish are notable for their impressive whiskers. Because loaches live in places where the water flow is gentle and mud easily accumulates, their eyes aren’t very useful, so they compensate by using their whiskers in place of sight. They quickly suck in anything that touches the tips of their whiskers and prey on it.
