My pet budgerigar is very smart.

I'm thinking of making pepper steak for dinner tonight.

As the name suggests, the grey reef shark has a black tail and white eyes.

My boat is equipped with the latest fishfinder.

He found a way to profit from a difficult situation like fishing at the bottom of a river.

He was swimming freely as if he was a fish playing in the pot.

He is a person who follows his own path, and the phrase 'a big fish does not swim into a small stream' fits him perfectly.

He is truly demonstrating talent that surpasses his master, just as the saying 'the student has surpassed his or her teacher' goes.
