Hello everyone, my name is Ivaan and I'm Dad. Welcome to my channel Facts with Ivaan. I'm in year one and every day I come across millions of new facts. Some interesting and some boring. On this channel, I show you some amazing facts.

Let's move to the fact of the day. Have you ever imagined how animals talk to each other? Today, let's understand how fish talk. The most common ways fish communicate are through sound, colour, motion, and smell. These are used to help pass through, call, alert, and even while fighting.

Three types of sound are generally used by fish to talk. Most of these sounds are inaudible to humans. Not all fish can produce sound, so they use body language or movement instead. Colour is the most developed form used by fish to communicate. Many fish can change the shade of their skin, some can glow, and even change their colours to talk. For example, bright colours are used by fish who aren't excellent swimmers to tell other fish to stay away.

Do you want to hear a silly fun fact? Fish also use their wee-wee to talk. A recent study found that some fish use their wee-wee to send signals and get their sensed messages across. That is silly.

That is all I have for today. Thank you everyone for listening. I'll see you all soon with some more facts.
