Do fish sleep?

Even though they always appear to be awake and moving, fish DO sleep. They don’t have eyelids to close their eyes like we do, but fish do slow down and will appear to be zoned out. Fish don’t go in to a deep sleep like humans do, but their bodies and metabolisms have periods throughout the day when they are not as active as others. Some fish must keep moving to ventilate their gills, while others may lay down on a leaf or rock to catch their zzzz’s.

What’s the world’s largest/smallest fish?
The largest fish in the world is the whale shark, which grows to over 50 feet in length. The title of smallest fish goes to the Philippine goby, measuring in at 1/3 of an inch.

Do fish feel pain?
Fish CAN feel pain, just like humans. This seems obvious, but until recently many experts were unsure. Fish have all of the same senses that we have, along with their lateral line organ that gives them an extra radar like sense to process their surroundings.

Fish are often thought of as silent, but many fish can make noises by grinding their teeth or squeaking their swimbladders. Catfish are known to croak when pulled from the water, and sound similar to a frog.

Fish exist in more than just our waters. Many common products we use every day contain fish or fish parts. Lipstick contains fish scales and there are clothing lines made entirely from crab shells. And how do you get rid of that nasty morning breath? Brush your teeth using toothpaste, which contains, you guessed it – fish!
