•There are over 25,000 identified fish species & thought to be over 15,000 more!

•40% fish live in freshwater, but only .01% of earth covered with freshwater.

•Spotted climbing perch can hold oxygen enough to ‘crawl’ onto land.

Fish Facts:

•Some fish like sharks don’t have air bladders & must swim constantly or fall to the bottom.

•Some make sounds by grating teeth or swim bladder.

•Some species can fly (glide), skip along the surface, or ‘crawl’ up rock.

•Some fish have a special organ that acts like a ‘radar’ to see in dark/murky water.
