Fish Coloring Worksheets
Fish are vertebrates that live in water (vertebrates means which have backbones). They breathe through their gills rather than their lungs, and their bodies are normally protected by fins and scales. They have a protective braincase as well as a visible head region with eyes, teeth, and other sensory organs.
Some of the smallest and largest fish in the sea include the cyprinid fish (8mm) and the whale shark (12m). There are almost 27,900 species of fish alive today, living in marine and freshwaters, at temperatures ranging from 0.3 inches/8 mm to 39 feet/12 m, and in settings as hot as 104°F/40°C and as cold as 28°F/-2°C.
Some of them have distinguishing features. Hagfish, for example, are not vertebrates and do not have scales; mudskippers may live outside of the water; lungfish breathe through their lungs; lampreys do not have paired fins; and tuna are warm-blooded!
