Redside dace

Description

The redside dace (Clinostomus elongatus) is a species of ray-finned fish in the family Cyprinidae,found in the United States and Canada.It is unique among minnows,being the only species to routinely feed on flying insects by leaping from water.Thus,it acts as a conduit for nutrient transfers between terrestrial and aquatic environments.The species can be used as an ecosystem health indicator,as it is sensitive to environmental disturbances.The redside dace is brightly coloured,with a wide red stripe extending from the head to the dorsal fin,running along the middle of the body.Above it,a bright yellow stripe extends from head to tail.Colours are the brightest during spring,gradually fading during late summer and fall.Distinguishing it from other cyprinids,the species has a very large mouth and protruding lower jaw,which is an effective adaptation for capturing prey from below.The species' maximum length is 12 cm.The lifespan is no longer than four years.It has longer and more slender body with brighter red coloration on its sides than the similar rosyside dace.
