Fun Cutlips Minnow Facts For Kids
Gallery
The cutlip minnow belongs to the Cyprinidea family of freshwater fish (minnow). It can grow to be around 6.3 in (16 cm) long.
It is a medium-sized minnow. Its robust body, silvery sides with a greenish-purple sheen, and tri-lobed lower mouth set it apart from all other fish species.
It may be differentiated from other minnow species in Canada, North America by its trilobed lower mouth.
This species is seen near the northern end of its distribution in Ontario, where it is found in the lower Ottawa and St. Lawrence River drainage regions. Because there has been little study on the cutlip minnow, it is impossible to say whether the species is in decline.
Recent studies show that the cutlip minnow has vanished from certain historic locations, but new, low-abundance populations have been discovered in the St. Lawrence River and its tributaries, suggesting that the species' condition is stable.

Mature male minnows prefer to build their nests on the undersides of horizontal surfaces like rocks, wood, or plants. A male minnow conducts a variety of mating activities in order to attract female minnows to his nest.
When approaching adult female minnows, the male will swim back and forth in the nest region, establish close contact with passing females, and vibrate his body. Fertilized eggs are then laid in a single layer on the ceiling of the nest location. Male minnows are solely responsible for the care of the eggs.
They use their dorsal pad to clean the eggs and fan the nest eggs to ensure the unborn minnows get enough oxygen. The eggs hatch after roughly a week.

This species' range extends from St. Lawrence and Lake Ontario south into Virginia and is categorized as Least Concern by the IUCN Red List. Though it is categorized as threatened in the Canadian province of Ontario, but it may never have been widespread there because it is located in the far north of its range.
