Blackchin shiners are highly abundant, small fish. These factors increase the likelihood that the blackchin shiner is a food source for juvenile northern pike (Esox lucius) and yellow perch (Perca flavescens), both of which are found in the same areas of Manitoba. [4]
A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages.
The scales on its body are composed of round lateral scales called cycloid scales. It has a slightly subterminal mouth and no adipose fin. Like other members of the family Cyprinidae, the pallid shiner is a toothless fish and has no stomach. Instead they chew their food using gill rakers on their gills and pharyngeal teeth. [6]
Loaches are popular in the aquarium trade. Loaches are fed sinking discs designed for them in the aquarium. Some of the most well-known examples are the clown loach (Chromobotia macracanthus), the kuhli loach (Pangio kuhlii), and the dwarf chain loach (Ambastaia sidthimunki). Botiid and gastromyzontid loaches also occasionally make their way ...
This species has very large cycloid scales, below which is a thick layer of fat. The swim bladder has two anterior projections that extend into the back of the skull, near the inner ear. [ 7 ] This fish lacks the median keel on the caudal peduncle – it only has the characteristic pair of small keels on each side of the base of the caudal fin ...
Reptile scale types include: cycloid, granular (which appear bumpy), and keeled (which have a center ridge). Scales usually vary in size, the stouter, larger scales cover parts that are often exposed to physical stress (usually the feet, tail and head), while scales are small around the joints for flexibility.
These scales cover the fish's body with little overlapping. They are typical of gar and bichirs. Cycloid scales are small, oval-shaped scales with growth rings like the rings of a tree. They lack enamel, dentin, and a vascular bone layer. Bowfin and remora have cycloid scales.
The princess parrotfish (Scarus taeniopterus) is a species of marine ray-finned fish, a parrotfish, in the family Scaridae. [2] It is typically 20 to 25 centimetres (7.9 to 9.8 in) long, found in the Caribbean, South Florida, the Bahamas, and Bermuda. [3]
