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.
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. Ctenoid scales are similar to cycloid scales, also having growth rings, lack enamel, dentin, and a vascular bone layer. They are distinguished by spines or ...
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]
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.
Saxatilia differs from Hemeraia in the scaling of the sides of the body, which in Saxatilia consists predominantly of ctenoid scales, whereas in Hemeraia it is mainly cycloid scales. In contrast to Hemeraia and Teleocichla , in Saxatilia the infraorbitals 4 and 5 (bones below the eye socket) are not fused together.
They have a rounded head and a terminal mouth, although the snout hangs a little bit over the mouth. The dark coloring on the edges of the scales cause a cross-hatched look along the body. The scales on these fish are cycloid scales, a type of leptoid scale. It is possible to find the age of a fish from the rings on the scales.

The bowfin (Amia calva) is a ray-finned fish native to North America. Common names include mudfish, mud pike, dogfish, grindle, grinnel, swamp trout, and choupique.It is regarded as a relict, being one of only two surviving species of the Halecomorphi, a group of fish that first appeared during the Early Triassic, around 250 million years ago.
