Do Sturgeon Fish Have Bones

Paddlefish family Polyodontidae are basal Chondrostean ray-finned fish.

Do sturgeon fish have bones. The cartilage bones take the place of regular bones throughout the body. The body of the Lake Sturgeon is made up of bony cartilage that is covered with slimy feeling skin. It is made mostly of cartilage but it is still classified as a bony fish.

Their spine is made of a coiled cartilage. With a broad flattened head tiny eyes and shark-like tail is well adapted for feeding on animals found below him. The white sturgeons overall body shape is long and cylindrical with the color on the back a brown or grey and the color on the bellies a gleaming white.

The arrow represents the direction of evolution. Sturgeon bodies are a combination of bones and cartilage but most of their body is cartilage like the tip our nose or our ears. They are a dark shade of brown at the top light brown in the middle and then sandy or cream colored along the belly.

The White Sturgeon while extremely large and tough does not actually have many bones. Most famously though sturgeon are the source for the symbol of decadent living. In fact the vertebrae of Sturgeon are not ossified made into bone and all the parts you see are in fact cartilage.

Sturgeons have bony plates scutes covering the head and five longitudinal rows of similar plates along the body. Sturgeons are anadromous migrating from freshwater to salt water and back like our local salmon. The skeletal structure of the Sturgeon is made up almost completely of cartilage and cartilage plates called scutes.

The body uses minerals to perform many different functions -from building strong bones to transmitting nerve impulses-. As is true for many long-lived species pallid sturgeon reach reproductive maturity relatively late. Cut as close to the bone as possible.
