stingrays are cartilaginous ..quick answer : Stingrays have no bones in their body
The stingrays are a family---Dasyatidae---of rays and are a cartilaginous fish related to sharks , cartilaginous fish are jawed fish and skeletons made of cartilage rather than bone. The skeleton is cartilaginous. The notochord--A flexible rod-like structure that forms the supporting axis of the body in the lowest chordates and lowest vertebrates and in embryos of higher vertebrates, which is present in the young, is gradually replaced by cartilage.
The class Chondrichthyes ( Cartilaginous fish) also lack ribs, so if they left the water, the larger species's own body weight would crush their internal organs long before they would suffocate.
since they do not have bones and therefore no bone marrow, red blood cells are produced in the spleen of cartilaginous fish as well as in special tissue around the gonads
Are hip and knee rotation inversely related?
Not sure I understand the question...
The hip and the knee can rotate to the same direction as well as in opposite directions, either bearing body weight or not bearing body weight.
As a side note, in Chinese martial arts the hips are frequently externally rotated and knees internally rotated simultaneously in order to produce tension in the legs.

To cut a rib eye roll, first ensure it's well-chilled for easier handling. Place the roll on a cutting board and identify the grain of the meat.

Trim any excess fat if desired, and your rib eye steaks are ready for cooking.

Talus is typically found at the base of steep rock faces, cliffs, or mountainous areas where weathering and erosion have caused fragmented rock to accumulate. It often forms in alpine environments, where freeze-thaw cycles break down larger rocks into smaller pieces. Additionally, talus can be present in areas with significant geological activity, such as fault lines or volcanic regions, where rock falls are common.
