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
