Does a stone fish is cartilagous fish?

No, a stonefish is not a cartilaginous fish; it is a bony fish. Stonefish belong to the family Synanceiidae and are known for their venomous spines and ability to camouflage with their surroundings. They have a skeleton made of bone, which distinguishes them from cartilaginous fish like sharks and rays that have skeletons made of cartilage.
