Eels do not have cartilaginous bones; instead, they possess a skeleton made primarily of bone. Most eels belong to the order Anguilliformes and have a bony structure, although some species within the broader category of fish, like sharks and rays, do have cartilaginous skeletons. Eels exhibit a unique body structure that allows them to be highly adaptable in their aquatic environments.
No, it has a skeleton of bone.
benign outgrowth of cartilaginous tissue on a bone
Cartilaginous fish, also known as elasmobranchi, have skeletons made of cartilage rather than bone. Bony fish, also known as teleosts, have skeletons made of bone.
The skeleton is originally cartilaginous during fetal development. Over time, the cartilage is replaced by bone in a process called endochondral ossification, where bone tissue gradually forms and replaces the cartilage framework.

Eels are fish, and fish have a skeleton. Note, however, that the skeletons of fish are not composed of "bone" as we know it, but of cartilage.
No they are cartilaginous fish, meaning that they have cartilage instead of bones for their skeleton.
One example of a cartilaginous fish is the shark. Sharks have skeletons made of cartilage rather than bone, distinguishing them from bony fish, which have skeletons made of bone.
Sharks belong to cartilaginous fish. (Chondrichthyes)
