The 60 pages that link to Chondrichthyes, each with the reason it gives.

• SharkNarrower topic: Sharks belong to this broader group of cartilaginous fishes.

• Ray-finned fishCompared with: Cartilaginous fishes differ in skeletal composition and lack the characteristic ray-finned plan.

• FishBroader topic: Some species are eaten, though they differ from typical bony food fish.

• Swim bladderCompared with: Cartilaginous fishes generally lack the swim bladder found in many bony fishes.

• Ampullae of LorenziniNarrower topic: The organs occur in this fish group, especially sharks and rays.

• ActinopterygiiCompared with: Cartilaginous fishes provide a major comparison to the bony skeleton of actinopterygians.

• TeleostCompared with: Unlike teleosts, chondrichthyans have skeletons made primarily of cartilage.

• BoneCompared with: Their skeletons show that vertebrate support does not require a bony internal skeleton.

• OsteichthyesCompared with: Its members have predominantly cartilaginous skeletons rather than the bony skeleton typical of osteichthyans.

• Whale sharkNarrower topic: Its skeleton is made primarily of cartilage, the defining trait of this fish class.

• Great white sharkNarrower topic: Its cartilaginous skeleton distinguishes the great white from bony fishes.

• TeleosteiCompared with: Cartilaginous fishes contrast with teleosts in skeletal composition and many aspects of anatomy.

• Lobe-finned fishCompared with: Their cartilage-based skeleton contrasts with the bony fin supports of lobe-finned fish.

• Manta rayNarrower topic: The manta ray’s lightweight cartilage skeleton places it among sharks and other rays.

• Fish anatomyCompared with: Its skeletal material contrasts with the bony framework of most familiar fishes.

• Jawless fishCompared with: Cartilaginous fishes show that having jaws does not require a bony skeleton.

• Bony fishCompared with: Their cartilage-based skeleton contrasts with the substantial bone characteristic of bony fishes.

• ElasmobranchiiNarrower topic: Elasmobranchii is one of the two major living groups within this broader class.

• Marine fishBroader topic: Sharks, rays, and chimaeras are marine fish with a distinct skeletal lineage.

• SkateNarrower topic: Skates belong to this vertebrate group, alongside sharks and rays.

• Basking sharkNarrower topic: Its skeletal structure reflects the shared body plan of sharks and their relatives.

• ChimaeraNarrower topic: This broader fish group provides chimaeras’ evolutionary and anatomical context.

• AgnathaCompared with: Cartilaginous fishes have jaws, separating them from the jawless forms grouped as Agnatha.

• PlacodermCompared with: Their largely cartilaginous skeleton contrasts with placoderm bony armor.

• SawfishNarrower topic: Like other rays and sharks, sawfish have a cartilaginous skeleton.

• BatoideaNarrower topic: Batoidea is one of the two major living lineages within this class.

• Electric rayNarrower topic: Electric rays belong to this broader group of fishes.

• Fish finCompared with: Sharks and rays have fins supported by cartilage and dermal structures rather than typical bony rays.

• GnathostomataBroader topic: These living jawed vertebrates retain skeletons made primarily of cartilage.

• IchthyologyBroader topic: Their anatomy contrasts with the bony skeletons of most other fishes.

• John Edward GrayNarrower topic: Gray also classified cartilaginous fishes in his zoological work.

• Dermal denticleNarrower topic: Dermal denticles are characteristic of this vertebrate group.

• Nurse sharkNarrower topic: Like other sharks, the nurse shark has a cartilaginous skeleton.

• AcanthodiiRelated: Acanthodians share evolutionary connections with the lineage that includes living cartilaginous fishes.

• Goblin sharkNarrower topic: Like other sharks, the goblin shark has a cartilaginous skeleton.

• Greenland sharkNarrower topic: Its shark anatomy belongs to this broader vertebrate group.

• GuitarfishNarrower topic: Guitarfishes belong to this class, alongside sharks and other batoids.

• WobbegongNarrower topic: Like all sharks, wobbegongs have cartilaginous skeletons.
