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

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

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

• 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.

• 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.

• 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.

• 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.

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

• CyclostomiCompared with: Cartilaginous fishes show that a flexible skeleton does not imply membership in Cyclostomi.
