Chondrichthyes: Fish with jaws, paired fins & an endoskeleton made of cartilage.

Cephalochordata: Fish with jaws, unpaired fins & an endoskeleton made of bone.

Lungfish: Lobe-finned fish with lungs & sturdy, jointed bones in its paired fins. ?

Actinopterygii: Fish with jaws, paired fins with rays & an endoskeleton made of bone.

Urochordata: Swimming larvae have notochords, but sessile adults are invertebrates.

Solutions

Expert Solution

Answer: Cephalochordata: Fish with jaws, unpaired fins & an endoskeleton made of bone.

Explanation: Cephalochordates are not fish but fish like animals. They have notochord and muscles are in segments.

- They have pharyngeal gill slits like fish and are considered the closest relative to fish (vertebrates).

Correct match Explanation:

- Chondrichthyes are also called as cartilaginous fishs. They are fishes with jaws and have paired fins, nares. As the name goes their skeleton is made up of cartilage.

- Lungfish have lobed fins. As the name goes they have highly specialized lungs. They bones are joined to a single bone.

- Actinopterygii are also called as ray-finned fishes. They are called so as they have paired fins with rays. Their endoskeleton is made up of bone rather than cartilage.

- Urochordata are also called as tunicates. They are invertebrates. Their larva is like a tadpole and has notochord. But as they develop the notochord becomes absent in the adults. Hence adults become invertebrates and are rounded and sessile.
