Solution

pomfret

Explanation:

In Peripatus, characters like segmented body, thin cuticle, and parapodia-like organs are present. Similarly, duck-billed platypus lays eggs like reptiles but shows relationships with mammals too due to the presence of mammary glands and hairs. Lungfish perform respiration with lungs, irrespective of being fish. These examples indicate that mammals are evolved from reptiles and amphibians from fish.
