A hypothetical or actual grouping of marine creatures, especially marine reptiles, that share whale-like body form characteristics.
From Latin 'cetus' (whale) + Greek 'morphe' (form, shape). A taxonomic or descriptive term for creatures with whale-like shapes.
Cetomorpha reminds us that biologists sometimes create categories based on body shape rather than evolutionary relationship—it's a useful concept but gets complicated when evolution produces similar shapes from completely different starting points.
