in zoology, one of two principal body types occurring in members of the invertebrate animal phylum Cnidaria. It is the typical form of the jellyfish. The medusoid body is bell- or umbrella-shaped. Hanging downward from the centre is a stalklike structure, ... We do not support the media type you are attempting to upload.

One of the noticeable differences between vertebrates and invertebrates is their size. Invertebrates such as worms, shellfish, and insects are small and slow moving because they lack effective ways to support a large body and the muscles need to power it. ...

Ecosystem-wide body-size trends in Cambrian–Devonian marine invertebrate lineages ... Combined with known environmental changes during this interval, and especially records of carbon dioxide, these trends provide support for the claim that primary productivity increased during the early to mid Paleozoic.
