Segmentverma

Segmentverma is a clade that contains animals with a spine and many types of invertebrates. They are defined by a long length-spanning central nerve.

All segmentverma exhibit [//en.wikipedia.org/wiki/Segmentation_(biology) segmentation], meaning that their body develops in uniform portions.

Archaic segmentverma had a long nerve cord running down the length of their body, which coalesced into a ganglion near the fore end. Simple eyes ran along the underside of segmentverma, allowing them to see small prey and detritus on the seabed.

Segmentverma have a gonadal segment on their penultimate segment, and reproduce through [//en.wikipedia.org/wiki/Spawn_(biology) spawning]. Larval segmentverma look much like smaller versions of the adults, going through no major body changes as they grow.
