Echiura facts for kids
Temporal range: Upper Carboniferous – Recent
|Bonellia viridis, female|
The Echiura, or spoon worms, are a small group of marine animals. They are often considered to be a group of annelids, although they lack the segmented structure found in other members of that group, and so may also be treated as a separate phylum.
However, phylogenetic analyses of DNA sequences place echiurans and sipuncula within the Annelida.
