Size · not on record: no authority the fetcher reads carries a length for this taxon (a genus page could show the range of its species).
Hydrozoa, also called hydroids, are a taxonomic class of individually very small, predatory animals, some solitary and some colonial, most of which inhabit saline water. The colonies of the colonial species can be large, and in some cases the specialized individual animals cannot survive outside the colony.W CalCOFI holds 1,648 observations of it in 1 dataset between 1951 and 2010, across 2 taxa under it.R

One row per dataset, one cell per year, darker with more observations — the same strip the front
door draws per dataset. Each row ends with the name that dataset uses (dataset_taxon);
the accepted name is written once, in the title above. A quiet pill marks a name the authority does not accept.
