The family of sea cucumbers that includes the genus Cucumaria, marine animals belonging to the phylum Echinodermata.
From Cucumaria (genus name) plus the standard taxonomic suffix -idae used for animal families in binomial nomenclature.
When scientists formally name a whole family, they honor the first major genus discovered in it—so an entire family of thousands of sea creatures carries the Latin name for 'little cucumber.'
