Origin of 'poriferan'

The term 'poriferan' is derived from the Latin words 'pore' and 'ferre', which mean 'pore-bearing'. The classification of poriferans as a distinct group dates back to the 19th century, when scientists recognized sponges as a unique lineage within the animal kingdom. Poriferans are considered one of the most primitive animal groups, with a fossil record dating back over 600 million years.
