'''''Iophon''''' is a genus of sponges belonging to the family Acarnidae.<ref name="GBIF">{{cite web |title=Iophon Gray, 1867 |url=https://www.gbif.org/species/2242453 |website=www.gbif.org |access-date=6 May 2021 |language=en}}</ref> The genus has a cosmopolitan distribution.<ref name="GBIF" />
== Description == This genus contains species with non-fistulose, massive, branching or encrusting growth forms. The ectosomal (outer) skeleton is made of tylotes (long, slender megascleres with knobs at both ends) with microspined bases.<ref name=":0">{{Citation|last=Hooper|first=John N.

Bipocilla are unique to this genus. They are modified anisochela in which the wing-like alae are joined together by a short curved shaft.<ref>{{Cite web|title=Marine Species Identification Portal : Sponges of the NE Atlantic : Glossary : bipocillum|url=http://species-identification.org/species.php?species_group=sponges&selected=definitie&menuentry=woordenlijst&record=bipocillum|access-date=2021-08-15|website=species-identification.org}}</ref> Toxas are absent.<ref name=":0" />
