|Other common names||North Atlantic cup sponge||Synonyms||-|
Axinella infundibuliformis is light browny yellow, creamy white or creamy yellow in colour. It is cup shaped or fan -like (lamellate) if the cup is incomplete. The funnel can grow to 10 cm in diameter. The walls have a regular thickness of 3 -4 mm and terminate with rounded and firm edges. The exhalent pores (oscules) are distributed evenly over the inner surface and are larger than the inhalent pores (ostia) on the outer surface.
Recorded distribution in Britain and IrelandFound on the west coasts of Britain and Ireland with records from south west England, Lundy, west Wales, the Isle of Man, south west and northern coasts of Ireland and western coasts of Scotland.
HabitatAxinella infundibuliformis can be found, usually on upward facing rock, from the shallow sublitttoral down to 630 m depths.
- Light browny yellow, creamy white or creamy yellow in colour.
- Cup or cone shaped with the funnel reaching 25 cm in diameter.
- Occasionally fan shaped if cone incompletely formed.
- Body walls of regular thickness (3 -4 mm) with rounded and firm edges.
Phakellia ventilabrum is similar in appearance but has thin walls and tapered, sharp edges to the cup. The composition of the internal skeleton (i.e. the spicules) are important taxonomic characteristics (see van Soest et al., 2000 for details). As with other Axinella species, Axinella infundibuliformis is likely to be extremely slow growing, long lived and does not colonize artificial reefs (K. Hiscock pers. comm.).
