Specimen above found on the non-native bryozoan Bugula neritina on a pontoon at Newlyn Marina, Newlyn, Cornwall, 04.09.20.

The structures seen in the microscope images above are not true conules. Conules are typical of the genus Sycon. The structures above are conule-like and structures like this are more typical in the genus Grantessa for example. Michelle Klautau.

This may be the young form of the species listed here as "Pendant calcareous sponge (unidentified, not Sycon), Newlyn Marina, Cornwall, over 300mm+ in length", but it could also be something entirely different, only time will tell.

APHOTOMARINE supports open source data recording and sharing for the benefit of wildlife, recorders, research, science and education. The project recommends the following websites and works with the following bodies and organisations.

Sponges of Britain and Ireland Picton

A website based on Sponges of the British Isles 1992 Edition, revised and extended, 2007, by Bernard Picton, Christine Morrow & Rob van Soest. Without a shadow of a doubt the best online resource to sponges of Britain and Ireland.

Marine Biological Association MBA

The Marine Biological Association or MBA, based in Plymouth, is one of the world’s longest-running societies dedicated to promoting research into our oceans and the life they support. Since 1884 the MBA has been providing a unified, clear, independent voice on behalf of the marine biological community.It has a growing membership in over 40 countries.

NBN National Biodiversity Network

The National Biodiversity Network or NBN is a charity that supports open source data sharing and recording supporting conservation, science and education. "Why do recorders need open source?". Simply because it supports the core values of wildlife recording and the free use of records and data over a very wide network that includes partners like the Natural History Museum.

The taxonomy used here is based on that of the following database, which is also used by the MBA, NHM and the NBN.

World Register of Marine Species or WoRMS

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help
people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
