We are very grateful to D. Browne (Bord Iascaigh Mhara), M. Hawkins (Galway Atlantaquaria) and K. Flannery (Dingle Oceanworld), for providing study material. We would also like to thank G. Flemming (National University of Ireland, Galway) for providing valuable advice on culturing marine bacteria, T. Muldoon (University College Hospital Galway) for running the mucicarmine stain, P. White (Galway-Mayo Institute of Technology) and O. Thomas (National University of Ireland, Galway) for their help with GC-MS and LC-MS respectively.

N2 - Embryos of oviparous chondrichthyans develop within a structurally complex tertiary egg envelope known as the egg-case, which is provisioned with a secondary egg coat known as the egg-jelly. Whereas the former has been studied in detail, relatively little attention has been paid to the latter. This study examined the production and composition of egg-jelly in the small-spotted catshark Scyliorhinus canicula (Linnaeus, 1758) and determined that it is a mucin hydrogel. The role of the egg-jelly appears to be one of simple, physical support for the developing embryo, as it was not found to possess bactericidal properties, nor did its constituents suggest a nutritive role.
