Hi, sorry for posting something that's definetly not an arthropod, but I couldn't find any info about these things, not a clue even... The first thing is an about 30 cm diameter ?colony? of something... Not sponge, I think. I tought about calcarean algae, but they shouldn't be this huge. Any suggestions, please? Was found in Greece this summer, Paralia Katerini. Edited by pwalter on 13-11-2008 11:52 |

Thank You, but I don't know what you mean by sponge fungus... There's one living in forests, I think you ment some kind of slime mould? I think it's too big for that and the species that live in seawater are mainly parasites of algae, the Labirinthulomycota and Hyphochytridiomycota. Best regards, Walter PS: here's a closer view: Edited by pwalter on 20-11-2008 19:01 |

And another thing from the sea (Greece), it was anchored to a rope. First I tought on Tunicate, but couldn't find any species on the net and in books that is black and lives there. |

I think those little pink dots in the second picture look rather like eyes - I think this is an egg mass of some sort - fish or molluscs? The black thing looks a bit like a young seaweed - some sort of brown alga. Tony ---------- Tony Irwin |

Thank You Tony, brown alga seems to be a good idea for me, I'll try to look after the possible species. For the 'egg-mass': I'll give them a closer look, I have parts stored in alcohol. The whole thing was a single mass, but could be torn apart like you can do with a sponge. And it weighed more than 1 kg. So I don't think that any molluscs live there that can produce so much eggs. For fishes, it might be... Thank You very much for your help with these things  |
