Double fanworm


Bispira volutacornis is one of the beautiful fanworms of Aegean Sea. Fanworms are worms that prefer living in membranous tubes that creates over steady items even buried in mud or between rocks. The only part of these animals which is visibly is the tube and the double feather-crown that filters water for feeding and breathing. I usually find it on clear shallow waters like solitarily beaches. Its eyes alert the animal if the danger approaches it and rapidly hides its double crown inside the tube. When it is hidden the entrance of the tube closes and makes a peculiar 8. Its crown colour variation is from white (and pinkie white) to brown or reddish brown and depends on the sex and the sexually mature of the animal. B.volutacornis usually prefers solitarily living but sometimes you can meet a couple of them (photo) or more.

Coral worm castle




This little perch has a very impressive castle, made of a rich yellow sponge Aplysina aerophoba and a very fragile colony of coral worms Salmacina dysteri. The coral worms are only tiny but the colonies can reach up to 15 cm in sheltered areas, without nets or clumsy fin strokes.
Don't disturb the dreams and the castles, glide smoothly!
The photos where taken in Pilion, 5m.

A lower-higher level of the food chain!!!




The fire worm is really a charismatic marine species! People may admire a lot of animals like the powerful sharks and marlins and condemn other animals like the worms because they seem to be so weak. Fire worms are not weak; one of the first things that I learnt when I started fishing with hooks at my childhood is not to leave the bait move for a long time. If you do so, fireworks will get it and you don't want to have any contact with those worms. I was lucky enough and this animal never harmed me (this is really strange!!!) but as it is known it has thousands of hard bristles that if they touch your skin you will feel a burning sensation for many days. That's why no marine animals ever eat a fire worm. On the other hand fire worms eat almost everything, even sea anemones. They are also the most successful scavengers in a lot of areas. For scavenging it is believed that they use the organ they have on their head. It is believed that it's something that helps for good smell. (the one that looks like a brain at the first photo). You can find hundreds of them over a dead fish body, just ten minutes after you throw it in the sea. At the second photo you can see a lesson in knots!!!!
