Window at the bottom: The beautiful Spirograph Marine Worm

Window at the bottom – Marine organisms of Kefalonia & Ithaca

 The beautiful Spirograph

Spirograph is a marine worm with an elongated body, from which two or more (depending on the species) series of tentacles are in the form of wings and impressive colors. These attachments create clusters or spirals that take up oxygen and release carbon dioxide (a product of metabolism, as we do – we even share with these creatures) and filter the water that is moving in the sea currents by collecting plankton, but they also give Spirograph his name!

A lover of riot and dance  

It is usually found in rocky seabed in shallow waters but also in depths up to 50 meters. However, Spirograf is happier near the coast, reef ridges or wreck tips, where the flow becomes stronger, as water is stirred and more plankton is transferred. As if this did not work, he moves his tentacles to help the situation, and this makes him look like a small dancer.

A place on the bottom and a house, forever   

When he is still a larva and travels with the bottom currents, he ends up at a point where he will make his home. He will remain there forever: by collecting particles of sand and mud and using mucus to excrete, he makes a smooth tube about 25 centimeters long, in which he lives. This tube is at one end anchored to the rocky bed substrate or to rock outcrops, while the other end is rocked at the flow rate. When things are quiet, Spirograf dries out and extends his “wings”, so the meal begins! If you feel threatened or annoyed, it rises again in the tube, so the meal is over. So next time you see a Spirograph in the sea and before you go too far, think about whether you would like to stop your own meal.

Our seas

Pictures come from diving in the waters of the Ionian Sea and more specifically of Kefalonia and Ithaca. They depict species that inhabit and enrich our own seas, those that are next to us, and hosts the inhabitants and visitors of our islands in the winter or summer.

The hidden wealth of the sea is no different from its biodiversity. And it is hidden not because it has not been discovered but because it remains unknown to most, so that in general it is considered a vast area empty of any interest, as well as the place of rejection of our waste.

The sea is a cradle for life, a food for man and a lung for the planet.

But to protect it we must first meet it!
