Summer's almost gone but the celebrations continue.



Tomorrow is the beginning of autumn and as every time autumn begins, the summer goes away. As every time the summer goes away, we have to listen to the same song of the Doors .
Ok that’s enough with the matters outside the sea. When the autumn begins, all the virgos of the zodiac cycle celebrate. Unfortunately none of the animals of the eastern Mediterranean is virgin so we don’t have anything to celebrate. No? Of course not! If you look deep in the arthropods' classification, you can find a forgotten family of tremendous crabs called Parthenopidae. Parthenos is the Greek word for the virgin so in honor of this today we will introduce one of the most unknown families of the crabs of Mediterranean Sea. I have met crabs of this family 3 times and I think that all of them belong to the same species but yet I am yet unsure which species it is. I cannot find enough information about this family and this may be, because, these crabs don’t like the lights of publicity.
They prefer spending their time burried in the sand. That’s a pity for the naturalists as they cannot admire their impressive claws and their beautiful purple. The common name for these crabs is elbow crabs to fame their giant chelipeds . Maybe, if you compare them with the body size they are one of the biggest claws in the nature.
According to the Greek mythology, Parthenope was one of the sirens that were trying to seduce Odysseus with her song. Odysseus escapes from the trap and from her despair the siren falls into the sea and dies. The body of the siren washed ashore on a beach in the south of Italia and some travelers from Chalkidians that had just arrived found her. They burried her, and started to make their city around the grave. They gave the city the name Neapolis and this city is the famous untill our days as Naples. Annibale de Gasparis a scientist of astronomy, many centuries later named 11 Parthenope a small planet that he discovered as he was working in Naples.
Summer’s almost gone.

Remember, remember the 6th of December

One of the last pictures I took with my camera (before I violently drowned it, yesterday), was this wicked crab, called Dromia personata that is completely invisible unless it starts eating a jelly fish right in front you!



If you look closely on the middle left of the picture, you will see the side of the sponge crab under its well fitted sponge cover, grabbing the jellyfish by its tentacles and slowly eating it!



So there you see one crab, but the shock was the other one that is hiding behind the jellyfish! And both of them had the jellyfish clawed by both sides! Was it a well thought of attack?Do crabs like to eat jellyfish and work together to capture it?!
Both crabs had a 15cm carapace covered by a well attached sponge, making them COMPLETELY invisible!
These sponge crabs are very curious in that the front of their body is hairy, and the edge of its two front claws is bright pink. Although they may be pink they are huge and should be avoided...poor jellyfish

Crab duo...

Spidercrabs love anemones, and the anemones love the crabs. It seems that neither animals are hurt in this beneficial relationship, the crab is protected by the poisonous tentacles and the anemone is warned for any predators before anyone can suspect otherwise. You see, these crabs cannot be seen easily, you may be taking a picture of one and the other would be giggling behind a tentacle! Amazing camouflage and very hard in identification, unless the carapace is available for closer examination, for example when the crab is shedding. Maybe next time...I know where you live....
Sometimes they like to cover up with sponges, like another resident of Kalogria which will be on the next post.
Until then happy crab hunting!
