wander by mistake.




-Salps are very strange creatures. They are organized in colonies to travel through the oceans. They are plankonic organisms so a current may drift the whole colony near to the coast. This will doom the colony to death.
-This specie is also called giant salp. I don't know if the ring colony of the first photo take that shape because it is too close to the shore.
-It was too late for the individual to get off the colonie. After some minutes it gonna crash on the rocks. (second photo)

Atlantic trumpet triton - Βούκινο ή Μπουρού



One animal that it is referred to the Mediterranean culture is Atlantic trumpet Triton or Charonia variegata. This specie used to be called Charonia tritonis variegata and that's the reason of confusion with his Indo-Pacific cousin Charonia tritonis (which used to be called Charonia tritonis tritonis). In Mediterranean Sea we can meet one more member of the family the Charonia lampas which can grow bigger than C.variegata but it is relatively rare to meet it at the eastern part of Mediterranean sea.
Tritons take their name by an ancient god of Greeks who was the messenger of the sea and son of Poseidon. They also called trumpet because of their shape and of the fact that their shell was used by the ancient civilization as a trumpet. The bad habit of the divers collecting the Tritons for their shells is a danger for their population. If we like their shell we have to wait until we found an empty one at the beach. Also we should avoid buying this shells at markets. It is said that it lives more than 20 years.
It feeds mainly on seastars and other molluscs. It is makes big distances to find a seastar and it likes moving straight-line undisturbed by any blocks. They have separated sexes.

European barracuda - Λούτσος

- minimum population doubling time more than 14 years http://fishbase.org/summary/Speciessummary.php?id=1765
- when travelling they form school of hundred fish that move peacefully. They look like a river in the sea (if you witness it u/w).
- small school may hunt in an area for several days (ex. a reef or a rock area at sandy bottom). The school makes periodiacal appearances in the area. I think that barracuda strategy is to leave the area so that the other fishes get-off the alert and then suddenly come back with more chances of successful hunting.
-Staying calm u/w will allow you come go near the fishes. Easier is to stay moveless and let the fishes aproach you.
