Archipelagos’ research boat Naftilos has departed this morning for an important research which takes place in the framework of the ACCOBAMS Survey Initiative: the first large-scale parallel census of cetacean populations throughout the Mediterranean Sea. This challenging research mission of Naftilos will last 2 months and will cover the marine region between Crete, Libya, Tunisia and Malta. One of the target species of this survey is the Sperm whale (Physeter macrocephalus) – the increadible deep diver of our seas. It is surprising how little we know about the status of the Mediterranean subpopulation of this species. The presence of these fascinating animals is described in the Greek Seas since the antiquity, with the impressive for the time, recordings of the philosopher Aristotle. When we are unaware of the important wildlife of our seas, it is impossible to protect it!
