North Cyprus is an ideal location for snorkelling and scuba diving, with its largely unspoilt coastline and year-round warm waters that rarely drop below 17 degrees centigrade. There are also no tides to worry about and you can enjoy one of the longest diving seasons in the world, which lasts from April through to the New Year. The island’s fascinating history spanning several empires also means there is much to explore underwater, including many exciting shipwrecks.

A study published in Nature demonstrates that fish have a natural rhythm that could help them avoid being eaten by predators

A team from the University of California led by Dr Mu-Ming Poo made the discovery during experiments with zebrafish, a type of minnow. They discovered that the larvae of the fish, which were trained to flip their tails every time a light flashed at six-second intervals, "remembered" the rhythm even after the flash was turned off.

The reason why the fish kept time was a mystery but it could be to help it keep track of time and defend itself.

"Our study represents important progress towards understanding the evolution and biodiversity of corals and provides a foundation for future work. Since coral ecosystems are increasingly threatened, there is a need to characterize and understand coral species in terms of interbreeding groups as opposed to nominal morphological units", said Zac Forsman, who led a team of researchers from the Hawai'i Institute of Marine Biology carrying out the molecular studies.

The aim of this thesis was to study the chemical communication involved in aggressive and reproductive behaviours in the European lobster (Homarus gammarus). Both male and female H. gammarus established and maintained dominance, but the sexes used different strategies for dominance maintenance.

Male losers recognised individual fight opponents and avoided them but fought actively against unfamiliar dominants. In contrast, female losers avoided both familiar and unfamiliar dominants, indicating that they react to the dominance status of the opponent.
