On Friday 25 November, diver Arthur Castillo, 60, was found guilty of the involuntary homicide of his long-time dive buddy Christine Gauci who died following a dive in Mgarr ix-Xini, a bay on the southern coast of Gozo in January 2020. Ms Gauci was an Armed Forces of Malta member, diving instructor and technical diver.

The court handed Mr. Castillo a two-year jail term suspended for four years, pronouncing itself convinced that this case did not merit effective imprisonment. Castillo told Times of Malta he will be appealing the judgment but declined further comment.

After studying more than 23,000 sperm whale vocalisations recorded from 1978 to 2017 in the Pacific Ocean, researchers have concluded that sperm whales use distinctive vocalisations to identify themselves with specific whale clans.

Called “identity codas,” these vocalisations comprise sequences of clicking sounds that distinguish different social groups. They are different from non-identity vocalisations used across all the different whale clans.
