A recent study describes how researchers closely observed humpback whales in Southeast Alaska using advanced technology including drones and special tags that monitor their movements and behaviours. What they’ve discovered is fascinating: humpback whales create intricate bubble-nets by releasing air from their blowholes while swimming in circles. These bubbles rise to the surface, forming a net-like structure that traps krill and small fish.

A review published in the journal Animal Sentience describes the surprising abilities found so far among octopus species.

HMS Hawke was discovered earlier this week after an extensive search by Lost in Waters Deep—a group that searches for WWI shipwrecks—about 70 miles off the Aberdeenshire coast. It was found to be in "remarkable" condition, lying at a depth of around 110 metres (360ft).
