The INDEPENDENT reports more jet-skiers, kayakers, boat-trippers and drones are alarming dolphins and seals. Wildlife experts have celebrated “extraordinary” sightings of Scottish bottlenose dolphins off the Yorkshire coast – thought to be the farthest south that they have ever been spotted on the UK’s east coast. They have also discovered a seal “commuting” between the Isle of Man and Cornwall to have pups and search for food. But the discoveries – among the success stories for UK marine life in 2019 – were marred by finding that a greater number of jet skiers, kayakers and boat-trippers, as well as drones, were causing the marine mammals to panic.
