British Divers Marine Life Rescue

It uses a network of trained volunteers around the country to respond to marine mammals potentially in need of assistance via a public 24hr hotline and callout system.

The organisation's main areas of operation are in the United Kingdom and its territorial waters; however, the charity has received requests from Canada, the Falkland Islands, Kenya, Ireland, Italy, Kazakhstan, Malta and Abu Dhabi.

The organization received media attention in January 2006 due to its response to Willy, a northern bottlenose whale that became disorientated and later stranded after swimming up the River Thames into central London.

A large operation began on the morning of Saturday 21 January and lasted until the evening when the whale died prior to being put to sleep by a specialist marine mammal veterinarian due to its poor health.

In 2018, the BDMLR also took part in monitoring Benny, a beluga whale who had been sighted foraging in the Thames Estuary, and in 2021 managed Wally the walrus during his time at the Isles of Scilly where he unintentionally damaged unmanned dinghies by attempting to haul out on them.

Eventually, the team managed to attach the rig within a meter of the whale's tail, and the buoy was quickly pulled into position using a pulley arrangement they had constructed.
