Last summer I joined the British Divers Marine Life Rescue Large Whale Disentanglement Team.  The team are specially trained to remove ropes, nets and other items from around whales and other marine mammals.  This requires a lot of skill and specialist equipment.  The team come from all parts of the country with skills in boat handling and logistics, but are on standby to jump into action.  A successful rescue requires a lot of specialist equipment, such as knives, boats and buoys, which costs money to buy and maintain.  A successful rescue means the life of a rare animal is saved.
