Recently I have found an amazing course which I think will defiantly make any aspiring vets stand out a little more. The course is a Marine Mammal Medic training course with the British Divers Marine Life Rescue.
These are sessions in which you will be shown what to do in situations of animal rescue by the sea, for example strandings of seals, dolphins and whales.
However you do have to pay for these courses and they are only in select places. The course usually costs around £90 and on the British Divers Marine Life Rescue website (http://www.bdmlr.org.uk/) you can find more information about the courses around the UK.
