Release of a nurse shark

In August 2009, the Aquarium des Lagons released a nurse shark weighing over 250 kg. She (it was a female, fondly nicknamed Mammy by the staff) was getting to be too big for her tank. In order to transfer her to her natural element, she had to be anaesthetised and lifted by helicopter! Since that, she has been occasionally spotted near a small islet in the southern lagoon reserve..
