Immobilization of Elephant Seals using Succinylcholine Chloride

Abstract

BIOLOGISTS of the Australian National Antarctic Research Expeditions have been investigating the ecology and physiology of the southern elephant seal, Mirounga leonina Linn, at Macquarie Island for many years1. Present work requires the animals to be handled for a variety of procedures, but their large size (mature cows 2½ m long and 500 kg in weight; mature bulls 5 m long and 3,000 kg in weight) makes physical restraint of any but small pups impossible.
