ghting report.] [Footnote 16: Describe any tags seen (see Appendix A) and state their size, shape, color, and position on the animal's body and any symbols or numbers they contain.] APPENDIX C STRANDED WHALES, DOLPHINS, AND PORPOISES With a Key to the Identification of Stranded Cetaceans of the Western North Atlantic Stranded Animals As we discussed briefly in the introduction to this guide, whales, dolphins, and porpoises sometimes "strand" or "beach" themselves, individually or in entire herds, for a complex of still incompletely understood reasons. Though the reasons suggested for these strandings appear almost as numerous as the strandings themselves, two tenable generalizations have recently been proposed. Strandings of lone individuals usually involve an animal which is sick or injured. Mass strandings, involving from several to several hundred individuals, appear to be far more complex and may result from fear reactions, from extremely bad weather conditions, from herd-wide disease conditions, or from failure of the echolocation system due to physiological problems or environmental conditions which combine to reduce its effectiveness, to mention only a few. Whatever their causes, however, cetacean strandings usually attract crowds and elicit much public interest and sympathy. There are frequently attempts to save the lives of the animals involved. Individually stranded cetaceans rarely survive, even if they are found soon after stranding and transported to adequate holding facilities. This does not mean that every attempt should not be made to save them. In mass strandings, some individuals may be entirely healthy, and if they are found soon enough after stranding, properly protected and transported, and correctly cared for in the initial few days after collection, they may survive in captivity. Attempts to rescue all the animals in a mass stranding by towing them out to sea have almost always been frustrating because the animals usually swim repeatedly back onto the beach. If you discover a stranding and before you become involved in an attempt to save a live stranded animal or to collect data from a dead one, you should be aware of the following: MARINE MAMMALS ARE CURRENTLY PROTECTED BY LAW. Under provisions of the Marine Mammal Protection Act of 1972, it is unlawful for persons without a permit to handle, harass, or possess any marine mammal. It is within the authority of S
