Saving A Whale, Cetacean Stranding, Popoyo Beach, Tola Municipality, Rivas Department, Nicaragua

Species
Every year up to 2,000 animals beach themselves. Although the majority of strandings result in death, they pose no threat to any species as a whole. Only about 10 cetacean species frequently display mass beachings, with 10 more rarely doing so.
All frequently involved species are toothed whales (Odontocetes), rather than baleen whales. These species share some characteristics which may explain why they beach.
Body size does not normally affect the frequency, but both the animals' normal habitat and social organization do appear to influence their chances of coming ashore in large numbers. Odontocetes that normally inhabit deep waters and live in large, tightly knit groups are the most susceptible. They include the sperm whale, a few species of pilot and killer whales, a few beaked whales and some oceanic dolphins.
