Death of Diane Whipple: Diane Alexis Whipple (January 21, 1968 – January 26, 2001) was a lacrosse player and college coach.  She was killed in a dog attack in San Francisco on January 26, 2001.  The dogs involved were two Presa Canarios: a male named Bane and a female named Hera.  Paul Schneider, the dogs' owner, is a high-ranking member of the Aryan Brotherhood and is serving a life sentence in state prison.  The dogs were cared for by Schneider's husband-and-wife attorneys, Robert Noel and Marjorie Knoller, who lived in the same apartment building as Diane Whipple.  After the fatal attack, the state brought criminal charges against the attorneys.  Robert Noel, who was not present during the attack, was convicted of manslaughter.  Marjorie Knoller, who was present, was charged with implied-malice second-degree murder and convicted by the jury.  Knoller's murder conviction, an unusual result for an unintended dog attack, was rejected by the trial judge but ultimately upheld.  The case clarified the meaning of implied malice murder.

Perro de Presa Canario: The Perro de Presa Canario, A.K.A. the Canary Mastiff, is a large Molosser-type dog breed originally bred for working livestock.  The name of the breed is Spanish, means "Canarian catch dog", and is often shortened to "Presa Canario" or simply "Presa".  The breed is sometimes also called Dogo Canario, meaning "Canarian Molosser".  It is the animal symbol of the island of Gran Canaria.

North American beaver: The North American beaver ("Castor canadensis") is one of two extant beaver species.  It is native to North America and introduced to Patagonia in South America and some European countries (e.g. Finland).  In the United States and Canada, the species is often referred to simply as "beaver", though this causes some confusion because another distantly related rodent, "Aplodontia rufa", is often called the "mountain beaver".  Other vernacular names, including American beaver and Canadian beaver, distinguish this species from the other extant beaver species, "Castor fiber", which is native to Eurasia.  The North American beaver is an official animal symbol of Canada.

Japanese river otter: The Japanese river otter ("Lutra lutra whiteleyi") (日本川獺 , Nihon-kawauso ) is an extinct variety of otter formerly widespread in Japan.  Dating back to the 1880s, it was even seen in Tokyo.  The population suddenly shrank in the 1930s, and the mammal nearly vanished.  Since then, it has only been spotted several times, in 1964 in the Seto Inland Sea, and in the Uwa Sea in 1972 and 1973.  The last official sighting was in the southern part of Kōchi Prefecture in 1979, when it was photographed in the mouth of the Shinjo River in Susaki.  It was subsequently classified as a "Critically Endangered" species on the Japanese Red List.  On August 28, 2012, the Japanese river otter was officially declared extinct by the Ministry of the Environment.  It is the official animal symbol of Ehime Prefecture.  In February 2017, a wild otter was caught on camera on Tsushima Island, Nagasaki Prefecture.  However, it is not known whether the observed otter was a Japanese river otter.
