Bullmastiff: The bullmastiff is a large breed of domestic dog. It has a solid build and a short muzzle. The bullmastiff shares the characteristics of Molosser dogs, and was originally developed by 19th-century gamekeepers to guard estates. The breed's bloodlines are drawn from the English Mastiff and Old English Bulldog. It was recognized as a purebred dog by the English Kennel Club in 1924. They are a very quiet dog; they very rarely bark. Males should be 25 to 28 inches (64 to 71 cm) tall (AKC Std.) at the withers and 110 to 130 pounds (50 to 59 kg). Females should be 24 to 26 inches (61 to 66 cm) at the withers, and 100 to 120 pounds (45 to 54 kg). Exceeding these dimensions is discouraged by breeders.

Sperm Whale: (Physeter macrocephalus), or cachalot, is the largest of the toothed whales. It is the only living member of genus Physeter, and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia. Mature males average at 16 metres (52 ft) in length but some may reach 20.5 metres (67 ft), with the head representing up to one-third of the animal's length. The sperm whale feeds primarily on giant and colossal squid. Plunging to 3 kilometres (9,800 ft) for prey, it is the deepest diving mammal.
