False Killer Whale - Pseudorca crassidens
The False killer whale (Pseudorca crassidens) is a cetacean, and the third largest member of the oceanic dolphin family (Delphinidae). It lives in temperate and tropical waters throughout the world. As its name implies, the False killer whale shares characteristics, such as appearance, with the more widely known Orca (killer whale). Like the orca, the False killer whale attacks and kills other cetaceans. However, the two dolphin species are not closely related. The False killer whale appears to have a widespread, if small, presence in temperate and tropical oceanic waters. They have been sighted in fairly shallow waters such as the Mediterranean Sea and Red Sea as well as the Atlantic Ocean (from Scotland to Argentina), the Indian Ocean (in coastal regions and around the Lakshwadweep islands) and the Pacific Ocean (from the Sea of Japan to New Zealand and the tropical area of the eastern side), and also in Hawaii. The eastern tropical Pacific is estimated to have in excess of 40,000 individuals and is probably the largest population. The False killer whale is black with a grey throat and neck. It has a slender body with an elongated tapered head and 44 teeth. The dorsal fin is sickle-shaped and its flippers are narrow, short and pointed. The average size is around 4.9 m (16 ft). Females can reach a maximum known size 5.1 m (17 ft) in length and weigh 1,200 kg (2,600 lb), while the largest males can reach 6.1 m (20 ft) and weigh as much as 2,200 kg (4,900 lb).

Hippopotamus - Hippopotamus amphibius
The hippopotamus (Hippopotamus amphibius), or hippo, from the ancient Greek for "river horse" (ἱπποπόταμος), is a large, mostly herbivorous mammal in sub-Saharan Africa, and one of only two extant species in the family Hippopotamidae (the other is the Pygmy Hippopotamus.) After the elephant and rhinoceros, the hippopotamus is the third largest land mammal and the heaviest extant artiodactyl. The hippopotamus is semi-aquatic, inhabiting rivers, lakes and mangrove swamps where territorial bulls preside over a stretch of river and groups of 5 to 30 females and young. During the day they remain cool by staying in the water or mud; reproduction and childbirth both occur in water. They emerge at dusk to graze on grass. While hippopotamuses rest near each other in the water, grazing is a solitary activity and hippos are not territorial on land. The hippopotamus is recognizable by its barrel-shaped torso, enormous mouth and teeth, nearly hairless body, stubby legs and tremendous size. It is the third largest land mammal by weight (between 1½ and 3 tonnes), behind the white rhinoceros (1½ to 3½ tonnes) and the three species of elephant (3 to 9 tonnes). The hippopotamus is one of the largest quadrupeds (four legged mammals). Despite its stocky shape and short legs, it can easily outrun a human. Hippos have been clocked at 30 km/h (19 mph) over short distances. The hippopotamus is one of the most aggressive creatures in the world and is often regarded as one of the most dangerous animals in Africa. There are an estimated 125,000 to 150,000 hippos throughout Sub-Saharan Africa; Zambia (40,000) and Tanzania (20,000–30,000) possess the largest populations. They are still threatened by habitat loss and poaching for their meat and ivory canine teeth. Hippopotamuses are among the largest living mammals; only elephants and some rhinoceroses and whales are heavier. They can live in the water or on land. Their specific gravity allows them to sink and walk or run along the bottom of a river. Hippos are considered megafauna, but unlike all other African megafauna, hippos have adapted for a semi-aquatic life in freshwater lakes and rivers. Because of their enormous size, hippopotamuses are difficult to weigh in the wild. Most estimates of the weight come from culling operations that were carried out in the 1960s. The average weight for adult males is 1,500 kg (3,300 lb). Females are smaller than their male counterparts, with average weights measuring between 1,300–1,500 kg (2,900–3,300 lb). Older males can get much larger, reaching at least 3,200 kg (7,100 lb) and occasionally weighing 4,500 kg (9,900 lb). Male hippos appear to continue growing throughout their lives; females reach a maximum weight at around age 25.
