Dwarfism is a condition of people and animals marked by unusually small size or short stature. [1] In humans, it is sometimes defined as an adult height of less than 147 centimetres (4 ft 10 in), regardless of sex; the average adult height among people with dwarfism is 120 centimetres (4 ft). [2][3][4] Disproportionate dwarfism is characterized ...
Achondroplasia is a genetic disorder with an autosomal dominant pattern of inheritance whose primary feature is dwarfism. [3] It is the most common cause of dwarfism [4] and affects about 1 in 27,500 people. [3] In those with the condition, the arms and legs are short, while the torso is typically of normal length. [3]
[4] [5] The smallest owl—weighing as little as 31 g ( 1 + 3 ⁄ 32 oz) and measuring some 13.5 cm ( 5 + 1 ⁄ 4 in)—is the elf owl ( Micrathene whitneyi ). [ 6 ] Around the same diminutive length, although slightly heavier, are the lesser known long-whiskered owlet ( Xenoglaux loweryi ) and Tamaulipas pygmy owl ( Glaucidium sanchezi ). [ 6 ]

The orangutans are the only surviving species of the subfamily Ponginae, which diverged genetically from the other hominids (gorillas, chimpanzees, and humans) between 19.3 and 15.7 million years ago. The most arboreal of the great apes, orangutans spend most of their time in trees.
Excess or reduced body weight is regarded as an indicator of determining a person's health, with body volume measurement providing an extra dimension by calculating the distribution of body weight. Average adult human weight varies by continent, from about 60 kg (130 lb) in Asia and Africa to about 80 kg (180 lb) in North America, with men on ...
The tail measures 29–50 cm (11–20 in) in length, the ears 90–110 mm (3 + 1 ⁄ 2 – 4 + 3 ⁄ 8 in) in height, and the hind feet are 220–250 mm (8 + 5 ⁄ 8 – 9 + 7 ⁄ 8 in). [42] The size and weight of the modern wolf increases proportionally with latitude in accordance with Bergmann's rule . [ 43 ]
