Tarsiers are small animals with enormous eyes; each eyeball is approximately 16 millimetres (0.63 in) in diameter and is as large as, or in some cases larger than, its entire brain. [ 16 ] [ 17 ] The unique cranial anatomy of the tarsier results from the need to balance their large eyes and heavy head so they are able to wait silently for ...
Macrotis means 'big-eared' (macro-+ ōt-'ear') in Greek, referring to the animal's large, long ears. [4] The genus name was first proposed as a subgeneric classification, which after a century of taxonomic confusion was eventually stabilised as the accepted name in a 1932 revision by Ellis Troughton. In reviewing the systematic arrangement of ...
It has a long neck, and large, flexible ears. Its coat is a chocolate to reddish brown, much in contrast with the white horizontal stripes and rings on the legs, and white ankles. Male okapis have short, distinct horn-like protuberances on their heads called ossicones , less than 15 cm (5.9 in) in length.
Most are fast runners with long, powerful hind legs, and large ears that dissipate body heat. [1] Hare species are native to Africa, Eurasia and North America. A hare less than one year old is called a "leveret". A group of hares is called a "husk", a "down", or a "drove".
Researchers have found that, when jerboas execute their vertical leaps, the primary tendons in the hindlimbs only recovered and reused on average 4.4% of energy contributed to the jump; this is lower than many hopping animals. [4] Jerboas have metatarsal bones that are fused into one long bone, called the cannon bone.
Compared to bandicoots, they have a longer tail, bigger ears, and softer, silky fur. The size of their ears allows them to have better hearing as well. At 1 to 2.4 kilograms (2.2 to 5.3 lb), the male is about the same size as a rabbit; although male animals in good condition have been known to grow up to 3.7 kilograms (8.2 lb) in captivity. The ...
Giraffidae: Giraffids have a pair of skin covered bony bumps on their heads, called ossicones. Cervidae: Most deer have antlers, which are not true horns due to lacking a bone core and made of keratin. Rhinocerotidae: The "horns" of rhinos are made of keratin and lack a bone core.
Studies have shown that an individual barn owl may eat one or more voles (or their equivalent) per night, equivalent to about fourteen percent of the bird's bodyweight. Excess food is often cached at roosting sites and can be used when food is scarce. [40] This makes the barn owl one of the most economically valuable wildlife animals for ...
