Four classes of arthropods each provide multiple examples, including sea spiders (with 4 to 6 leg pairs, [11] providing two examples) and pauropods (adults with 8 to 11 leg pairs, [12] providing four examples), but most of the examples listed are either millipedes (adults with 11 to 653 leg pairs) [5] [1] or centipedes (adults with 15 to 191 ...
Close-up of a ruffed lemur's foot, showing the toilet-claw on the second toe and nails on all other toes. Like all primates, lemurs have five divergent digits with nails (in most cases) on their hands and feet. Most lemurs possess a laterally compressed, elongated nail, called a toilet-claw, on the second toe and use it for scratching and grooming.
Crepuscular, a classification of animals that are active primarily during twilight, making them similar to nocturnal animals. Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night. Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night.
[62] [63] Cubs born in the wild weigh 150–300 g (5.3–10.6 oz) at birth, while those born in captivity tend to be larger and weigh around 500 g (18 oz). [10] [60] The cheetah is sexually dimorphic, with males larger and heavier than females, but not to the extent seen in other large cats; females have a much lower body mass index than males ...
In Solifugae, the palps are quite leg-like, so that these animals appear to have ten legs. The larvae of mites and Ricinulei have only six legs; a fourth pair usually appears when they moult into nymphs. However, mites are variable: as well as eight, there are adult mites with six or, like in Eriophyoidea, even four legs. [7] [8] While the ...
The subphylum Hexapoda (from Greek for 'six legs') or hexapods comprises the largest clade of arthropods and includes most of the extant arthropod species. It includes the crown group class Insecta (true insects), as well as the much smaller clade Entognatha, which includes three classes of wingless arthropods that were once considered insects: Collembola (springtails), Protura (coneheads) and ...
The buzzard is a known predator of 237 g (8.4 oz) Eurasian sparrowhawks (Accipiter nisus), 184 g (6.5 oz) common kestrel and 152 g (5.4 oz) lesser kestrel (Falco naumanni) . [ 108 ] [ 189 ] Perhaps surprisingly, given the nocturnal habits of this prey, the group of raptorial birds the buzzard is known to hunt most extensively is owls. [ 190 ]
The subfamilies of nightjars have similar characteristics, including small feet, of little use for walking, and long, pointed wings. The common poorwill , Phalaenoptilus nuttallii , is unique as a bird that undergoes a form of hibernation, becoming torpid and with a much reduced body temperature for weeks or months, although other nightjars can ...
