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 ...
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.
Centipedes have one pair of legs per body segment, with typically around 50 legs, but some species have over 200. The terrestrial animals with the most legs are the millipedes. They have two pairs of legs per body segment, with common species having between 80 and 400 legs overall – with the rare species Illacme plenipes having up to 750 legs ...
Using their long, powerful back legs, they catapult themselves into the air and land in an upright posture on a nearby tree, with both hands and feet tightly gripping the trunk. [17] Indriids can leap up to 10 m (33 ft) rapidly from tree trunk to tree trunk, [ 17 ] [ 68 ] an ability referred to as "ricochetal leaping". [ 78 ]
With a beaver’s tail, webbed feet, and a duck’s bill, platypuses are one of the world’s strangest-looking creatures. They are such an unusual mammal that the first scientists to study them ...
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 Bluntnose sixgill shark is one of four shark species that have six gill pairs. Other three are - Frilled shark (Chlamydoselachus anguineus), Bigeyed sixgill shark (Hexanchus nakamurai) [4]) and Atlantic sixgill shark (Hexanchus vitulus) The bluntnose sixgill shark has a large body and long tail. The snout is blunt and wide, and its eyes are ...
Their long tails, covered with scales rather than hair, are laterally compressed and generate a small amount of thrust, with their webbed hind feet being the main means of propulsion, [3] and the unique tail mainly important in directional stability. Muskrats spend most of their time in the water and can swim underwater for 12 to 17 minutes.
