Each entry also provides the common name of the animal. If the relevant taxon includes different animals with different common names, then the entry provides the common name of a familiar example. If juveniles have fewer legs than adults, then the animal is listed by the number of legs recorded in mature adults.
These animals have evolved to only need one pair of limbs, whether arms or legs. Any other limbs have not only become vestigial but have disappeared altogether.
Panarthropoda: no less than four legs. Velvet worms and some arthropods have more than a dozen legs; a few species possess over one hundred. Despite what their names might suggest, centipedes ("hundred feet") may have fewer than twenty or more than 300 legs, and millipedes ("thousand feet") have fewer than 1,000 legs, but up to 750.
Study co-author Andrew Marshall described the new species as “alien-faced” with “about 200 legs,” according to a Feb. 1 news release from the University of the Sunshine Coast in Australia.
Many vertebrates are limbless, limb-reduced, or apodous, with a body plan consisting of a head and vertebral column, but no adjoining limbs such as legs or fins. Jawless fish are limbless but may have preceded the evolution of vertebrate limbs, whereas numerous reptile and amphibian lineages – and some eels and eel-like fish – independently lost their limbs.
The ventral sides of the ultimate legs feature dense short setae in males and often some short setae in females, but these legs lack an apical spine. [3] [17] This species exhibits many traits shared with other Mecistocephalus species. For example, like other centipedes in the same genus, this species features an elongated head with spicula and ...
Females can have from 73 to 85 pairs of legs, whereas males can have from 67 to 77 pairs, most often 73 pairs. [4] A specimen from Madagascar with even fewer legs (53 pairs, sex not reported) [5] features the minimum number recorded in the family Orydae. [6]
Diagram of a spider leg and pedipalp – the pedipalp has one fewer segment. Arachnid legs differ from those of insects by the addition of two segments on either side of the tibia, the patella between the femur and the tibia, and the metatarsus (sometimes called basitarsus) between the tibia and the tarsus (sometimes called telotarsus), making a total of seven segments.
