Myth or truth: investigation of the jumping ability of Tunga penetrans (Siphonaptera: Tungidae).. Female sand fleas (Tunga penetrans Linnaeus, 1758, Siphonaptera: Tungidae) cause a severe parasitic skin disease known as tungiasis. T. penetrans is a small flea, measuring less than 1 mm in length. The females of this species burrow into the skin of human and animal hosts and mostly affect the feet. This has led to the anecdotal assumption that T. penetrans, unlike its relatives in the Siphonaptera family, would have a limited jumping ability potentially not reaching higher body parts. However, there is no data supporting this. This study evaluated the jumping capabilities of T. penetrans for…

Insect-scale jumping robots enabled by a dynamic buckling cascade. Millions of years of evolution have allowed animals to develop unusual locomotion capabilities. A striking example is the legless-jumping of click beetles and trap-jaw ants, which jump more than 10 times their body length. Their delicate musculoskeletal system amplifies their muscles' power. It is challenging to engineer insect-scale jumpers that use onboard actuators for both elastic energy storage and power amplification. Typical jumpers require a combination of at least two actuator mechanisms for elastic energy storage and jump triggering, leading to complex designs having many parts. Here, we report the new concept of d…

Impact of hindlimb length variation on jumping dynamics in the Longshanks mouse. Distantly related mammals (e.g. jerboa, tarsiers, kangaroos) have convergently evolved elongated hindlimbs relative to body size. Limb elongation is hypothesized to make these species more effective jumpers by increasing their kinetic energy output (through greater forces or acceleration distances), thereby increasing take-off velocity and jump distance. This hypothesis, however, has rarely been tested at the population level, where natural selection operates. We examined the relationship between limb length, muscular traits and dynamics using Longshanks mice, which were selectively bred over 22 generations for…

The Manx cat (, in earlier times often spelled Manks) is a breed of domestic cat (Felis catus) originating on the Isle of Man, with a mutation that shortens the tail. Many Manx have a small stub of a tail, but Manx cats are best known as being entirely tailless; this is the most distinguishing characteristic of the breed, along with elongated hind legs and a rounded head. Manx cats come in all coat colours and patterns, though all-white specimens are rare, and the coat range of the original stock was more limited. Long-haired variants are sometimes considered a separate breed, the Cymric cat. Manx are prized as skilled hunters, and thus have often been sought by farmers with rodent problems…

The clouded leopard (Neofelis nebulosa), also called mainland clouded leopard, is a wild cat that has large dusky-grey blotches and irregular spots and stripes reminiscent of clouds. Its head-and-body length ranges from 68.6 to 108 cm (27.0 to 42.5 in) with a 61 to 91 cm (24 to 36 in) long tail, which it uses for balancing when moving in trees. The clouded leopard was first described in 1821 on the basis of a skin of an individual from China. It is the sister taxon to other pantherine cats, having genetically diverged 9.32 to 4.47 million years ago. It inhabits dense forests from the foothills of the Himalayas through Northeast India and Bhutan to mainland Southeast Asia into South China. I…

Biomechanical modeling of Border Collies ( Canis familiaris ) for insights of tail and limb use during the aerial phase of jumping. Abstract Dogs and other members of Canidae utilize their tails for different purposes, including agile movements, such as running and jumping. In this study, we utilized motion capture biomechanical data of a border collie executing an agile rotational jump maneuver. This data created a 17-segment biomechanical model of the border collie’s ( Canis familiaris) limb movement during agile jumps. This model was verified by comparing it to the biomechanical movement and fitting the dog’s agile task with an RMSE less than 2.5%. Using this joint model, we held specifi…

The Siberian is a centuries-old landrace (natural variety) of domestic cat in Russia, and recently developed as a formal breed with standards promulgated the world over since the late-1980s. Since 2006, the breed is recognised for registry and championship status with all major cat registries. The formal name of the breed is Siberian Forest Cat, but it is typically referred to as the Siberian or Siberian cat. Formerly, sometimes the names Moscow Semi-Longhair and Russian Longhair were also used. The colourpoint variant or sister breed, called the Neva Masquerade, is categorised as a separate cat breed by some registries, including FIFe, WCF, and ACF. The breed developed from an ancient, nat…
