Burrows and burrowing behaviour of fish
1992Abstract The burrowing strategies of fish are reviewed. Excavatory techniques consist of excavation by mouth and displacement of sediment by body movements. The resulting burrows are structurally diverse, but may be divided into those in which the main development is horizontal and those in which it is vertical.

Journal of Morphology, 1976
AbstractMore than 95% of burrowing Anura dig hindfeet first into the soil, a pattern unique to frogs among terrestrial vertebrates. The postero‐laterally placed hindlimbs and associated musculature of frogs are preadaptations for hindfeet digging. One fossorial, backwards burrower, Glyphoglossus molossus (Microhylidae), has morphological modifications ...

Burrows and Burrowing Behavior of Onychomys leucogaster
Journal of Mammalogy, 1965A study of the shelter-seeking behavior of captive northern grasshopper mice was made in 15 × 15 × 3 ft sheet metal enclosures. Observations showed that grasshopper mice invariably dug their own burrows. The following types of burrows were recognized: nest burrows, retreat burrows, cache burrows and miscellaneous burrows, including those used for ...

Burrowing mechanics: burrow extension by crack propagation.
Nature, 2005Until now, the analysis of burrowing mechanics has neglected the mechanical properties of impeding, muddy, cohesive sediments, which behave like elastic solids. Here we show that burrowers can progress through such sediments by using a mechanically efficient, previously unsuspected mechanism--crack propagation--in which an alternating 'anchor' system ...

Burrows and burrowing animals: an overview
1992Abstract A wide range of animals, including man, are known to burrow in terrestrial and aquatic environments, and burrows have been recorded well back in the fossil record. Burrow size and shape is a characteristic of each species. The size of burrows can range from a few millimetres to many metres in length. Burrows may be either simple

Burrowing Hair (Pili Cuniculati)
Archives of Dermatology, 1962Two cases of penetration of human hair under the skin have been reported in the literature. 1,2 The clinical appearance has been compared to cases of larva migrans. The hair is described as embedded in the skin. According to the dictionary, embedding is a histologic laboratory procedure, nothing more.
