Burrowing in the context of "Protection"

Pocket gophers, commonly referred to simply as gophers, are burrowing rodents of the family Geomyidae. The roughly 41 species are all endemic to North and Central America. They are commonly known for their extensive tunneling activities and their ability to damage farms and gardens.

The name "pocket gopher" on its own may refer to any of a number of genera within the family Geomyidae. These are the "true" gophers, but several ground squirrels in the distantly related family Sciuridae are often called "gophers", as well. The origin of the word "gopher" is uncertain; the French gaufre, meaning "waffle", has been suggested, on account of the gopher tunnels resembling the honeycomb-like pattern of holes in a waffle. Some sources suggest a Muskogean origin of the name.

Eriocheir sinensis, the Chinese mitten crab (simplified Chinese: 大闸蟹; traditional Chinese: 大閘蟹; pinyin: dàzháxiè; Jyutping: daai6 zaap6 haai5; Shanghainese: du-zaq-ha, lit. "big sluice crab"; Korean: 참게) or Shanghai hairy crab (上海毛蟹, p Shànghǎi máoxiè), is a medium-sized burrowing crab that is named for its furry claws, which resemble mittens. It is native to rivers, estuaries, and other coastal habitats of East Asia; from Korea in the north to Fujian in the south. It has also been introduced to Europe and North America, where it is considered an invasive species. The species features on the list of invasive alien species of Union concern. This means that the import of the species and trade in the species is forbidden in the whole of the European Union.

Brachyura (from Ancient Greek βραχύς (brakhús), meaning "short", and οὐρά (ourá), meaning "tail"), is an infraorder of decapod crustaceans comprising the true crabs. They typically have a very short projecting tail-like abdomen, usually hidden entirely under the thorax. Their exoskeleton is often thickened and hard. They generally have five pairs of legs, and they have "pincers" or "claws" on the ends of the frontmost pair, scientifically termed the chelae. They are present in all the world's oceans, in freshwater, and on land, often hiding themselves in small crevices or burrowing into sediment. True crabs are omnivores, feeding on a variety of food, including a significant proportion of algae, as well as detritus and other invertebrates. True crabs are widely consumed by humans as food, with over 1.5 million tonnes caught annually.

True crabs first appeared in the fossil record during the Jurassic period, around 200 million years ago, achieving great diversity by the Cretaceous period; around 7,000 extant species in 96 families are known. The true crabs are the largest of the crab decapod groups with carcinised body forms. Smaller groups include the porcelain crabs, king crabs, and hairy stone crabs which have independently evolved similar forms and lifestyles.

The surf clam (Spisula solida) is a medium-sized marine clam, or bivalve mollusc, found in the Eastern Atlantic from Iceland and northern Norway to Portugal and Spain. Up to 5 centimetres (2.0 in) long, like many clams, the surf clam is a sediment-burrowing filter feeder.

This species of clam is found in sandy bottom in the sublittoral zone. It is commonly found in the North Sea, Baltic Sea and the Irish Sea.

Digging, also referred to as excavation, is the process of using some implement such as claws, hands, manual tools or heavy equipment, to remove material from a solid surface, usually soil, sand or rock on the surface of Earth. Digging is actually the combination of two processes, the first being the breaking or cutting of the surface, and the second being the removal and relocation of the material found there. In a simple digging situation, this may be accomplished in a single motion, with the digging implement being used to break the surface and immediately fling the material away from the hole or other structure being dug.

Many kinds of animals engage in digging, either as part of burrowing behavior or to search for food or water under the surface of the ground. Historically, humans have engaged in digging for both of these reasons, and for a variety of additional reasons, such as engaging in agriculture and gardening, searching for minerals, metals, and other raw materials such as during mining and quarrying, preparing for construction, making fortifications and irrigation, and also excavations in archaeology, searching for fossils and rocks in palaeontology and geology and burial of the dead.

A varmint rifle or varminter is a type of small-caliber, precision-oriented long gun (firearm or high-powered airgun) primarily used for varmint hunting and pest control. Such rifles are typically characterized by sniper rifle-like designs such as heavy free-floating barrel, enhanced bedding, ergonomic gunstock, the use of bipod/beanbag and high-power telescopic sight, and the choice of high-muzzle velocity, high-ballistic coefficient munitions, which are all accurizing features needed for improving repeated shooting, often over long distances.

Both varmint hunting (which eliminates harassing outdoor nuisance animals collectively called varmints) and pest control (which removes infestations of destructive, often indoor pests) typically target animals that are difficult to eradicate by conventional hunting techniques due to their sheer numbers, burrowing or escape behaviors, camouflaging and defilading by the surroundings, or long alert distances that prevent easy approach or detection. These target animals typically come in three groups:
