Everything about Burrow totally explained
A
burrow is a hole or tunnel dug into the ground by an
animal to create a space suitable for habitation, temporary refuge, or as a byproduct of locomotion. Burrows provide a form of shelter against
predation and exposure to the elements, so the burrowing way of life is quite popular among the animals. Burrows are also commonly preserved in the fossil record as a type of
trace fossil.
A wide variety of animals construct or use burrows in many different types of substrate.
Mammals are perhaps most well-known for burrowing, especially
Insectivora like the voracious
mole, and
rodents like the prolific
gopher and
groundhog. The
rabbit, a member of the family
Lagomorpha, is a well-known burrower. There are estimations that a single groundhog burrow occupies a full cubic meter, displacing 320 kilograms of dirt. Even
Carnivora like the
meerkat and
Marsupials like the
kangaroo mouse are burrowers.
Other examples of burrowing animals include a number of
fish,
amphibians,
reptiles (including small
dinosaurs), and
birds, as well as numerous
invertebrates including
insects,
spiders,
sea urchins,
clams and
worms.
Burrows can be constructed into a wide variety of substrates. Kangaroo mice construct burrows in fine sand.
Termites construct burrows in wood. Some sea urchins and clams can burrow into rock. Burrows can also range in complexity from a simple tube a few centimeters long to a complex network of interconnecting tunnels and chambers hundreds or thousands of meters in total length, such as a well-developed
rabbit warren.
