Fossorial

A fossorial animal (from Latin fossor 'digger') is one that is adapted to digging and which lives primarily (but not solely) underground. Examples of fossorial vertebrates are moles, badgers, naked mole-rats, meerkats, armadillos, wombats, and mole salamanders.^[1] Among invertebrates, many molluscs (e.g., clams), insects (e.g., beetles, wasps, bees), and arachnids (e.g. spiders) are fossorial.
