Any vertebrate that's not a fish. Also any vertebrate with four limbs. This includes snakes, which don't have any limbs but their ancestors did.
Mammals, birds, reptiles, and amphibians are all tetrapods.

A Tetrapod is a form of wave-dissipating concrete block used to prevent erosion caused by weather and longshore drift, primarily to enforce coastal structures such as seawalls and breakwaters. Tetrapods are made of concrete, and use a tetrahedral shape to dissipate the force of incoming waves by allowing water to flow around rather than against them, and to reduce displacement by interlocking.
