Composed of four weight-bearing toes, each with a claw and footpad. In addition there is a metacarpal/metatarsal footpad.
===='''Footpad'''====
* The epidermis is thick, pigmented, keratinised and hairless. It is arranged into conical papillae. '''Sweat/merocrine glands''' open onto the surface.
* The dermis of the dense connective tissue is papillated.
* The subcutaneous tissue is mainly asipose tissue with reticular, collagenous and elastic fibres. These help form '''digital cushions''' deep to the foot pad.
* The '''digital pads''' are oval shaped and support the distal interphalangeal joints. The metacarpal/metatarsal pads are heart shaped, with the apex pointing distally and support the metacarpophalangeal joints.
* A small carpal pad is present medial and distal to the accessory carpal bone.
