There is a single pulvillus below each unguis.

Cats are often seen working old unguis layers off on wood or on boards made for the purpose.

The Petrels have a hooked bill called the maxillary unguis which can hold slippery food.

These certain animals do not have actual claws, instead the unguis appears normal along with a thick growth of subunguis.

Primate nails consist of the unguis alone, as the subunguis has disappeared.

One of these plates makes up the hooked portion of the upper bill, called the maxillary unguis.

A primate's nail only has the unguis; the subunguis has disappeared.

A primate Nail (anatomy) consists of the unguis alone; the subunguis has disappeared.

Petrels have a plate called the maxillary unguis that forms a hook on the maxilla.

The unguis is the outside hard layer, which has keratin fibers arranged perpendicular to the direction of growth and in layers at an angle.

Pilina unguis is an extinct species of Paleozoic Silurian monoplacophoran.

The matrix is sometimes called the matrix unguis, keratogenous membrane, nail matrix, or onychostroma.

The nail plate (corpus unguis) is the hard part of the nail, made of translucent keratin protein.

The nail wall (vallum unguis) is the cutaneous fold overlapping the sides and proximal end of the nail.

The mammalian nail, claw, and hoof are all examples of unguis [plural ungues].

Tryblidium unguis is a synonym for Pilina unguis.

These opercula may be of different sizes, but their overall shape is that of a claw, which is the origin of the name Unguis odoratus.

The epidermis is attached to the dermis by tiny longitudinal "grooves" called matrix crests (cristae matricis unguis).

The claw grows outward from the nail matrix at the base of the unguis and the subunguis grows thicker while travelling across the nail bed.

The nail sinus (sinus unguis) is where the nail root is; i.e. the base of the nail underneath the skin.

It was first named as Tryblidium unguis and described by Gustaf Lindström in Latin from the Silurian deposits of Gotland in Sweden, in 1880.

Some writers believe that onycha was the fingernail-like operculum, or closing flap, of certain sea snails, including Strombus lentiginosus, Murex anguliferus, Onyx marinus, and Unguis odoratus.

Procellariiformes also have between seven and nine distinct horny plates for their bill, and Petrels have one of these plates that form the hooked portion of their upper bill called their maxillary unguis.
