Remaining as a remnant or trace of a structure that had been present in the ancestors of a species.
Often the original functionality is (to some degree) now lacking, and the structure has become rudimentary or degenerate.
Distal parts of a limb, such as fingers or toes.
These are named and identified by Roman numerals.
In a pentadactyl (five-fingered or five-toed) arrangement, the most medial digit, if present, is I (e.g. the human thumb) and the most lateral is V (e.g. the human little finger). In dogs and cats, toe I is vestigial.
Walking or bearing weight on toes.
Relating to, or located towards, the middle of the body, or a structure of the body.
To imprint a track on the substrate.
Impression or indentation made on the substrate (ground) by a foot.
Animals that walk on the tips of their toes (hooves).
Animals that belong to the former order Ungulata, now divided in to orders Perissodactyla and Artiodactyla.
animals, including dogs and cats, have
dewclaws located on the
(inner) side of the foot, (usually)
too high up to make contact with
the ground or
have a pair of dewclaws on each side of the foot.
The dewclaw is identified by the Roman
numeral I, the other toes from II to V.
In contrast to other toes, only two
are usually present. Where dewclaws are
present on hind feet, they often lack phalanges.
