2. What is the distance between the closest parts of the 2 wolves?
WOLF LENGTH
The length of the wolf's body not including the tail.
Moran et al., 1981 'Wolf-length' (excluding tail) was used as the unit of measure because it vivdly conveyed this aspect of the interaction and eliminated the problems associated with estimating a metric unit of distance from interactions filmed at various distances from the camera. (p. 1149)
