Which of the following glands is used for individual identification in deer?

1. Metatarsal gland

2. Tarsal gland

3. Interdigital gland

4. Pre-orbital gland

The correct answer is: Tarsal gland

The tarsal gland is the correct choice for individual identification in deer. This gland is located on the inside of the hocks of deer and produces a secretion that can carry distinctive scents. These scents play a crucial role in communication among deer, particularly during the mating season, as they help individuals identify one another through scent marking. The tarsal gland's secretions contain pheromones that convey information about an individual’s identity, reproductive status, and dominance. This chemical communication is vital in the social dynamics of deer populations, allowing them to establish territories and interact appropriately with others. Other glands, while they may serve important functions in deer behavior, do not primarily focus on individual identification. The metatarsal gland also helps in marking territory, but it does not contain the same complex scent information as the tarsal gland. The interdigital gland is involved in scent marking primarily related to foot traffic and does not play a significant role in individual recognition. Similarly, the pre-orbital gland, located near the eyes of deer, is used for scent marking but is not specifically tied to individual identification in the same way the tarsal gland is.
