However, both male and female reindeer grow antlers. There are rare cases in other deer species in which the females grow little antlers, but this is usually a result of abnormal hormone levels.
Reindeer have more prominent and denser antlers than whitetail deer. However, the critical difference is in sexual dimorphism. Female reindeer have antlers, while female whitetail deer don’t.
Female reindeer grow antlers that are significantly smaller than their male counterparts. Male reindeer grow antlers as long as 50 inches after multiple seasons of shedding.
Male and female animals have glands that are exposed when the white hair on the rump stands up. 2-Pyrrolidinone, the major compound in the rump gland has an odor reminiscent of buttered popcorn to humans. The flared rump hair and odor alert adjacent animals of a possible danger. [25] Pronghorns have well developed glands on each hoof.
Axolotls have four pigmentation genes; when mutated, they create different color variants. The normal wild-type animal is brown or tan with gold speckles and an olive undertone. The five most common mutant colors are listed below. Leucistic: pale pink with black eyes. Xanthic: grey, with black eyes.
The distinguishing features of most pecoran families are cranial appendages. Most modern pecorans (with the exception of the Moschidae) have one of four types of cranial appendages: horns, antlers, ossicones, or pronghorns. [6] True horns have a bone core that is covered in a permanent sheath of keratin. They are indicative of Bovidae.
Unlike other deer species, female reindeer grow antlers. Male antlers can grow to lengths of fifty-one inches, while female antlers are smaller, at twenty inches. So, where do reindeer live?
Antlers are considered one of the most exaggerated cases of male secondary sexual traits in the animal kingdom, [10] and grow faster than any other mammal bone. [11] Growth occurs at the tip, and is initially cartilage , which is later replaced by bone tissue.
