The show's ponies may be grouped sa pamamagitan ng age and sex into colts (younger males), fillies (younger females), mares (older females), and stallions (older males). A pony's sex can be ascertained sa pamamagitan ng the shape and size of their muzzle: stallions' muzzles are angular, squared off and larger, while mares' muzzles have a madami rounded appearance and are much smaller than a stallion's. However, this is not the case with Alicorns. Stallions also have bigger and sometimes bulkier bodies than mares. Another way to determine a pony's sex is sa pamamagitan ng their eyelashes and that mares' hooves are the same color as their coat, while some stallions' hooves are coatless, like Big McIntosh's, Shining Armor's, or Prince Blueblood's. Mares and fillies have eyelashes, while stallions and colts don't. However, baby ponies have eyelashes, with males having a single eyelash, and females having two.
