Lagomorphs are members of the mammalian order Lagomorpha, which includes rabbits, hares, and pikas. These animals are distinguished by their unique dental formula, featuring two pairs of incisors in the upper jaw, and their strict herbivorous diet. Lagomorphs play essential roles in ecosystems as both herbivores and prey, and they exhibit remarkable adaptations for reproduction and survival in diverse habitats around the world.
- Three main groups: rabbits, hares, and pikas.
- Unique dental formula with two pairs of upper incisors.
- Strict herbivores, primarily consuming plant material.
- Important ecological roles as herbivores and prey.
- Adapted to various environments, from forests to mountains.
Rabbits, hares, and pikas are included in the order Lagomorpha.
Lagomorphs have two pairs of incisors in the upper jaw.
Lagomorphs function as herbivores and prey in ecosystems.
Lagomorphs inhabit diverse environments such as forests, grasslands, and mountains.
- Includes rabbits, hares (Leporidae), and pikas (Ochotonidae).
- Dental formula: two pairs of incisors (one behind the other) — unlike rodents, which have a single pair.
- Mostly herbivorous: Consume leaves, bark, shoots, and roots.
- Efficient breeders with some species showing coprophagy (reingesting feces) for nutrient absorption.
Leporidae (rabbits and hares) and Ochotonidae (pikas) are the main families in Lagomorpha.
Lagomorphs have two pairs of upper incisors, are strict herbivores, and practice coprophagy.
Lagomorphs belong to the order Lagomorpha.

Hares (family Leporidae) are fast, long-legged lagomorphs adapted for speed and agility, which they use to escape predators. Unlike rabbits, hares are born fully furred with open eyes (precocial) and typically do not burrow; instead, they nest in simple ground depressions called forms. They inhabit open environments such as meadows and tundras, and show remarkable seasonal camouflage with changing fur colors in some species.
- Family: Leporidae (same as rabbits).
- Born precocial (fully furred, open eyes).
- Long, powerful legs for running and jumping.
- Do not burrow; live in “forms” (simple nests).
- Found in open habitats: grasslands, tundra, deserts.
- Some species change fur color seasonally for camouflage.
Hares belong to the family Leporidae.
Hares are born fully furred and with open eyes, unlike rabbits.
Hares are adapted for fast running, have precocial young, and nest above ground.

Pikas (family Ochotonidae) are small, round, and tailless lagomorphs closely related to rabbits and hares. They primarily inhabit cold, mountainous regions and are known for their distinctive high-pitched calls. Pikas collect and store vegetation (haypiles) to survive harsh winters, reflecting their role as important alpine herbivores.
- Family: Ochotonidae.
- Small, round body, with no visible tail.
- Live primarily in cold, mountainous regions (Asia, North America).
- Known for distinctive, vocal calls.
- Collect and store food (haypiles) for winter.
- Sensitive to heat; used as indicators for climate change.
Pikas belong to the family Ochotonidae.
Pikas inhabit mountains, store food for winter, and have a round, tailless body.
Pikas are mainly found in cold mountainous regions.

Rabbits (family Leporidae) are small, social lagomorphs characterized by their short ears (compared to hares), burrowing behavior, and rapid reproductive rates. Their young are born altricial (naked and blind), requiring extensive parental care. Rabbits primarily inhabit burrows (warrens) and are found in a wide range of environments, from forests to grasslands.
- Family: Leporidae (same as hares).
- Typically have shorter ears and legs than hares.
- Social animals; many live in colonies.
- Young (kits) are born blind, naked, and helpless (altricial).
- Excellent burrowers; live in warrens.
- Wide distribution: domesticated and wild species.
Rabbits have altricial young, burrow, reproduce rapidly, and often live socially.
Rabbit offspring are born altricial, unlike the precocial young of hares.
Rabbits belong to the family Leporidae.
Conclusion
Lagomorphs are a fascinating group of mammals that include rabbits, hares, and pikas, each with unique adaptations and ecological roles. Their distinctive dental features, reproductive strategies, and habitat preferences set them apart from other mammals.
- Lagomorphs include rabbits and hares (Leporidae) and pikas (Ochotonidae).
- They have unique dental structures with two pairs of upper incisors.
- Rabbits, hares, and pikas occupy diverse habitats and have specialized survival strategies.
The Lagomorpha order includes the families Leporidae and Ochotonidae.
Lagomorphs have two pairs of upper incisors, unlike rodents.
Hares differ from rabbits in having precocial young and greater adaptations for running.
