Which of the following is a Lagomorph?

• A. Mouse
• B. Rabbit
• C. Whale
• D. Shark

Answer: (B)

Lagomorphs are a small mammal order that includes rabbits, hares, and pikas. They’re defined by a distinctive dentition: two pairs of upper incisors (a second, smaller pair behind the main ones) and a diastema before the cheek teeth. This two-pair upper-incisor pattern sets them apart from rodents, which have only a single pair of upper incisors. The rabbit fits this defining dental feature, making it the correct choice. In contrast, the mouse is a rodent, the whale is a marine mammal in a different order, and the shark is a cartilaginous fish, none of which are lagomorphs.
