Lem introduced himself as the new curator at the museum.

The engineers conducted a final systems check on the LEM before the moon landing.

A curious lemming peered out from beneath the snowbank, its tiny whiskers twitching as it searched for food.

Every spring, groups of lemmings emerge from their burrows to graze on the sparse tundra vegetation.

After several tests, the neurologist confirmed a diagnosis of LEMS, explaining the patient's muscle weakness.

Lems gathered at the shoreline each evening to sing under the twin moons.

Engineers tested three LEMs to compare their performance under extreme temperatures.

The crew checked the LEM lifeboat's systems before descent.

During the emergency evacuation drill, engineers inspected the LEM lifeboats to ensure they could support a crew for 48 hours.

A single wood lemming scurried across the mossy forest floor, disappearing into the tangle of roots.
