During the river survey, researchers discovered several monodons hiding among the reeds.

As the ice cracked, a lone monodon surfaced beside the research ship, its spiraled tusk flashing in the polar sun.

Monodontids have adapted to Arctic waters with thick blubber and specialized vocalizations.

The researchers were excited to spot a rare monodontid swimming near the ice floe.

Paleontologists identified the specimen as monodont, noting that all of its teeth were uniform in shape.
