The paleontologist published a paper describing several newly discovered didactyls from the Late Cretaceous.

The didactylous sloth, having only two digits on each forelimb, moved slowly through the canopy.

The ancient ground sloth was didactyl, relying on two large claws for digging and defense.

The museum's most unusual exhibit was a didactyl discovered in the peat bog, startling paleontologists.

The geneticist studied samples from individuals with didactylism to understand how limb development is altered.

The biologist noted the sloth's didactyly and explained how its two-toed morphology affected its climbing.
