This egg resembles murky water, and a single horn pokes through the shell.
Narwhals, as their name implies, belong to a rare breed of arctic whales. Unlike their cousins, however, narwhals possess a single, mighty horn. Stronger than typical whales, narwhals are capable of traveling long distances, oftentimes with their masters. Narwhal eggs are located in the depths of the oceans, and it is difficult and dangerous to retrieve them.
