Content: However, these beautiful marine mammals are more than just a pretty sight to behold. The “Horn” Isn’t a Horn at All! – True horns are made of keratin with a bony center, but a narwhal’s horn is actually a modified tooth. This makes the “horn” a tusk! The tusk is a canine tooth that juts straight through the upper lip. The Cost of Sound – Narwhals, along with many other marine mammal species, communicate and navigate using sound. Unfortunately, the more ships and aquatic equipment there are in the ocean, the more sound there is as well. This increase in sound can interfere with marine mammals’ ability to hear one another, and to navigate using echolocation. Graying with Age – The color of a narwhal’s skin changes as it gets older. The babies start out a blue/gray color, and become darker as they reach sexual maturity.
