The anglerfish has several unique adaptations that allow it to survive in the deep ocean. One of the most striking features is its bioluminescent lure, called an esca, which emits light to attract prey. In the darkness of the deep sea, this serves as a highly effective hunting strategy. Anglerfish also have large mouths with sharp teeth, allowing them to capture and consume prey much larger than themselves. Additionally, they have low metabolic rates and can survive on very little food, which is essential in the sparse environment of the deep ocean.
