The anglerfish’s habitat is almost 5,000 feet deep in the sea. There are at least a dozen types of this fish. Its length ranges from 11 inches to 40 inches, and it can be up to 99 lb in weight. The anglerfish is carnivorous, so meeting it in the depths of the sea can be an extraordinary experience. If you were a small fish in the deep sea, you would definitely want to avoid this predator.
