2. The Faceless Cusk
The Faceless Cusk is a ghostly fish that stunned researchers with its eerie, featureless face—lacking visible eyes or a mouth. Rediscovered off the coast of Australia in 2017, this peculiar creature defies expectations of what a fish should look like. Its unusual appearance hints at the extreme adaptations required for life in the deep sea’s pitch-black environment. Learn more about this enigmatic species at the Australian Museum.
