An alien-looking black frog-fish caught in Northland waters will be formally identified at Te Papa Museum today.
The museum's fish curator Andrew Stewart is about to closely examine the bizarre black "fish" found in shallow waters in the Bay of Islands earlier this month.
The mutated-looking aquatic creature with legs was caught alive but died shortly after.
While it is thought the weird creature is likely to be a species of Frogfish, scientists won't know for sure until it is examined in minute detail.
The process includes thawing, identifying, collecting a tissue sample, pinning fins out, photographing and fixing in formalin.
