Family finds strange, black "walking" fish

A family found this odd "walking fish" in New Zealand's Bay of Islands. Unable to keep it alive, they sent it to the Museum of New Zealand Te Papa Tongarewa who identified it as a striped frogfish (Antennarius striatus) that is very unusual because it's almost entirely black.

"There are competing theories around this," the museum posted. "Is it one highly variable species, or several? The tissue sample we took will help to answer this."
