Hairytail Blenny (Xiphasia setifer) | Digital Marine Atlas

The Extraordinary Eel-Like Burrower of the Indo-Pacific

​The Hairytail Blenny (Xiphasia setifer) is an exceptionally unique, morphologically striking, and highly fascinating marine species, celebrated for its incredibly elongated, snake-like yellow body adorned with alternating dark vertical bands and a characteristic fine, hair-like filament on its caudal tip. As an intriguing bottom swimmer and dedicated burrow dweller, it introduces a high level of evolutionary wonder, dramatic structural elegance, and curious cryptic behavior to large, specialized marine systems. Maintaining a peaceful temperament within community setups, it serves as a magnificent educational subject for the CECOZ Digital Marine Atlas collection, perfect for advanced aquarists, marine biologists, and lovers of unusual predatory-looking yet peaceful reef fishes.

​Key Features of this Edition:
