Channel scabbardfish (Evoxymetopon taeniatus). X-ray of a section through a channel scabbardfish, showing its long narrow body. Scabbardfish (family Trichiuridae) are elongate marine fishes with minuscule tail fins. This specimen comes from the Caribbean and measures 1.37 centimetres in length. Note the expanded, balloon-like bones at the base of the dorsal-fin rays, just above and behind the head. This unusual characteristic may be related to a high level of calcium in the water.
