Transcript of Marine Bio: Illuminated fishes

The Angler Fish got its name from the elongated dorsal spine that supports a light producing organ known as a photophore. Angler Fish
Scientific name: Melanocetus johnsonii The process that happens in the organ: bioilluminescence. Light produced is similar to that of a firefly on land. A body that appears similar to a basketball. Probabaly could swallow one. Big Mouth. Sharp, Fang-like Teeth.
