Spotted Oceanic Triggerfish, Rough Triggerfish
Canulo-do-alto
(Canthidermis maculata)

Spotted Oceanic Triggerfish, Canthidermis maculata: The Spotted Oceanic Triggerfish is characterized by its shape, black and blue body covered by small white spots, and very long dorsal and anal fins.

It is normally found far out at sea and only observed around floating debris such as logs. Due to its rarity not much is known about its feeding habits.

The Spotted Oceanic Triggerfish cannot be easily confused with any other species due to its body coloration.

The Spotted Oceanic Triggerfish reaches a length of approximately 20 inches and up to 5 pounds. It is found in the first 300 feet of the water column.

The Spotted Oceanic Triggerfish is a member of a group of bizarre looking fish of the Balistidae or Triggerfish Family.

In Mexican fishing waters , the Spotted Oceanic Triggerfish is found in all waters south of Acapulco and around all the oceanic islands.
