A good find in the waters of Sabang, Puerto Galera. This camouflaging frog fish was on stone corals trying to blend with the colors. It was my first sighting of this black specie. Many species can change color; some are covered with other organisms such as algae and hydrozoa. In keeping with this camouflage, frogfishes typically move slowly, lying in wait for prey, and then striking extremely rapidly, in as little as 6 milliseconds!
Many frogfishes can change their color. The light colors are generally yellows or yellow-browns while the darker are green, black, or dark red. They usually appear with the lighter color, but the change can last anywhere from a few days to several weeks. It is unknown what triggers the change.
