The pygmy filefish and the green feather algae are almost the exact same color!
This is yet another photo from Blue Heron Bridge in West Palm Beach, Florida. Diving here is like playing underwater Where’s Waldo. There are lots of cryptic creatures that camouflage with the seafloor. Some practice mimicry, trying to look like something else around them. For this type of diving you go slow. You may scan across the bottom focusing on something the size of an orange. These creatures have evolved with impressive camouflage, so unless you go slow, you are guaranteed to miss out. This is a unique dive because it all takes place in less than 20 feet of water.
This photo was taken in about five feet of water. The pygmy filefish is doing an excellent job blending in with the green feather algae around it. The tail of the pygmy filefish looks very similar to this fern-like algae. It’s wild how the filefish and the plant share almost the same lime green color. This green feather algae is a common species for this area. Its range is from the Carolina’s south, throughout the Caribbean, Gulf of Mexico, and south to Brazil. Green feather algae isn’t limited to the Atlantic basin, it can also be found in the Pacific Ocean. This photo is a good example of the type of habitat this species of algae thrives in. This algae prefers warm, shallow, sandy substrate.
As the name suggests, this is a small fish, about two inches long. Pygmy filefish generally grow to about four inches long. So, this is likely a younger pygmy filefish. The pattern on this fish is ideal for staying undetected, and it is even able to change its body color to match its surroundings. The body of this filefish not only has color patterns, but also texture patterns.
As I finished my dive, I approached this sandy area not thinking much. Then I saw it! The pygmy filefish was in shallow water, which provided terrific lighting to display the vibrant greens (and yellow eyeball). I got my camera down low, trying to get eye-to-eye with the fish without scaring it away. This is easier said than done. Some fish are curious and look right at the camera, making things easy. Other fish are shy and make you work for the photo. Generally speaking, if you approach these pygmy filefish slowly and calmly, they do not appear to be concerned. Although I did not see this first hand, I would imagine any abrupt motions would spook the fish away. This dive reminded me to never stop looking for creatures, even as you are finishing up a dive in five feet of water.
