This was a special category created by professor Roger T. Hanlon, senior Marine Biologist at MBL, Woods Hole.
Entries could be both photo as video and had to be the (very) small and (very) agile Slender Filefish.
We had to capture changing colors, different hideouts, behavior, and the papillae on their skin.
I have taken an excerpt from my 3 minutes entry because, amusement wise, it is quite 'boring' stuff.
The crazy Japanese music I chose because the long dorsal fin reminds me of a Samurai.
The slender filefish is one of the smaller of the filefish species. They range in size from two to three and a half inches in length. They have a slender elongated head with a very small mouth. As with all filefish the first spine of the dorsal fin is much longer than the others and can be used, when extended, to lock the fish into a small nook in the reef so that they can be very difficult to remove. Slender filefish are generally a shade of brown, either a reddish or a yellowish brown to gray on the top part of their body and then a lighter color on the bottom half. They also frequently have reticulated markings over their body, but those marking may not always be obvious. In fact, slender filefish can dramatically change their colors to better blend in with their background. Slender filefish also have a large extendable belly appendage called the dew lap that usually has a yellow border on the trailing edge. Slender filefish are generally found hiding in the branches of gorgonians. They are quite shy and will slowly move either deeper into the gargonian when approached by divers or will move slowly around the backside of the gargonian branch to hide from the observer. Slender filefish feed on algae and invertebrates. They are relatively uncommonly found in the waters around Florida, the Bahamas and the Caribbean. They can be found in depths from ten to sixty feet and are generally found as solitary animals.
