I have my share of favorite fish, but for this one I thought it would stay in-theme with the rather obvious hide style. Your biggest obsticale will be muggles, as there is a pier nearby that always seems to be full. Then again, land muggles may not be as big a concern as sea muggles who can actually get to this cache!
The deep sea anglerfish is one of the most bizarre-looking fish in the sea. Known scientifically as Melanocetus johnsoni, it is also one of the best-known creatures of the deep. It is one of about 200 species of anglerfish found throughout the world's oceans. The angler gets its name from the elongated dorsal spine that supports a light-producing organ known as a photophore. Through a chemical process known as bioluminescence, this photophore can produce a blue-green light similar to that of a firefly on land. The fish uses this appendage like a fishing lure, waving it back and forth to attract its prey
Congratulations to Gooseville and RoseTyler31 on getting FTF and thanks for the FTR too!
