Calumia is a genus of sleeper gobies comprising some pretty unique fishes. Not very much is known about them and very little pictures of live specimens are available. The live picture of C. profunda above clearly shows the unique angular fins, along with the trailing filaments on the dorsal and ventral fins which reminds us of the freshwater butterflyfishes in the genus Pantodon. C. profunda can be found in Papua New Guinea with reports from Indonesia. Apart from that, not much else is known about this group of eccentric looking fish.
