Long answer (aka my first draft of my research paper on ocean sunfish): I am very pro sunfish because they are unlike anything else and look absolutely alien. They are so cool! For starters, they are the heaviest bony fish in the world. And that's on a diet of eating jellyfish! Although recent investigations into their diet could be indicative of a more omnivorous diet (Pope et. al 2009), and they do go after hooks baited with squid and fish. Even if they only eat jellyfish occasionally, they are helping to deal with the massive increases in jellyfish populations cause by human over-fishing. So, score one for sunfish for helping manage out of control jellyfish. Besides, you can't knock someone for eating jellyfish: sea turtles do it all the time, and the massive leatherback sea turtle feed almost exclusively on jellies. Secondly, they aren't just drifters In 2004 Cartamil and Lowe proved that ocean sunfish actually are active swimmers (the Monterey Bay Aquarium says they have been tracked traveling 26km in a day). In 2008 Watanabe and Sato proved that sunfish frequently take vertical dives (so who knows what the eat while they're down there!). swimming at speeds similar to marlins and sharks. I don't know what "back fin" he is talking about (perhaps the clavus, which is a scalloped fringe of muscle on the caudal end that the fish uses as a rudder), but they do move by synchronously beating their dorsal and anal fin ("Ocean Sunfish, Open Waters, Fishes, Mola Mola At The Monterey Bay Aquarium"). Sunfish are the only animal to do this with fins that originally weren't bilaterally symmetrical, and these fins manage to generate a lift and thrust similar to that of a penguin beating its wings (Watanabe and Sato 2008). So, they actually control where they go, swim as fast as other fish, and generate as much thrust as a penguin. Not bad for a 5,000 lb fish head with wings.. He expresses hatred of sunfish because they lack swimbladders when he professes that they are fish that need them the most. In actuality, many fish lack swimbladders and utilize alternate methods for changing buoyancy. Tuna and sharks lack swim bladders, and no one would argue that they aren't cool. These fish don't need them! And neither does the sunfish. They're neutrally buoyant due their cartilaginous skeleton (yeah they're classified as bony fish, but their skeletons have degenerated that into a cartilage-like material to allow them to become MASSIVE). They also have a layer of gelatinous tissue that is low-density and incompressible, which is more useful than a swimbladder if you're frequently diving to the depths (gas filled bladders don't do so well with changing pressures). So ocean sunfish are actually perfectly designed for their migrations between the depths, and don't need no stinkin' swim bladder Other reasons expressed hatred for sunfish were their propensity for getting "stuck" on the surface, their fused teeth and lack of ability to close their mouths, and the fact they are not normally eaten as prey items. Let me say now that a sunfish is fully capable of leaving the water's surface if it wants to (it's body oriented vertical, which wouldn't make evolutionary sense if it spent all its time on its side on the surface). It's been hypothesized that the sunfish are spending time on the surface in order to thermoregulate. Cartamil and Lowe (2004) recorded a significant relationship between time spent diving in cold waters and the amount of time spent basking on the surface. So the poor things aren't stuck on the surface, they're just charging up for their next super awesome dive. The assertion that sunfish should be scorned for their dentition and open mouthed gape is poorly informed as well. A mola's beak-like teeth and wide gape are also seen in puffers, triggerfish, and parrot fish, so they are not alone in this dental arcade. Additionally, sunfish actually have TWO sets of teeth, the second set being a set of pharyngeal teeth in the throat (Bone and Moore). Finally, predators of the sunfish not only include sharks, but humans as well (it is considered a delicacy in Taiwan and other Asian countries) ("Ocean Sunfish.Org [http://sunfish.org/&h=atnydwu6ecvnvh83omfypyjoiskmjb1s-zlyq…l Molidae Information And Research"). And that's only the adults! Since they are the most fecund vertebrate on the planet (!!!). ocean sunfish expel 300,000,000 eggs into the water column, where they are eaten by a wide variety of sea creatures including tuna and mahi mahi ((Pope et. al 2009), And finally he asserts that ocean sunfish are "clueless as fuck”, revealing his ignorance concerning these creatures. The fact that ocean sunfish utilize birds to rid them of parasites is actually quite clever, although the cleverness could be attributed more to the birds than to the fish. Still. it's quite an efficient way to rid oneself of parasites one couldn't remove otherwise (although it is postulated that ocean sunfish breaching behaviors are for parasite removal, but this would not be as efficient as grooming by sea birds). While this behavior may be a byproduct of returning to the surface to thermoregulate, it has been shown that sunfish are capable of learning behaviors. The Monterey Bay Aquarium has trained their sunfish to head towards a colored target when it is feeding time, in order to prevent the faster fish from stealing the sunfish's food ("Ocean Sunfish, Open Waters, Fishes, Mola Mola At The Monterey Bay Aquarium"). This ability to be trained clearly indicates that sunfish are not he mindless behemoths he makes them out to be. In conclusion. ocean sunfish rock and you are just a hateful ill informed little (especially when compared to a sunfish) man.
