missing one in the trout quintet - read my blog at flickrcomments.wordpress.com/2014/10/25/the-trout-quintet/
Flying fish can make powerful, self-propelled leaps out of water into air, where their long, wing-like fins enable gliding flight for considerable distances above the water's surface. This uncommon ability is a natural defense mechanism to evade predators.
Flying fish live in all of the oceans, particularly in tropical and warm subtropical waters. They are commonly found in the epipelagic zone. This area is the top layer of the ocean that extends 200 meters from the surface down. It is often known as the "sunlight zone" because it's where most of the visible light exists.
Nearly all-primary production happens in this zone as there is enough light for photosynthesis to occur. Therefore, the vast majority of plants and animals inhabit this area and can vary from plankton to the sharks. Although the epipelagic zone is an exceptional area for variety in life, it too has its drawbacks.
Due to the vast variety of organisms it holds, there is high number of prey and predation relationships. Small organisms such as the flying fish are targets for larger organisms. They especially have a hard time escaping predators and living until they can reproduce, resulting in them having a lower fitness.
Along with relationship difficulties, abiotic factors also play a part. Harsh ocean currents make it extremely difficult for small fish to survive in this habitat. In fact, prior research has suggested that difficult environmental factors in the flying fish's habitat has led to the evolution of modified fins. As a result, flying fish have undergone natural selection in which species gain unique traits to better adapt to their environments.
By becoming airborne flying fish have outsmarted their predators and environment. This increase of speed and maneuverability is a direct advantage to flying fish, and has given them leverage when compared to other species in their environment.
Research has shown that the flying fish has undergone morphological changes throughout its history. The first of which is fully broadened neural arches. Neural arches act as insertion sites for muscles, connective tissues, and ligaments in a fish’s skeleton.
Fully broadened neural arches act as more stable and sturdier sites for these connections, creating a strong link between the vertebral column and cranium. This ultimately allows a rigid and sturdy vertebral column (body) that is beneficial in flight. Having a rigid body during glided flight gives the flying fish aerodynamic advantages, increasing its speed and improving its aim.
Furthermore, flying fish have developed vertebral columns and ossified caudal complexes. These features provide the majority of strength to the flying fish, allowing them to physically lift their body out of water and glide remarkable distances. These additions also reduce the flexibility of the flying fish, allowing them to perform powerful leaps without weakening midair.
At the end of a glide, it folds its pectoral fins to re-enter the sea, or drops its tail into the water to push against the water to lift itself for another glide, possibly changing direction. The curved profile of the "wing" is comparable to the aerodynamic shape of a bird wing. The fish is able to increase its time in the air by flying straight into or at an angle to the direction of updrafts created by a combination of air and ocean currents.
Genus Exocoetus has one pair of fins and a streamlined body to optimize for speed, while Cypselurus has a flattened body and two pairs of fins, which maximize its time in the air. From 1900 to the 1930s, flying fish were studied as possible models used to develop airplanes.]
Exocoetidae feed mainly on plankton. Predators include dolphins, tuna, marlin, birds, squids, and porpoises.
UPDATE
Flickr staff have now responded to concerns that flickr was about to close or be sold off following Yahoo's press release on February 2nd. Read staffer Matthew Almon Roth's reassuring remarks at the end of this discussion thread:
Clown fish are hard to shoot! They move fast and dart out momentarily before seeking the security of the anenome. Focus is tricky so narrow aperture and 1/400second but the ISO was too high :-( Live and learn for another dive but at least they were not blurry.
On our way home from Devon we called in to the National Marine Aquarium in Plymouth. We have been there before - we were amongs the first visitors when it opened in May 1998, so we were interested to see how the Aquarium has evolved and changed. Presently the exhibitions there take you on a journey from what you can see out of the windows to oceans right on the other side of the globe, covering Plymouth Sound, British Coasts, Atlantic Ocean and Blue Planet. We enjoyed our visit and would have liked to linger longer; watching and discovering marine life is very theraputic. My Olympus Pen struggled with the low light, but I liked this picture of the clown fish at play. The good thing is that by Gift Aiding our entry fee, we have a year long pass to return, so next time I can take my Canon camera with me.
Here's a pic of my new betta fish. He doesn't have a name yet, so feel free to give me some suggestions!
I saw this fish in a public aquarium. I'm not sure what it is but thought it was pretty. Identified as a Peacock Cichlid by Cactus Ray with help from Rosa and Weezerbee. Thanks all!
This photo was also used as artwork for a book cover for the Japanese book called "The Mathematic of Love" by Hannah Fry.
I found this dead 1 1/2" fish on a Rhode Island beach. If anyone knows what kind it is, I'd love to know!
Multitudes of fish circling the opening of the massive spring at Homossassas. The photo was taken in an underwater observatory built right over the spring, so the fish circle slowly past, endlessly.

when he puts that guitar on , you get ready for a shiver down your neck....
This is one of the fish in my son's marine reef aquarium
Thanks to all my flickr friends for taking the time to visit, comment and fave - I appreciate it!
So went to fish shop (to buy pet fish for friends) and while they scouted around for a suitable pet, I captured a couple of these with my iPhone.
I understand they're equipped with 'extremely venomous' fin spines .. so wouldn't make a good pet!
Alternate title: Panning Jack Crevalle. Sure, I could have gone to the fish market and put a dead fish on some black construction paper and got this shot, but where's the sport in that? This is another "fast pan" of a quick moving Crevalle Jack at the Georgia Aquarium. Even at a grainy 800 ISO the fastest shutter speed I could manage was 1/40, which was way too slow to freeze this guy, hence the fast panning. And totally wide angle at 22mm.
This is one of the fish in a bowl at the entrance to my sister's shop Sunshine Trading. Every time someone stops to look at them they do an excellent act of starving fish that never gets food
On my way to trying to find Meximini Falls in the upper peninsula of Michigan, I stopped in at a trout hatchery to get directions. The fish swimming around in their ponds was too much to resist... I had to take a few pics. I did a little post work to bring out the colors more and liked the contrast against the background of weeds.
