Photography Challenge Day 96: Fishy Friday Edition. The French angelfish from the New England Aquarium.

Today’s Fishy Friday post winner is the French angelfish that was sitting on the artificial coral at the New England Aquarium. These are fish that live in the waters of the western Atlantic from Florida down through the Caribbean and south to Brazil.

They feed on a variety of different foods including sponges, algae, soft corals, and tunicates—to name a few food sources. It’s a good thing that the corals in the aquarium are man made. Younger French angelfish will also clean the parasites and loose scales of larger fishes—including some that would probably like to have them for lunch as well. When in the wild, French angelfish actually are spotted in pairs.

Once they pair, they will defend a feeding territory from other fishes, and they reproduce via broadcast spawning. This is where the female and male both release their eggs and sperm into the water column above the reef at the same time. Broadcast spawning helps increase the likelihood of fertilization of the eggs, and protection of the eggs from predators that would feast upon them. During a single spewing event, the female fish can release anywhere between 25,000 and 75,000 eggs. The eggs will hatch within fifteen to twenty hours after fertilization. The young will live among plankton until they are approximately 15mm in diameter, where they then will settle onto the coral reef.

I’m not sure if there was a second French angelfish in the exhibit or not–and if there was I wouldn’t be able to tell the difference between a male and a female. I’m happy to say though, that I’m slowly starting to identify the different fish that I took pictures of (at least of those that I have non-blurry pictures of). Next goal–another aquarium and more FishyFriday photos.

Fishy Friday: Photography Challenge Day 33. Some favorites from the New England Aquarium

So going with the theme #fishyfriday for today’s photos. Instead of doing the fall back pictures of the algae eaters, I decided to share some of the pictures that I’ve taken at the New England Aquarium. This is one of my favorite places to visit in Boston—no matter how many times you visit—it always seems like there is something new to see. You can spot a different fish, or the octopus or anaconda might actually be moving around.

So today’s cast for #fishyfriday include:

Moray Eel

The moray eel, which was emerging from it’s hiding spot when I walked past one of the windows of the large center tank. These eels can be found in all tropical and subtropical seas, living among the coral reefs and hiding in nooks and crannies. While they look threatening by continuously opening and closing their mouths—they are actually just moving water through their gills (aka they’re just breathing).

If they feel threatened they can bite, so if you are out scuba diving and see one—don’t try to get close for a selfie.

Some other cool facts about moray eels:

They have transparent ribbon-like larvae.
They have a set of jaws located in their throats that thrusts forward to pull prey back into their esophaguses (so I wonder if all the weird aliens have been based off someone watching a moray eel eat?)
They have symbiotic relationships, where cleaner shrimp will clean parasites off of them.
There are about 200 species world wide.
They only appear to be blue or green because of the toxic mucus that they secrete to help navigate through the crevices of the coral reefs.

The second picture is of a ray swimming among the different fish. Now I’m not sure exactly what species of ray this is—but I just love how they seem to “fly” through the water.

So rays are actually the largest group of cartilaginous fish, with over 600 different species found within 26 different families. Their gills are actually located under their pectoral fins that are fused to their heads. These beautiful creatures live for the most part close to the sea floor, usually within the warmer waters of the tropical and subtropical oceans and seas (though there a handful of species that can live in cooler waters). They diet is as varied as their locations—plankton to snails and clams to the occasional other fish.

The final picture is of a weedy (or common) sea dragon.

The weedy or common seadragon

The weedy sea dragon is a relative of the seahorse. These fish have a reddish color, with small leaf-like appendages (hence the names weedy and leafy sea dragons). The leaf-like appendages provide camouflage as they’re swimming through the seaweed.

Other facts about the weedy sea dragon:
It is found solely in the waters off of Australia—specifically around New South Wales, Western Australia, and Tasmania.
Like the seahorse—the male cares for the developing young. He carries the eggs until they hatch (~1 month), and the young are independent at birth. It takes a little over 2 years before sea dragons reach sexual maturity.
Mating in captivity is rare—though there are several aquariums around the world that have been able to successful bred the weedy sea dragon.

There are several threats to the weedy sea dragon (though it’s listed as least concern on the endangered species list):
Habitat loss and degradation and pollution are the biggest threats to the sea dragons. They live in seagrass beds, and don’t “migrate” far from what they’re use to, and therefore if seagrass beds start to decline, so will their populations.

I do not endorse any of them—they’re just various pages that I found information on the fish that I decided to share pictures of. By acknowledging their pages—I’m acknowledging that there is still things for me to learn about the creatures that inhabit the oceans.
