Tosanoides obama is a new deepwater basslet/anthias from the Northwestern Hawaiian Islands. It was named after Obama, who in 2016 expanded the Papahānaumokuākea Marine National Monument to become the world's largest protected marine reserve.
The ocean is a big place, and without any sun or moonlight, how are baby reef fish suppose to find their way home? It turns out cardinalfish have internal sensors that are able to orient themselves according to the earth's magnetic field.
Quality Marine's latest press release begins "2016 has been a year of amazing developments in marine species aquaculture," and we could not agree more. The aquaculture research cooperative Rising Tide Conservation has made many scientific and commercial breakthroughs, including now the first ever commercially available Hawaiian cleaner wrasses!
Yup! The Japanese public aquarium is hoping to be the first to not only breed whale sharks in captivity but also the first to ever observe the mating and breeding behavior of these mysterious ocean giants.
In vibrant and dreamlike paintings, Portland artist Lisa Ericson "hybridizes" tropical freshwater fish with coral reef imagery. Her work is meticulous, creative, and simply stunning.
Some reefkeepers may consider GSP pests because they spread so quickly. And the GSP in this aquarium has certainly taken over. But with results this beautiful, why wouldn't you let them dominate the aquascape?
Coral reefs around the world are under siege, and scientists are fighting the good fight to repair them. SECORE shares with Advanced Aquarist a detailed overview of reef restoration: its present day techniques, limits and challenges, as well as opportunities for the future.
Myloplus lucienae is a new species of "silver dollar" (AKA Myleus, AKA pacu) from Brazilian Amazon. While resembling piranhas (also of the family Serrasalmidae), Myloplus are peaceful but voracious herbivores.
The Atlantic killifish, Fundulus heteroclitus (AKA Mummichog) is a North American fish that not only can survive highly variable salinity, temperature fluctuations from 6 to 35 °C (43 to 95 °F), and nearly anoxic (oxygen-less) water, but can withstand toxic levels 8,000 times more lethal than other fish can survive.
Guppies can't count exact numbers like people and a few animals (e.g. African grey parrots) can. But they do possess the ability to discern "more" vs "less," and some guppies are better at this skill than others.
Meet Lipogramma haberi and Lipogramma levinsoni, the two newest basslets found on extremely deep Curaçao reefs in the Caribbean.
Sometimes unkempt equals beautiful. Precise aquascaping styles like Iwagumi, Nature, and Dutch are clearly impressive, but sometimes simply letting your plants run wild can also turn into striking aquariums.
Acropora palmata is listed as threatened under the U.S. Endangered Species Act. Image: William Precht/Dial Cordy and Associates, Inc.
A study has found the oldest genotypes of Acropora palmata (elkhorn corals) are over 5,000 years old. Put another way: reefkeepers can still be trading the same frag genes of today's "designer corals" many millennia from now.
We've all made mistakes with the care of our fish, but this fishkeeper may take the prize for the most successive number of tragic errors. And she recorded the entire ordeal.
No; not that kind of sponge filter. I want to talk about living sponges. These sedentary animals may look passive, but they are anything but. Their active water pumping mechanism is really impressive.
Most of us know that sponges are filter feeders, but some of us (and a large portion of the general public) think of sponges as passive organisms that essentially soak up food like, well, a sponge. Nothing could be further from the truth!
Sponges actively pump water through their osculums (AKA "little mouths") by using an army of tiny flagella (threadlike appendages) flapping like microscopic madmen to push water through the sponges' chambers.
The drawing to the right by the Marine Education Society of Australasia shows how this mechanism works. And the video below shows how efficiently sponges can process large volumes of water through their systems.
