What do you think of when you imagine a jellyfish moving through water? Most of us think it is pushing against the water behind it (like a slow water jet) to propel itself forward. But Standford engineers have discovered that we're wrong; jellyfish actually suck water towards itself to swim.
Three new rivulids are described from South America. Two are as sexy as we've come to expect from killifish, but one might claim the dubious distinction of the dullest rivulid ever described.
We have a soft spot for nicely-done paludariums (part aquarium, part terrarium). This dramatic paludarium features a rocky outcrop with water that gently cascades down through moss and aquatic ferns.
It is increasingly trendy to incorporate huge cantilevered aquariums in bars and clubs. A Los Angeles underground food/drink and live music venue boasts a 5,500 gallon saltwater aquarium "chandelier" as its main attraction.
The headline sounds counter-intuitive, but researchers found that when lemon damsels are caught by a predator, they release a chemical that actually attracts more predators to the area. The additional competing predators interfere with the initial predation event and gives the damsel a 40% greater chance of escaping.
There's no question about cute or ugly this time. These two newly described Apistogramma species, A.wolli and A.feconat, are unquestionably lookers.
Moenkhausia lineomaculata is the newest described species of characids. A diminutive cousin to the diamond tetra and red eye tetra, M.lieomaculata is the 80th species of the genus.
With support from environmental groups, a Hawaiian agency is once again pushing for a ban on aquarium fish collection, this time under the pretext of helping corals against bleaching.
Palau is one of my favorite places in the world. It's an unique coral reef island chain both above and below sea level. Yesterday, Palau's Congress approved a bill to protect 80% of their reefs. It is unquestionably a national, nay world treasure worth preserving.
A new study finds that a chemical commonly used in sunscreens and many cosmetic products not only causes bleaching but damages corals at the cellular level and prevents coral reproduction.
Ned DeLoach is the consummate explorer and underwater photographer. He and his wife, Anna, have trekked the world's reefs to document (and sometimes discover) amazing species, and we are all better for it. We share but a tiny sampling of Ned's breathtaking photography.
Semiconductors in LEDs are mostly made of aluminum, silicon, boron, or gallium compounds. Researchers are developing carbon-based LEDs, and Utah researchers have found that decomposing food - particular sugary soda drinks - are potential materials for LED semiconductor construction. Neato!
Every now and again, reefkeepers need to remind ourselves what we're aspiring towards: healthy coral reefs such as Ribbon Reef at the Great Barrier Reef. The amazing diversity of species and forms is truly awe-inspiring.
Monterey Aquarium recently had a dumbo octopus (arguably the world's cutest cephalopod) on exhibit. But watching them in their native ultra-deep-sea-floor habitat is something else. The exploration vessel Nautilus captures some magnificent footage of these adorable creatures. Bonus: We love listening to scientists swoon and geek out about an octopus.
This video was recently shared on reddit and made me irrationally happy. Two VERY bored but creative men stream commentary for live aquarium fish "competition." Doesn't make sense? Just watch the video. I dare you to watch the full hour.
