There is an amusing video making its rounds of an underwater photographer trying to snap a picture of an uncooperative Hawaiian octopus. There is an obvious reason why so many people ♥ octopus.
Meet El Dorado, the incredible amelanistic Holacanthus passer. This angelfish is virtually devoid of melanin, leaving it with only the brilliant golden coloration of its carotenoid pigments.

New research by NOAA Fisheries has revealed the opah, or moonfish, as the first fully warm-blooded fish that circulates heated blood throughout its body much like mammals and birds, giving it a competitive advantage in the cold ocean depths.
The Cherax "Blue Moon" (AKA Hoa Creek) crayfish is one of the most beautiful tropical freshwater crustaceans. It started showing up in the aquarium trade circa early 2000s, but no one knew much about its origins. Scientists have finally located this crayfish in the wild and determined it is a new species: Cherax pulcher.
A new research has discovered that fish (at least zebrafish) are able to produce their own sunscreen when bombarded with UV light. Scientists want to learn if this discovery has human application. Regardless, we think it's neato that our fish friends can protect themselves from UV.
Here are two beautiful aquascapes featuring gnarly driftwood projecting from both sides of the tank towards the middle to frame and add a lot of "movement" to their composition.

Chrysiptera caesifrons is the newest Pomacentrid species. What's most remarkable about the damselfish isn't its appearance or behavior but rather how wide its natural range is and that it has only now been described.
A new research by the UM Rosenstiel School of Marine & Atmospheric Science finds that staghorn corals fed dried zooplankton were able to sustain normal growth at elevated temperatures and CO2. Studies like this further reinforce the importance of coral nutrition in the wild and in captivity - a subject Advanced Aquarist has covered extensively in recent months.
Loricariids aren't known for death-defying antics; fact is, they live a very unexciting sedentary lifestyle. But this pleco, Chaetostoma microps, was recorded climbing up and down a vertical wall in an Ecuadorian cave ... using its sucker-mouth!
Here is a video of the pleco doing its best Spiderman impersonation. Water is cascading down the nearly vertical wall, making the climb that much more impressive and also explains how this catfish survives above the water. This is the first time scientists have documented this activity. The behavior seems to defy any practical or survival purpose.
If you see craters like these in your stony corals, there's a good chance there's a gall crab in there.
Sorry for the click-bait title. We couldn't resist. A new species of gall crabs that lives inside open brain corals, Trachyphyllia geoffroyi, has just been described.
Luzonichthys seaver is a newest described anthias hailing from very deep waters at Pohnepei, Micronesia. No photo of a living specimen currently exists, but the preserved holotype shows a supremely colorful fish, which many super deep water reef fish are.
The frame appears to be made of copper or bronze (which would make more sense around water). It's always fascinating to see aquariums from decades gone by. Designs have radically changed over the years from both a material and aesthetic point of view.
Jellyfish culture systems. Medium pseduo-kreisals on right and large ones on left and straight ahead.
California Academy of Science worked with Tenji Aquarium Design+Build to build a total jellyfish system designed to culture jellyfish through every point of their life stage. The feat of engineering is impressive! Plus there is a nifty bonus seahorse culturing system.
Mollisquama parini is a supremely rare dwarf shark from very deep (300+ meters/1000 feet!) subtropical waters off both costs of the the Americas. Virtually nothing is known about these sharks.
We're ashamed to admit we don't give "Dutch" planted aquariums as much as press as "nature" aquariums, which rely heavily on rocks and driftwood (AKA hardscapes). However, aquariums like this remind us you can create immensely colorful, layered, textured aquascapes by simply using plants.
titles this aquarium "Magicznej Krainy," which is Polish for "The Land of Magic" ... quite the appropo title. Unlike nature-style aquariums which feature rocks and driftwood throughout the design, Dutch-style aquariums rely on the plants themselves to create the aquascape. Thus the selection of plants is paramount. The tank contains the following plant species:
Ammania sp. ‘Bonsai’
Alternanthera renickii ‘Pink’
Alternanthera renickii 'Rosanervig'
Cryptocoryne wendtii ‘Mi Oya’
Echinodorus sp. Mini
Eustralis 'Stellata Grof'
Hemianthus callitrichoides ‘Cuba’
Ludwigia repens ‘Rubin’
Mech Weeping moss (Vesicularia ferriei)
Mech Phoenix moss (Fissidens fontanus)
Micranthemum ‘Monte Carlo’
Microsorum pteropus ‘Trident’
Rotala sp Vietnam
