Did someone say resting fish face?

The #LonghornCowfish is easy to spot with its bright yellow color and the signature horns jutting from its head. But those horns arenโ€™t just for style โ€” scientists think they evolved to make this little cowfish a mouthful most predators canโ€™t swallow.

A three panel comic. In panel 1, two people are facing each other. The first person asks "Hey, do you want to drive really far and spend hours staring at distant, rapidly moving gray-brown objects while trying to find subtle differences between them?" and the second says "No." In panel 2, the first person says "What if they're bird-shaped?" and the second person says "Then absolutely, yes." In panel 3, the two people are standing and looking through binoculars at distant shorebirds on a beach. The first person says "Yay shorebirds season!" and the second says "Woo!"

Idea of Coral Reefs as Oases in Marine Deserts May Be Mistaken New research from Simon Brandl at The University of Texas at Austin challenges a long-held belief about coral reefs.

New research challenges the long-held belief that coral reefs are โ€œoasesโ€ in marine deserts. While among the worldโ€™s most productive ecosystems, their existence in nutrient-deprived oceans is the exception rather than the rule. @gobyone.bsky.social @utmsi.bsky.social

New research challenges long-held belief of coral reefs as oases in marine deserts The popular notion that coral reefs are often surrounded by "deserts", devoid of nutrients and plankton, isn't true.

A detailed summary of our paper's results is provided below. This work was funded by a Branco Weiss Fellowship and the US National Science Foundation.

Scientific semantics aside, why does this matter? It matters because reefs clearly depend much more on their surrounding oceans than commonly assumed. As we alter not just reefs themselves, but also broader dynamics like nutrients, currents, and plankton blooms, reefs will have to cope with both.

Not really, because the oceans around reefs aren't deserts. Most reefs do not occur in conditions we would define as nutrient-poor. They thrive instead across a vast spectrum of oceanographic regimes, and 80% of reefs are surrounded by waters we would generally classify as meso- or eutrophic.

Does that mean it's all wrong? Not quite, because coral reefs are indeed ridiculously productive. We compared net primary production across Earth's ecosystems and found that reefs outpace almost all other systems in their ability to produce biomass. They're absolute powerhouses. Dare I say, oases?

First, Darwin never said nothing about reef productivity & nutrients. In fact, old Chucky D didn't have the basic oceanographic knowledge to arrive at the paradox conclusion. Instead, it arose after the first coral reef ecosystem metabolism studies in the 1950s and was misattributed in the 80s/90s

Heard of "Darwin's paradox"? It refers to Charles Darwin's observation that coral reefs are wildly productive despite occurring in nutrient-poor tropical oceans. Reefs are, so the story goes, oases in marine deserts ๐Ÿ๏ธ...

Turns out that 2/3 of these assertions are very wrong...

When thinking of the 'model' planktivore on reefs, fusiliers come to mind - their fusiform bodies, forked caudal fins, and large eyes appear built for the job. But are these traits common among most plankton-feeding reef fishes? ๐ŸŸ
