BABY CORALS AND FISH SMELL THEIR WAY TO TH BEST HOME
New research suggests that these creatures, baby fish and coral larvae, smell their way to neighborhoods where the living is good. Scents emitted by certain species of adult corals draw fish and coral larvae to healthy reefs, while the noxious odor of out-of-control seaweed drives them away from damaged ecosystems.
Young fish and coral larvae are cast out into the open ocean after they are born, to swim or float away on currents to new ecosystems. Some eventually return to their spawning grounds—especially if their hometown happens to be in a protected marine habitat—while others settle elsewhere. But these days, many fish and coral larvae are finding themselves with limited options: More and more unprotected reefs have been taken over by seaweed, which smothers coral, disrupts food webs, and perhaps even poisons potential settlers.
Both fish and coral larvae have been observed navigating away from those degraded reefs and toward healthy ecosystems. A baby coral is “a bag of snot with some cilia around it. How could it go one place and not another?”…… continue reading
Chain coral This hand sample is a really spectacular example of a fossil type known as a Chain Coral from the Silurian.
Each cell, or each link in this chain, was the home of a different individual organism or polyp. The proper name of this genus is Halcyites. They were generally small corals; this sample is only about 10 cm across. These lines evolved during the Ordovician and went extinct at the end of the Permian.
This sample was found at the Wrens Nest site, Dudley, West Midlands, UK. The location actually became Great Britain’s first National Nature Reserve site due in part to the quality of the fossils at that location. The sample is owned by the Black Country Museums.
A cool splash of color kicks off Color of the Week for our latest palette, Coral Cooldown. We love Behr in Wet Coral. The vibrant orange-red makes us think of snorkeling in the tropics, or selecting bright flowers from the market. Used as an accent, ceiling color or on all four walls, we hope you’re inspired by the images above..
