Parasitic Flatworm Could Decimate Coral Reefs Worldwide
A coral-eating flatworm with a unique camouflaging strategy could be a major threat to the world's coral reefs, according to researchers in the U.K. The parasite, called Amakusaplana acroporae, infects a type of staghorn coral known as acropora, a major component of reefs, and can destroy its coral host very quickly.
The parasite has been detected at the Great Barrier Reef, and because it has no known natural predators, researchers are concerned it could spread quickly and decimate reefs worldwide. A novel camouflaging strategy makes the flatworm difficult to detect and monitor, the researchers say.
When eating the coral tissue, the worm also ingests the coral's symbiotic algae. Instead of digesting the algae completely, the worm keeps a fraction of them alive and distributes them, along with the fluorescent pigments that give coral its characteristic hue, throughout its gut so that it perfectly mimics the appearance of the coral.
The parasite has been identified in numerous aquarium-based corals, and biologists worry that it could spread rapidly if aquarium-raised coral, fish or seaweed are introduced to natural reef environments.

In a historic move, the Delaware River Basin Commission (DRBC) voted Thursday to ban hydraulic fracking in the region. The ban was supported by all four basin states — New Jersey, Delaware, Pennsylvania and New York — putting a permanent end to hydraulic fracking for natural gas along the 13,539-square-mile basin, The Philadelphia Inquirer reported.

Colombia is one of the world's largest producers of coffee, and yet also one of the most economically disadvantaged. According to research by the national statistic center DANE, 35% of the population in Columbia lives in monetary poverty, compared to an estimated 11% in the U.S., according to census data. This has led to a housing insecurity issue throughout the country, one which construction company Woodpecker is working hard to solve.
