Increasing blanket of mucus-like substance in water threatens coral and fishing industry

Thousands of euphausiid shrimp, the species identified here in Resurrection Bay as Thysanoessa spinifera. were washed into the intertidal zone and on the beach near Whittier

Last week, Alaska became one of at least 32 states to report finding zebra mussels in a product called moss balls which were sold at local pet stores.

A new study found that multiple species of bacteria deplete oxygen from the water effectively suffocating sea stars. These microbes thrive when there are high levels of organic matter in warm water and create the low oxygen conditions.

A harmful algal bloom, better known as a red tide, has been building up at Elands Bay on the West Coast, about 220km north of Cape Town.
