"A monstrous bloom of toxic algae looming across the Texas coast has shut down oyster season. Fueled by Texas' ongoing drought, the algae — known as Karenia brevis— thrives in warm, salty water and has spread through the bays and islands along Texas' 350-mile coast, says Meridith Byrd, a marine biologist for the Texas Parks and Wildlife Department. The algae could cause nausea, vomiting and diarrhea in humans and is harmful to fish but not fatal to people, she says."
