Foot-Long Invasive Shrimp Confirmed Off TX Coast; Carries 17 Viruses Dangerous To Native Species [View all]

A truly jumbo shrimp is causing big worries about the future of the Gulf of Mexico's ecosystem. The Asian tiger prawn, a foot-long crustacean with a voracious appetite and a proclivity for disease, has invaded the northern Gulf, threatening prized native species, from crabs and oysters to smaller brown and white shrimp.

Though no one is sure what the ecological impact will be, scientists fear a tiger prawn takeover could knock nature's balance out of whack and turn a healthy, diverse marine habitat into one dominated by a single invasive species.

"It has the potential to be real ugly," said Leslie Hartman, Matagorda Bay ecoystem leader for the Texas Parks and Wildlife Department. "But we just do not know."

The tiger prawns from the western Pacific - which can grow up to 13 inches long - have been spreading along the Gulf Coast since 2006, but their numbers took off this year. Shrimpers pulled one from Texas waters for the first time in June.
