A big increase in reports of Asian tiger shrimp along the U.S. Southeast coast and in the Gulf of Mexico has federal biologists worried the species is encroaching on native species’ territory.
The shrimp are known to eat their smaller cousins, and sightings of the massive crustaceans have gone up tenfold in the last year, biologists say.
The black-and-white-striped shrimp can grow 13 inches long and weigh a quarter-pound, compared to eight inches and a bit over an ounce for domestic white, brown and pink shrimp.
Scientists fear the tigers will bring disease and competition for native shrimp. Both, however, can be eaten by humans.
