The Padre Island National Seashore says it recently received a “not-so-welcome visitor.”
Because of their size, they can clog nets, negatively impacting the shrimping and fishing industries.
“In the Gulf, this invader has formed huge swarms in recent years. Each jellyfish can clear 50 cubic meters of water filled with plankton in one day, making dense aggregations of Australian spotted jellyfish dangerous because they can alter food webs in the water column.” the Texas Invasive Species Institute states.
The species was first spotted in the U.S. in 1981 in California, and it was first seen in Texas in 2006 in Galveston, according to the“The polyp stage of this species, which buds off to develop juvenile jellyfish, could be transported to our region on ship hulls. With this jellyfish being found in California waters over to the Gulf of Mexico and Atlantic waters it is a threat to Texas’ coastal ecosystems,” the Texas Invasive Species Institute states.
