On the beaches of Texas, there’s been a troubling rise in sightings of a particular invasive jellyfish washing up on the sand.
What’s Going On?
Visitors to Texas shores are noticing a growing number of these jellyfish, as reported by My San Antonio.
The jellyfish in question, known as the Australian white-spotted jellyfish, sport a large, bell-like body sprinkled with tiny white spots and have feathery appendages. They can grow quite big, with an average diameter reaching about 20 inches.
Originally from Australia and its surrounding waters, these jellyfish likely made their journey here in the ballast water of ships.
Ballast water is collected by ships to ensure stability. This water, taken from oceans or docking areas, often carries all sorts of microscopic life, including bacteria and eggs.
Why Is This a Concern?
Invasive species are problematic because they can disrupt local ecosystems. They often outcompete native species for resources, leading to a decrease in biodiversity.
Besides loss of habitat, invasive species are a major contributor to species extinction. This jellyfish, in particular, poses a threat to marine life that feeds on plankton, such as shrimp, by increasing competition for food.
The good news is that while the white-spotted jellyfish’s venom isn’t lethal, they have a big appetite and can drastically impact populations of local zooplankton.
What’s Being Done?
Getting rid of these jellyfish won’t be easy, but it’s essential. Since invasive species multiply rapidly, it’s crucial to act quickly. Researchers are currently tracking where the jellyfish are landing to monitor their spread.
The best strategy is prevention to stop them from overrunning new areas. For shipping companies, this could mean better management of ballast water, specifically flushing it in the open ocean, away from the coast. Prevention is key!
