Surge of Pink Mean Jellyfish on Texas Coast
An unusual increase in sightings of “pink mean” jellyfish, which can weigh up to 50 pounds and have tentacles extending as long as 70 feet, has been reported along the Texas coast.
From Port Aransas to Corpus Christi, marine scientist Jace Tunnel, from the Harte Institute at Texas A&M University, noted that this year’s jellyfish presence is remarkable compared to what he has observed over eight years of research.
“I’ve never seen so many pink mean jellyfish before,” Tunnel remarked, adding, “I grew up on the beach and never encountered them this year.”
This species, a relatively recent discovery in Gulf waters, was first reported in the early 2000s. Initially, it was confused with the lion’s mane jellyfish.
In 2011, genetic testing confirmed it as a distinct species. “They’re called ‘mean’ because they feed on other jellyfish, like moon jellyfish,” Tunnel explained.
As the Gulf Coast currently experiences a bloom of moon jellyfish—its primary food source—reports of pink mean jellyfish sightings have surged.
“We’re seeing a bloom now with the moon jellyfish, which is why we’re getting so many sightings of these pink ones,” Tunnel pointed out.
While stings from pink jellyfish aren’t usually life-threatening, they can cause discomfort. Tunnel advised that if stung, it’s important to get out of the water and carefully remove any tentacles. Rinsing the area with seawater is recommended.
He mentioned that soaking the affected area in warm water for about 20 minutes can help relieve pain. He also suggested that vinegar might effectively neutralize the stinging cells.
As cooler temperatures arrive, both the moon jellyfish and the pink mean jellyfish are expected to eventually retreat from Texas beaches.
