Jellyfish invade Jacksonville Beach Sunday

Hundreds of jellyfish floated ashore along Jacksonville Beach Sunday

JACKSONVILLE BEACH, Fla. – If you were at Jacksonville Beach Sunday, you probably had to dodge hundreds of jellyfish.

Jellyfish usually wash ashore this time of year, according to News4Jax meteorologist Mark Collins.

Jacksonville Beach lifeguards said a huge amount of jellyfish has washed ashore with the swell from the waves.

Jellyfish are mostly made of water so they die quickly after washing ashore but they will sting but it is very mild.

If you find a jellyfish washed up on the beach then it is probably dead but be warned, they can still give you a sting if handled, so leave well alone. 

It's the tentacles that sting. Jellyfish sting their prey with them, releasing a venom that paralyzes their targets.

Jellyfish don't go after humans, but someone who swims up against or touches one — or even steps on a dead one — can be stung all the same. While jellyfish stings are painful, most are not emergencies.

Most jellyfish stings can be treated without seeking a doctor's help.

If you get stung, Mayo Clinic suggests you:

  • Carefully pluck visible tentacles with fine tweezers.
  • Soak the skin in hot water. Use water that's 110 to 113 F.  If a thermometer isn't available, test the water on an uninjured person's hand or elbow — it should feel hot, not scalding.
  • Keep the affected skin immersed or in a hot shower for 20 to 45 minutes
