The blue buttons don’t sting quite in the same way as jellyfish, but do have stinging cells that can cause skin irritation, Northup said. It’s best to avoid them if you see them on the beach.
But the blue button is not nearly as treacherous as the Portuguese man o’ War. Because they have a mild sting, blue buttons can irritate the skin but they’re not that dangerous to humans, Paul Bologna, an associate biology professor at Montclair State University in New Jersey, told the Asbury Park Press.
Are Porpita Porpita poisonous?
Porpita porpita stings usually do not hurt but can cause skin irritation. They have gaseous bodies which allow them to float on the surface and are propelled by wind and ocean currents. There are actual jellyfish and other types of marine life in the archives.
What does the blue button jellyfish eat?

What does the Porpita Porpita eat?
Unlike Velella, which prefers a passive diet, Porpita will hunt active crustaceans like crab and fish. It competes with other drifters for food and mainly feeds on copepods and crustacean larvae.
Are blue jellyfish poisonous?

Porpita porpita. Porpita porpita, or blue button, is a marine organism consisting of a colony of hydroids found in tropical and sub-tropical waters of the Pacific, Atlantic, and Indian oceans.
Where are the tentacles of the porpita located?
Tentacles are only found on the dactylozooids, which exist furthest away from the mouth, towards the outer part of the hydroid colony. The blue button is a part of the neustonic food web, which covers the organisms that inhabit the region on or near the surface of the ocean.
What happens when two Porpita porpitas are separated?
When two pairs of Porpita porpita and Caranx malabaricus are separated by species, then returned to the same tank, the juvenile fish will return to their respective partners, even when forcibly separated from it. The blue button sting is not powerful but may cause slight irritation to human skin.
Who was the first person to identify Porpita?
It was first identified by Carl Linnaeus in 1758, under the basionym Medusa porpita. In addition, it is one of the two genera under the suborder Chondrophora, which is a group of cnidarians that also includes Velella. The chondrophores are similar to the better-known siphonophores, which includes the Portuguese man o’ war, or Physalia physalis.
