Researchers go underwater to study how sponge species vanished: Research suggests that sharp rise in water temperatures led to death and disappearance of some species from the shallow water of Israeli shores

  • The researchers believe that the main reason for the disappearance of the sponges was the rise in seawater temperatures during the summer months.
  • The researchers collected 20 specimens of the Agelas oroides sponge, 14 of which were transferred to shallow waters at a depth of 10 meters (about 30 feet), at a site where the sponge was commonly found in the 1960s.
  • At a temperature of 28°C (82°F), most of them stopped pumping water, and during the month of July, when the water temperature exceeded 29°C (84°F), all of the sponges that had been transferred to the shallow water died within a short period of time.
