Sponges ‘sneeze’ to dispose of waste

Sneezing out mucus may be one of the oldest ways for organisms to get rid of unwanted waste.

Additionally, authors find that other animals who live with the sponges use their mucus as food.Sneezing out mucus may be one of the oldest ways for organisms to get rid of unwanted waste.
