Sneezing
Sponges
This is a
photo from a video of a sponge sneezing.
The reason this is so
astounding is because sponges don't have brains!
Both humans and sponges have
hairlike structures called Cilia that give them the
ability to sneeze.
As the sponge filters water
and
takes the nutrients out, they start to build up
waste minerals like sand and salt.
After this builds up, the
sponge then expands and contracts, and "sneezes" the
particles out.
The pressure a
sponge undergoes during it's
hours long sneeze phase is tremendously larger than
the pressure that a human
diaphragm experiences in our
millisecond sneeze phase.
