Young spittlebugs feed by sucking juice from plants. Some of this juice passes through their bodies and oozes as bubbles from openings on their bodies. The bubbles don't burst easily, so they quickly pile up. Sometimes these young spittlebugs are completely covered with bubbles.
Giant sea sponges found off BC coast
Giant sea sponges found off BC coast The colony of giant sea sponges living near the
Queen Charlotte Islands is the only place in the world where the
sponges still live in massive groups the way they did 65 million
years ago. The four colonies found spread over 1000 square
kilometers. Full grown sponges grow up to two metres high and three
meters long and can live to be 200 years old. Although these
sponges are huge, they are very delicate because their skeletons
are made of silica. Scientists have found huge fossilized sponge
reefs all over the world, but this is the first living one found.
The colonies are 250 meters below the surface, so they have not
been discovered before now, and have to be explored with a
submarine. Scientists understand very little about sponge reefs and
are concerned that bottom fishing could damage the
colonies. MARCH 9, 2001
