World's biggest insect is so huge it eats carrots. Adventurer Mark Moffett has found the world's biggest insect - which is so huge it can eat carrots. Former park ranger Mark, 53, discovered the giant weta up a tree and his real life Bug's Bunny has now been declared the largest ever found.
The majority of the worldâs volcanoes are found deep underwater and now scientists have been able to record one of these eruptions as it happens to discover the sound it makes. The bubbling lava erupting from the volcanic vent Hades (above) produced a distinctive acoustic signature.
A second major site of active volcanism is along the axis of the oceanic ridge system, where the plates move apart on both sides of the ridge and magma wells up from the mantle, creating new ocean floor along the trailing edges of both plates. Virtually all of this volcanic activity occurs underwater.
