The blobfish grows to about 12 inches long, and is found in the waters of south eastern Australia up to depths of 800 metres. They are inedible, but are often dragged up alongside other more palatable ocean dwelling creatures, such as crabs and lobsters. Because of this, their numbers are declining fast.
The flesh of the blobfish is only slightly less dense than water, meaning that it floats above the sea floor without needing to spend energy on swimming. It has relatively little muscle and spends its time bobbing along the sea floor swallowing whatever happens to float in front of it.
