It sounds like a spin-off from "
The Little Mermaid" or "
Spongebob Squarepants": An octopus builds a mobile home under the sea by heaping up coconut shells. It moves in ... and then it carries the whole heap across the seafloor. "
It was an extremely comical sight," said marine biologist Julian Finn, who spotted the behavior off the Indonesian coast. "I never laughed so hard underwater." Let's just hope those clever cephalopods don't develop opposable thumbs. That won't be such a laughing matter.
