Love in the octopus' garden

The love lives of octopuses are far more complex than anyone thought, a team at the University of California, Berkeley, reported on Monday.

Graduate student Christine Huffard snorkeled in the waters off Indonesia to watch Abdopus aculeatus, an octopus with a spiky tan body the size of a small orange and arms 20 to 25 cm long.
