Excuse me, dear, which octopus are you?
By Susan Milius
Male blue-ringed octopuses seem to get pretty far along in courtship before they know for sure whether they’ve found a genuine female, report California researchers.
Males reached out and touched another male as readily as a female, say Mary W. Cheng and Roy L. Caldwell of the University of California, Berkeley. In the July Animal Behaviour, the researchers discuss 15 close encounters between male octopuses and 9 between a male and a female.
Watching the Australian species Hapalochlaena lunulata in a lab revealed no apparent differences between male octopuses approaching another male and those flirting with a female.
