Most dolphins are 'right-handed', say researchers
Bottlenose dolphins found to have an even stronger right-side bias than humans

Dolphins, like humans, have a dominant right-hand side, according to research.

About 90% of humans are right-handed but we are not the only animals that show such preferences: gorillas tend to be right-handed, kangaroos are generally southpaws, and even cats have preferences for a particular side – although which is favoured appears to depend on their sex.

Now researchers have found common bottlenose dolphins appear to have an even stronger right-side bias than humans.

“I didn’t expect to find it in that particular behaviour, and I didn’t expect to find such a strong example,” said Dr Daisy Kaplan, co-author of the study from the Dolphin Communication Project, a non-profit organisation in the US.

1. So Dolphins have hands?

I thought they only had fins.

2. Life on Earth shares fundamental DNA

How curious that there's a right-handed bias that crosses our Earthly species!

Thanks, Judy Lynn. Have a happy Thanksgiving!

3. First time I've heard of this, had no idea.

Have an excellent day, PJMck.

Thank you!
