Eleven Armed Sea Star.
Before you start counting, these guys can have anywhere between 7 - 14 arms.
They are amongst the oldest living creatures on the planet.
They have the ability to multiply by simply pulling their own arms off. The amazing thing here is that while the new single arm grows a whole new starfish, the original star fish just re-grows another arm in its place. Now this has to be a step up on the phrase breeding like 🐇 🐇 surely?
It moved very quickly actually within 2 minutes it had traversed across the 1m wide rock and slide away. Truly lucky to have this place as my backyard.
