The beautiful, but venomous, Lionfish :

 I’ve been away down at Khao Lak, near Phuket, for a week and took a live-aboard snorkelling trip out to the Similan Islands for 3 days/2 nights. Still have lots of photos to sort through, but just a couple for you now 🙂

A colony of lionfish, 6 altogether. With a poisonous sting in their spines you have to be careful !
