An underwater photographer has captured rare footage of a vibrant venomous Fire Urchin.
The multi-coloured creature has been filmed moving along the sea bed in the Lembeh Strait, Indonesia.
The colourful rainbow critter, known as a Fire Urchin, was spotted by Melissa Yeo from Brisbane, Australia during a dive.
Remarkably the detailed footage even shows other fish and shrimp hidden in the spikes of the urchin.
The tiny creatures use the urchin as protection from larger predators – even though the Fire Urchin is venomous itself.
Melissa, 41, said she had received lots of great reaction from people watching the video.
She said: “These colourful Urchins actually glow and look so amazing as they crawl along the sea bed in clusters.
“These fire urchins are quite interesting as they can be solitary but often observed to cluster together, moving along the sea bed.
“What is interesting is to observe the smaller critters such as small fish, like the cardinal fish and other critters like shrimps that lives among and uses the spikes of the urchin as protection from other larger predators.”
