A family who were trying to enjoy a spring barbecue were shocked to find they had been surrounded by a group of robber crabs.
The giant crustaceans, also known as coconut crabs, measure up to metre in length and have a strong sense of smell.
When an unwitting family decided on some al fresco dining on Christmas Island the crabs came running.
Photographs of the barbecue show more than 20 of the coconut crabs eagerly awaiting a chance to snack on some leftovers
A little girl looked unfazed as the enormous crabs surrounded her as she ate her dinner in a fold-up chair

WHAT ARE ROBBER CRABS
Robber crabs are the largest land crustacean in the world and many call Christmas Island home.
They can weigh up to four kilograms and measure a metre wide.
Some can live up to 50 years of age.
Robber crabs forage floor for things such as seeds and fruits.
However they also scavenge dead animal carcasses for food – including eating other crabs.
Coconut crabs are exceptional climbers and move fast when it comes to food.
It’s name comes from its tendency to take foreign objects and run off with them.
Robber crabs are closely related to hermit crabs and use seashells or coconuts for protection until they develop a hard abdomen.
Drivers on Christmas Island are asked to ‘slow down and drive around’ the animals as if their hit by a car they could be killed.
