Sentinel Crab

It's the perfect guard dog...

Powerful armour plating. Two great, big claws. And eyes on stalks!

Always watching...
I found two crabs commonly called the Sentinel.

One is a genus known as Macrophthalmus, found on muddy shores in the Indo-Pacific much like their Fiddler Crab and Ghost Crab relatives.

The other is Podophthalmus vigil, who's range extends from Japan and Australia all the way out to Samoa and Hawaii. They belong to a family called Portunidae, the Swimming Crabs. With their hindmost legs flattened into paddles, this Sentinel can dart about in search of fish and shrimp to eat.

Or, of course, to nab that dastardly cat burglar by the ankle.

I thought it might be cool to have a new superhero called Sentinel Crab Man, but then I realised he would have to walk through doorways sideways. Like a crab!
