Hermit Crab goes walk-abouts

One of the recent additions to our little marine aquarium was a hermit crab.  He turned up in a chocolate brown periwinkle shell.  A couple of days later he had upgraded to a dogwhelk shell.  

The other day I spotted him, out and about and very active – which is unusual.  I snapped some video in action and it was so fascinating that I just kept rolling.

The camera is a but shaky — couldn't be helped.  Focus isn't great — I just wish the camera could get closer.

Chancre Crab Eats Gooseneck Barnacle

Our Chancre Crab (aka. Brown Crab, Edible Crab, Pastie Crab) enjoyed a feast recently.  We had found a washed up fish-box that was covered in Gooseneck Barnacles.  I scraped a few off the plastic box and strung them up our little marine aquarium.  They were fascinating to watch — sieving the water for food then retracting into their shells to eat.  That was until Chancre got wise to them and decided to get piece of the action for himself — even moving rocks so he could reach them!
