Hello everyone, it is another bloody cold day here, no rain or wind just cold and yes I have the heater going.
This Tuesday I am going to tell you a little about a pretty indestructible creature and the creature is the Barnacle which I am pretty sure everyone has heard of.
Barnacles are the whitish hard, pointy lumps that you find encrusted all over seaside rocks, piers and underside of boats. They are related to crabs and lobsters but live in an almost indestructible shell that's glues to a hard surface.
When underwater they open two door like things in its shell to reach out with its feathery feet to catch passing plankton and food scraps. When the tide is out or they feel threatened the close the doors and hide inside.
They are so rock hard you might think they are part of the rock they are attached to, the glue they use to stick to stuff is so strong that scientists are trying to copy the make up or recipe to make a new water resistant adhesive.
