I headed off to the fank but I must have turned left instead of right, because I had a very nice week in Essex. There were people down there mowing their lawns! Even if the hens weren’t scratching my grass to bits there wouldn’t be enough to mow yet! Most weather-related talk was hosepipe bans and how to manage if water has to be collected from a standpipe. If only I could post my puddles south. Interestingly, lots of pubs had signs outside saying they were smoke-free!
Back at the pier the ‘Polestar’ was in doing something to the green buoy. I suppose the batteries for the flashing light have to be checked. They must have a very powerful crane as the buoy is supposed to be firmly fixed to the sea-bed.
The airport has started. Lots of diggers and stuff came in on Monday. Rumours flew round the workers were all Polish but actually I think they come from the wilds of Dalmally. They are keen to organise a summer six-a-side shinty league. JA was trying to sort out the rules, but apparently they use a ball, which rather confused us.
Work today is hampered by the discovery of a smoke bomb and the police have closed the road west of Friesland (luckily just beyond me, or I would have to have spent the afternoon in the pub with a new barrel of Pipers Gold) and are waiting for a helicopter to come in and blow it up. Not sure what will happen if the road isn’t open before the ferry gets in, as the other way round is only suitable for 4WDs.
Today’s question is about baby crabs. Do crabs lay eggs? Lobsters and prawns do, but I’ve never seen crabs with eggs. Does a baby crab have another name, like puppies and dogs, or are they just not cuddly enough? I need to explain this to a six year old, so not too technical please.

Yes Nic crabs do indeed lay eggs. It is difficult to see them when they do as crabs need to moult their shells to breed and so tend to go into hiding until their new shells harden. Also crabs tend to only carry their eggs around for a short period before casting them adrift into the currents where they hatch and the "baby crabs" live amongst the plankton for a while. During this time they look nothing like crabs but more like little barely visible prawns but with a couple of spines added to try to prevent them getting eaten. This stage of their live cycle does have a very technical name but larva will generally do. I don't know how long they spend drifting about, probably depends on the species of crab and the right tides to bring them back to shore, but eventually they will moult their shells and change into "proper" baby crabs to spend the rest of their lives amongst the rocks and seaweed.
