Clam eats salt:

Alan Henness

There are three fundamental questions for anyone advocating Brexit:

1. What, precisely, are the significant and tangible benefits of leaving the EU?
2. What damage to the UK and its citizens is an acceptable price to pay for those benefits?
3. Which ruling of the ECJ is most persuasive of the need to leave its jurisdiction?

I reckon the clam is trying to move. I know some do this by flipping themselves using their "foot" (not their tongue, they are filter feeders). It can't get a grip on the smooth table top so tries further out.

Hmm. I sometimes use salt crystals to exterminate the molluscs (gastropod, not bivalve) that invade the house through the air-vents.

I wonder what happens to her organism after having absorbed raw-dry salt? Will it survive?

From the drips I am guessing that it might be causing the clam to loose water - not a good idea for an aquatic animal on dry land.

Actually the makers of the film should probably be reported to the nearest animal protection agency for causing unnecessary suffering!

Great! Bit like the honey-pot ants where some members have distended abdomens and act as living storage vessels. They can be the size of small grapes.

Find that cruel. Is that an irrational feeling to have?

I do not think so, perhaps even individual ants have a right to existence. So why do I feel a bit uneasy about "popping" a honey-pot ant in my mouth yet will poison hundreds to prevent them invading my house?

One is immediate/personal the other deferred/remote, the difference between shooting a person face to face and launching a missile at them - is that the only difference?

(Actually I do feel a small twinge of remorse about applying the poison, but only a very small one!)

Wow! Didn't know that many had been found, and especially not the very small ones. Though, a little bell reminds me of something half heard on the radio about "possible Earth-like exo-planets". Might have been those infinite monkeys.

I preferred this one. Just built a variable mark-space circuit (to vary the brightness of an LED) using a 555 timer. Wonder what sort of results I would have got with a 666 timer? Variable demon-imp ratio?

Oops, nothing to do with the natural world . . .
