I try not to be prejudiced, but I'm afraid these give me the heebie jeebies.
What is it about tentacles that's so sinister? This can't be a merely personal terror: think of all those tentacles of terror we hear about, of all those chiefs of criminal organisations sending out their tentacles into the surrounding countryside.
Try using the word trunk, instead - the president sent his trunk over the border, searching for the enemy's weak points - it doesn't work, does it.
So, what is so sinister about tentacles? Well, apart from their habit of sliding out from narrow crevices to strangle people, tentacles can call on some pretty serious armoury. Some tentacles have suction discs, and some have hooks. Some tentacles have things like bottle caps on them that act as hole saws, some release sticky threads to capture their victims.
Right. So where are we to spot one (hopefully from a distance)? Octopodes are rare round here, but hydra are to be found in almost any pond (though they're usually only just big enough to see).
If you're near a beach then you might find a sea anemone.
However, the easiest tentacles to see are probably those on a slug or snail.
If you do spot a tentacle then don't forget that some of them can see, smell, and taste.
Yes. So do take care, now.
Spot the frippet: tentacle. This word comes from the Latin temptāre, to feel.
