These things can flatten themselves out, are uncomfortable without water, have a black head and and black tail and have a general sandy colour.

Do they look like these? http://flatworm.csl.gov.uk/gallery.htm
If so, the folk on that site (Central Science Laboratories) will be interested to hear from you. The pictures are of New Zealand flatwoms, a new(ish) invader to the UK. They're trying to keep track of their spread.

Hi,
It could be the Australian or New Zealand Flatworm, but description sounds wrong, and flatworms generally are monotone with a couple of exceptions.
If you look closely with a magnifying glass see if you can make out segments (lines running over the body). If it has segments it is one of the annelida members (worms, leeches.)
However a huge variety of worms and worm like species occur in water, and you don't say how big they are or how long the pit has been filled with water.
Two things come to mind.
1 A leech. Not all leeches have readily seen suckers and they move well in water and can flatten themselves out etc. Completely harmless and beneficial to nature.
2. If they are quite small they could be fly larvae such is midges. Many aquatic fly larvae have a worm like appearance.
Hope this helps.

It could be a worm of the species "planaria"; they're regularly brownish with a black head or tail, check the source for a photo:

Just build a sandbox and put the type of sand you want into it. Advice from one who has done it would be that you have to have some sort of cover to keep the cats out or your child will be playing in cat poopy.

Yep, flatworms...but if u are not so sure, get guide books on worms, insects and creepy crawlies, available in many bookstores. You can also take the chance to surf the web, type in the keyword, 'worms'

Sounds rather like a leech to me, they tend to swim in an exaggerated looping motion.

Sounds like a flatworm of which there are many different types. Does it look like this?

Wish you had put your country as they could be anything.
