On sandy beaches the substrate is often
so soft that it is easy to dig in. Many organisms
do it and spend a great deal of their lives dug down into the substrate.
You may already have an idea that there are organisms down there because
you have seen their piles
of excrement, holes
and siphons.
Simple tools
To be able to do the things that have already been described no equipment
is required, but if you get a pen and paper you can note
everything you have seen, even draw. Photo and video cameras
are also very usefull and very valuable in connection to your research.
It is important that you document your discoveries and with a pocket
lens you can see fantastic things. A pocket lens helps you study small
things and see all the detail. A pair of tweezers makes it easier
to handle small objects.
To make it easier to catch organisms in the water or on the
bottom, a net is recommended. There are cheaps nets that can be
bought in most stores, but it probably will not last very long if it is
dragged along the bottom. In the long run it can be cheaper if you buy
a more expensive model with a more sturdy frame and the net bottom comprising
a metal mesh. A cheap net can nevertheless last a long time if you take
care of it. When you want to catch something that is on the bottom, a
spade and a sieve maybe more suitable.
If you want to take your catch home or to school, you will
probably need plastic bags, jars, buckets and bowels.
Transparent bags and jars are usually the best because you are able to
see the contents. To make it easier to see both light and dark objects,
a good idea is to have both black and white bowels with you to the beach.
