This is the beginning of the animals, although you would be hard put to realise it. At present you are an amorphous blob of cells, with digestive capabilities spread over the external surfaces. You survive mostly in sea water, where sufficient nutrients pass by you that you can live.

You are, oddly enough, rather like a giant, multicellular bacterium. It’s odd how certain approaches to life appear again and again, at different scales and with different mechanisms, but the same behaviours.

And like all forms of life, if you don’t find a niche that no-one else can use and occupy it, you will be squeezed out by other forms which do. You need to improve your ability to take in nutrients.

So far, the best strategy has been bigger and bigger balls of cells, but that is reaching its limits as you just can’t pass enough chemicals from cell to cell.

You may be able to increase your surface area, by letting the water flow right through you, in holes in the clump. Then no particular cell will be too far from the energy source.

This will make it harder for cells to specialise though. Each cell will be very similar to the others.

It might be better to stick in a solid mass, and find another way to gain advantage.
