Pentasalmundus

The pentasalmundus replaced its ancestor the salmundus in BioCat River. It uses a salt-based compound to build its cell walls in a three dimensional pentagon shape, allowing the cells to better fit together into colonies. However, the shape isn’t perfect, and although they do fit together, there are often gaps and misshapes involved. Like its ancestor, colony members that die fill up with waste from the other cells, although this process eventually poisons the colony as it grows, preventing wads of pentasalmundus from becoming very large. It lives mostly on the shores of the river but will recede as the river drys up during the dry season. Once dry they will stay in a dormant state until the water returns in the rainy season. The cells can adsorb nutrients from the surrounding water and break down dead organic matter. They can grow up to 20 nanometers in size.
