The Carpoopt is, obviously enough, a genus of carpeting algae descended from some Poostalk populations in the waterways of Kamm. With increased access to nutrients and little competition, these flora are fine-tuned for exploiting as much of their environment’s resources as possible.

A Carpoopt thallus is fine and tenuous, and with a level of cell derivation similar to the Poostalk species of which it derived from. You can always expect to find Carpoopts growing like their namesake, with each individual thallus being closely-linked clones of the other. With a consistent enough supply of nutrients, Carpoopt patches can extend quite an area, and as clones are connected via a network of fine, rhizoid-like holdfasts, sugars and the aforementioned nutrients are easily shared. Because of their simple structure, these algae can regenerate quickly after disturbances, and severed thalli could even grow into carpets of their own should they deposit in a suitable location.

There are many dozens of Carpoopt species, and it is often difficult to discern one from the other; environmental trends however, are easier to note. Species found in the Kamm Tundra sport a much darker color than their northern cousins in order to better gain heat, and can go dormant in especially brutal winters. Some species prefer consistently intense light to best grow, while others can fare well in low light. Most species prefer a consistent flow of oxygenated water, and while a few hardy species like B. cowpattii can be found growing in standing water, they face considerable competition from their Poostalk forebears there.
