Macroamoeboids, Rhizopodus enigmaticus are highly intelligent but uncommunicative amoeboid aquatic lifeforms native to New Poseidon. A large specimen can reach a diameter of several meters, although most are smaller. The intelligence of the macroameboids was only discovered several decades after New Poseidon was settled, when ecologists observed how they employed some rather clever means of directing the leviathans. Transapient experts have studied these communications but no hyperturing or hyperbright translation has been intelligible to any being of SI:<1 intelligence. Macroamoeboids live in complex reef-like societies and they communicate with each other through elaborately integrated releases of motile aquatic pheromone-like cells.
