The majority of non-Terran sophonts in the known galaxy seem to have been wiped out by the Destroyers or natural disasters, parahumanity’s survival appears to have been a fluke. However, a few sophonts that have not yet developed the radio signals that draw unwanted attention have been discovered by Federation survey teams.
Cephalogongs: An aquatic species named for their superficial resemblance to a wobbegong carpet shark, except with a larger brain and tentacles unfolding from inside its’ mouth. Cephalogong society tends to be less “tribal” than “a bunch of individuals living in close proximity.” When cephalogongs find a spot on the seabed where they can build a fortified residence safe from predators, others tend to follow. Outside of mating season, neighboring cephalogongs tend to only interact under one of two circumstances, a sort of posse that forms ad-hoc to drive off an obnoxious individual, and the construction of fish traps. The traps are constructs of stone and shells that help to corral schools of fish-analogs towards a point where the builders lie waiting. Builders place their pheromone markers on the stones they handle, and will chase off any “freeloaders” who try to use the trap without contributing a stone. Aside from pheromones they also communicate via electrical pulses similar to nerve impulses, some parahumans and neoctopi have compared it to telepathy. Unfortunately it is most useful for indicating directions and actions, not so useful for communicating philosophical concepts.
The Pack Mothers: A plains-dwelling species with a life-cycle unique among the known sophont species. They have long, hexapedal fur-covered bodies with a narrow muzzle topped with three eyes and four large ears. They can rear up on their rear pairs of limbs to spot prey or predators. For the first 14 local years of their life they are raised by their mothers in a community of other mature females, but upon reaching maturity all become functionally male and leave their maternal tribe to hunt in the wilderness. Some males attempt to survive on their own, but the majority join loose packs that cooperate the bring down larger prey. Roughly once a year the males seek out female communities to mate with, typically offering large kills or rare fruits as incentive. If a male survives ten years in the wilderness they undergo a hormonal and glandular shift to produce ova rather than sperm and seek to join a female tribe. Few females rejoin the same tribe they were born to, but maternal instincts are sufficiently strong to compel mothers to care for any juveniles of their species and a tribe will rarely turn away a mature female if they have room, especially one already impregnated by her former pack.
Geror: Initially, this planet seemed devoid of intelligent life, with no visible structures or tool-using species. However, shortly after landing the survey team found themselves under assault by a veritable army of animals of assorted species. Mercenaries were quickly brought in to defend subsequent landings, but the strange hordes kept coming and worse, seemed to adapt to their strategies. The first hints of the cause for all that strangeness came with the distant observation of a tree-analogue producing some of the more aggressive “fauna” by budding. A dissection of one of those tree-analogues exposed massive nerve bundles with entangled with those of neighbors through roots and that the “trees” exuded pheromones based on their neurotransmitters that could direct the mobile creatures. It seemed that they were fighting a forest-sized brain that directed its’ troops with smelled thoughts.
Working theory on Geror is that the species of the planet evolved advanced scent-based communication to warn of natural disasters produced by multi-moon tides and wandering asteroids earlier in the star system’s history. As most species had mobile and sessile phases this allowed sessile parents to remotely direct mobile offspring and have them settle close enough for their nerve cords to entangle. Species that could smell the same pheromones had an advantage over those “out of the loop.”
It is uncertain how far the forest-brains extend or if the whole planet is one vast mind. More than one Noospherist sect has adapted it as their patron, though its’ biochemistry remains incompatible with Terran life and they have yet to enable communication with Geror.
