The Alien sophonts #1

So, these guys are 5 of the 8 living alien civilizations that I've created so far, the other 3 being the Frhnnnqu, which I've shown and 2 other races, which I will hopefully show in the near future.

Clockwise:

1. The Platosapiens, a name given to them by humans since Platosapiens don't communicate vocally, are a relatively new race of alien sophonts, living in a rocky superearth 3 times the size of our planet. Their current technological level is relatively primitive, being similar to that of the late 20th century humans, yet still maintaining connection with other far more advanced alien races, though not a strong one. They evolved from creatures rather similar to Earths' starfish, having a sevenfold radial symmetry (most starfish have a fivefold radial symmetry though) and being carbon-based, but they do have their differences, such as the possession of an elastic, but strong skeleton and a brain, in fact 8 of them. In each limb Platosapiens have a pair of eyes, which function as one. While the larger eye allows them to see, it is the smaller one that gives them color vision and depth perception. They also have large semi-retractable claws, used for digging in their ancestors and also a small tentacle in each limb used for holding food and small object as well as communication.

2. The chronoans have now been revised, but most of the info on them remains the same. They evolved from pack-hunting nomadic predators, which also used to have another pair of limbs, used solely for stabbing prey. That was over 100 mya though and they've since been lost. Unlike the previous version, they lack actual eyes, using instead advanced heat detectors. The 2 long tentacles are in fact part of its' tongue, which with the passing millenia turned into a better manipulator, with only a part of it remaining as an actual tongue.

3. Sophomedusa, that's the name humans have given them, since like the Platosapiens, the Sophomedusa don't communicate vocally, instead using electric signals, similarly to the elephant fish of Earth. They lack eyes, but instead use electroreceptors, similar to those of sharks or platypodes, but far more advanced. Unlike most of their homeworlds' creatures, their lineage is an ancient one, appearing around the same time as multicellular life appeared in their planet. Their most fascinating feature though, is their ability to regenerate, which has allowed some individuals to live for hundreds of thousands of years. They do so, by forming cocoons around themselves and then proceeding to slowly grow a new body, while their memories are slowly transferred to it. Regenerating takes a lot of energy though and thus before doing so, they need to eat a lot. They can also regenerate lost limbs under normal conditions. 

4. The sciihu remain some of the most peculiar sophonts, due to their biochemistry and general physic. They're ammonia-based, living in a planet similar to Earth, but with a few differences, such as the extremely low temperatures and the seas, which instead of being made of water, are made of liquid ammonia, covering the planet in vast dark red seas. Sciihus appeared around 11 mya and are part of a lineage of large elephantine "herbivores", originally being up to 7 m tall, but now growing no more than 3.5 m. They lack actual muscles, and instead use gelatinous, movable almost liquid masses. Their anatomy too is rather complicated and will be explained later in the near future.

5. These are the now revised Deluvians, differing in size and slightly in anatomy. They are now far more advanced technologically, being known for their extensive organic technology.
