About the mon: Glowinia is a medium sized aquatic creature with long body, big fins, 3 gills in it's muzzle and X pairs of mushroom-shaped antennas, it doesn't have eyes, meaning it's blind, but it's blindness doesn't affect it, as it lives in cave and covered lakes, and deep waters.
It's small fins in its head permits Glowinia to localize preys and other creatures, it can shake its antennas to communicate with other Glowinias and express feelings, when it does this, the antennas also glow, helping attract any curious prey in the dark lakes.
Because of it's alien-like appearance many believes Glowinia is dangerous or poisonous, however it is extremely friendly!! It will only attack if attacked or threatened. It is very shy, making it difficult for Glowinia to be found, because of it's glowing antennas, when seen from outside the lake can look like a starry sky with sparking stars inside it.
Glowinia rarely befriends humans, but if it becomes your friend, it will be extremely loyal, becoming your most trustworthy and caring friend!

About the design: Glowinia body and head fins were inspired by an Olm, the body fins were inspired by Flying Fishes and it's tail fins and antennas were inspired by the tail and eyes of a prehistoric animal called Opabinia!

About the name: Glowinia name is a mix of the words "glow" and "opabinia", one of the 3 animals that inspired Glowinia
