Native faunaFelucian bird
An avian native to the planet of Felucia, this creature had a bulbous body and translucent, pale skin.
One of these avians took flight in front of Jedi Knight Aayla Secura during her reconnaissance en route to Niango. Secura was distracted by the movement, and was thus unable to defend herself when Commander Bly and his troops opened fire, cutting her down in accordance with Order 66.
Gelagrub
Gelagrubs, also known as Felucian ground beetles, were large insect-like creatures that lived on the planet Felucia. Their preferred habitat was among the planet's towering mushroom forests. The gelagrub had a wide mouth above which were two vertically in-line eyes, and two rows of stubby adhesive legs that enabled it to climb steep inclines.
They were docile and easily domesticated creatures whose larval forms were used as mounts by Gossam colonists. Clone troopers of the Grand Army of the Republic also used them during the Battle of Felucia in the Clone Wars.
Like the rest of Felucia's flora and fauna, the gelagrub evolved with its own unique adaptations to the intense ultraviolet rays of the planet's sun. The gelatinous larval form was, for example, one of many Felucian creatures with a shimmering, semi-transparent skin. It was able to metabolize UV-filtering chemicals from its lichen food source, and distribute them to subdermal ducts, affording the gelagrub's internal organs a natural sunscreen. This also meant these creatures were constantly eating.
When a gelagrub pupated from its larva-stage, the adult emerged as a hard-shelled ground creature, not unlike a giant beetle, with a mirrored carapace in the place of the larval translucent skin to reflect the worst of the sun's rays.
