Shinouta is large, rivaling the size of Akantor and Ukanlos with large, jagged purple wings that helps it fly through the sky silently. The body is rather colorful with a solid bright yellow throughout the body while the head is a darker shade of yellow with orange fin-like extensions from the cheeks. The tail is long and whip-like and is also yellow and the very tip of the tail is aquamarine.
When threatened by a hunter or monster, they are vicious fighters, shooting globs of poison, roars that can cause sleep and or confusion, and emitting gases that causes confusion.
Shinouta are high on the food chain where ever they are and eats mostly the resident Flying and Bird wyverns in the particular area. These wyverns are Yian-Kut-Ku, Yian Garuga, Seregios, Malfestio, Great Maccao, Rathian, Rathalos, Great Jaggi, Tigrex, Brute Tigrex, and even the DreadKing Rathalos can fall prey to Shinouta. Despite its uncanny diet for wyverns, there are at least three different wyverns that Shinouta has to deal with. One of these wyverns is Espinas, the thorn wyvern whose strength rivals that of shinouta. The second wyvern is Meraginasu, whom Shinouta is terrified of. And the third wyvern is unconfirmed but it is on equal footing with Shinouta, this wyvern creates sound waves that are strong enough to destroy boulders.The search for that wyvern still continues.
