Ioprey are a species of Raptorial Bird Wyvern, characterized by their red-orange hide and rounded head crest. Hunters familiar with Ioprey have observed that their permeable skin constantly need moisture. For this reason, Ioprey tend to dwell in danker regions - such as the Swamp,Great Forest and Jungle - where they can easily avoid dehydration. However, Ioprey are still found in places outside these comfortable habitats, such as in the Volcano and even the drier Fortress.
The Ioprey appears very closely like a typical small herrerasaurus. It is notably lust red in the skin, with some black markings while purplish lavender by the limbs.
Ioprey's head shape arcs on the back part, while the snout looks like a very large beak. It's eyes are practically yellow-amber and has no visible pupils.
Ioprey are easily distinguishable from other Raptor species thanks to their larger size and bulbous frog-like throat sac. This enlarged throat houses the Ioprey's potent poison sac, which gives it the ability to spit poison at its foes. Whilst this might be a small nuisance to experienced hunters, the fact Ioprey hunt in packs can quickly make them a dangerous threat to a hunter not carrying a supply of Antidotes. The duration and toxicity of the poison varies between Ioprey found at different Ranks. Those found in G-Rank will last much longer and be far more punishing than those of Low or High Rank.
Like all Raptor species, if killed mid-jump, an Ioprey is likely to divide into multiple pieces, leaving nothing behind for the hunter to carve from. Similar to its cousins, an alpha Ioprey, known as an Iodrome, controls a pack.
