Arktanises utilize a cerebral ganglion, allowing their mouth and eye to be in different segments of the body without extending neural message speed. This allows them to keep a look out while foraging for food. They are hexapods - they possess eight limbs, with six of them adapted into legs with minor-webbed feet for minimal aid in their movement through their wetland environments (both to soften how far they will sink into the substrate as well as to allow for some swimming should the land suddenly drop off and leave them floating). Because their ears are located near their head, which is often plunged under the water's surface to forage for food, their ears never evolved to be more than tympanic membranes, with no access to the inner quadrants of the body.
