Koi scale epidermis contains large intra‐epidermal bodies ( IEB s). IEB s are dynamic and circular structures that form in low frequency within the epidermis. During formation, an IEB pulls down the microridge‐laden surface layer, which takes on a creased or wrinkled appearance. After the IEB constricts, the microridge layer unfolds to its original state. The newly described IEB s are distinctly different from the recently reported apical rings which are situated on the surface of individual epidermal cells. While apical rings are directly exposed to the external environment where sampling can occur, IEB s appear to reflect intra‐epidermal events such as sequestering of dead cell remnants.
