Creature reference sheet for a 3D animated children's science film, soft stylized 3D render, dark teal twilight-zone water background like image 4, no text and no labels. LEFT HALF: the silver hatchetfish, anatomy exactly like the real fish in image 1: a deep, very thin, hatchet-shaped silver body like a polished mirror, a big upward-looking eye, a small upturned mouth, a narrow tail stalk with a small tail fin, two neat rows of small glowing blue light organs along the lower edge of the belly; shown once large in side view, and below it a small school of five of them swimming next to the bare open hand of the girl Kira from image 3, each fish about the length of her palm and much smaller than her hand plus fingers. RIGHT HALF: the sea angel, anatomy exactly like the real animal in image 2: a small translucent glassy body tapering to a pointed tail, a bright orange-red gut and head glowing through the clear body, two small transparent wing-like flaps near the head that it flaps to swim; shown once large, and below it a sea angel floating above the fingertip of Kira's bare hand, as small as her fingertip, about 3 cm long.
