The scaphoid, lunate, and triquetrum are connected by dorsal, volar, and interosseous ligaments. In this state, the distance between the scaphoid and lunate bones is increased. The lunate bone is the most frequently dislocated carpal bone. Geometric microliths may be triangular, trapezoid or lunate. The caudal fin has variously been described as either lunate or semi-lunate. The lunate receives its blood supply from dorsal and palmar branches. Fruits are oblong or ellipsoidal; they are strongly curved, falcate, bent or lunate shaped. The lunate is found within the proximal row of carpal bones. The proximal surface of the lunate bone is smooth and convex, articulating with the radius. It connects with the pisiform, hamate, and lunate bones. The lunate is a crescent-shaped carpal bone found within the hand. The fish have small mouths, relatively large pectoral fins, and rounded to lunate tail fins. Laminar microliths can also sometimes be described as trapezoidal, triangular or lunate. Adjacent on the radial side is the capitate, and proximal is the lunate.
