Leptometra is a genus of free-swimming, stemless crinoids.
==Characteristics== Members of this genus have no stems but have five pairs of feathery arms arising from a central concave disc. There are a number of long cirri or unbranched appendages on a low, cone-shaped dorsal ossicle, a bone-like structure in the centre of the disc.
