In teleosts: Anatomical cluster that is the result of fusion of preural centrum 1 with one or more adjacent ural centra[AAO]; Rodlike caudal bony structure unique to anurans that lies within a compartment formed by the elongated, anteriorly oriented pelvic girdle. The urostyle is formed by the fusion of the coccyx and the hypochord[AAO]. [ AAO:0000732 TAO:0000158 ]

In zebrafish, it is composed of preural vertebra 1 and ural centra 1 and 2. The number of ural centra that become fused with preural centrum 1 varies among teleost subgroups. Because of varying developmental origins the urostyle may not be homologous across species.[TAO]
