Abstract

The skeleton of the acanthopterygian sea bass (Dicentrarchus labrax L.) normally consists of acellular bone. Individuals with a spinal deformity called lordosis, however, display chondroid bone at the articular surfaces of the affected vertebrae. Chondroid bone is well known in teleosts from sites subjected to mechanical stress. This skeletal tissue intermediate between bone and cartilage appears to meet the demand for an accelerated local growth rate, combined with the need for shear resistant support (Huysseune, 2000). We performed an ontogenetic histological study of chondroid bone in sea bass vertebrae. Chondroid bone forms from mesenchymal tissue in (presumably) high compression sites in between the postand prezygapophyses of two consecutive vertebrae. The mechano-regulatory pathway hypothesis (Prendergast et al., 1996) is employed to provide mechanistic explanation of vertebral deformations in lordotic sea bass
