Regionalization of the axial skeleton in the 'ambush predator' guild--are there developmental rules underlying body shape evolution in ray-finned fishes?

Beloniformes Based on independent contrasts, the relationship between the number of abdominal vertebrae and log FR is highly significant (r = 0.61, P = 1.42 × 10 -8 ; df = 66; Figure 7 a); that between the number of caudal vertebrae and FR is also significant but the correlation is not as strong (r = 0.4, P = 3.30 × 10 -4 ; df = 66), and that between the number of abdominal and caudal vertebrae is also significant and positive (r = 0.57, P = 2.33 × 10 -7 ; df = 66; Figure 7 b).
