Geographic variation of skeletal ontogeny and skull shape in the harbour porpoise (Phocoena phocoena)
Galatius, A.; Gol’din, P. E.
Canadian Journal of Zoology (2011)
All extant porpoise species show paedomorphic skeletal traits. These traits are hypothesized to be connected with rapid growth to reproductive size and could thus show geographic variation according to ecological…
