but seldom related to oxygen consumption.
Conversely, metabolic changes (measured as oxygen consumption)
are recorded throughout development in many
kinds of embryos such as crabs (Ferna´ndez et al., 2003),
cuttlefish (Cronin and Seymour, 2000), echinoids, bivalves
and asteroids (Hoegh-Guldberg and Manahan, 1995), yet few
studies describe the accompanying morphological changes.
