Ontogenetic allometry showed no interspecific variation and <7 mm standard length ( L S ) larvae of both species occupied similar morphospace, but larger G. marmoratus showed increased body depth while larvae of S. sanguineus developed a flattened head and maintained a hydrodynamic body. Estimated developmental timing suggests that larval body shape changes were faster in G. marmoratus than in S. sanguineus prior to settlement.enacceso restringidoAquatic ScienceEcology, Evolution, Behavior And SystematicsFisheriesMarine And Freshwater Biologyarticle
