Resumen
Larval body shape changes and developmental timing were examined in two clingfish species from the south-east Pacific Ocean, Gobiesox marmoratus and Sicyases sanguineus. Ontogenetic allometry showed no interspecific variation and <7mm 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. Regular 2015 FONDECYT FONDECYT
