Resumen:
Octopuses are intriguing organisms that, together with squids and
cuttlefishes, form the extant coleoid cephalopods. This group includes
many species that can potentially be used as models in the fields of
biomedicine, developmental biology, evolution, neuroscience and even for
robotics research. The purpose of this work is to first present a simple
method for maintaining Octopus insularis embryos under a laboratory
setup. Second, we show that these embryos are suitable for detailed
analyses of specific traits that appear during developmental stages,
including the eyes, hearts, arms, suckers, chromatophores and Kolliker's
organs. Similar complex traits between cephalopods and vertebrates such
as the visual, cardiovascular, neural and pigmentation systems are
generally considered to be a result of parallel evolution. We propose
that O. insularis embryos could be used as a model for evolutionary
developmental biology (or EvoDevo) research, where comparisons of the
morphogenetic steps in the building of equivalent organs between
cephalopods and known vertebrate model systems could shed light on
evolutionary convergences and deep homologies.
