Embryology of the spider crabs Leurocyclus tuberculosus (H. Milne-Edwards & Lucas 1842) and Libinia spinosa (H. Milne-Edwards 1834) (Brachyura, Majoidea)

The embryonic development of the spider crabs Leurocyclus tuberculosus and Libinia spinosa was divided into five peri-ods based on the differentiation of: I) cleavage, II) embryonic primordium, III) optic lobes, IV) optic lobes pigmented and V) chromatophores presence. Different traits such as spine...
