Developmental morphology of mouthparts and foregut of the larvae and postlarvae of Lepidophthalmus siriboia Felder & Rodrigues, 1993 (Decapoda: Callianassidae)

In this study, the gross morphology of the mouthparts and foregut of the ghost shrimp Lepidophthalmus siriboia were investigated from larvae and postlarvae reared in the laboratory. The mouthparts (maxillae and maxillipeds) of the zoeae have a reduced number of setae and spines (or is absent in some...

A morfologia dos apêndices bucais e o estômago de larvas e pós-larvas de Lepidophthalmus siriboia cultivados em laboratório foi investigada. Os apêndices bucais (maxilas e maxilípedes) durante os estágios zoeae apresentam número reduzido de cerdas e espinhos, ou mesmo, ausentes em alguns indivíduos. O estômago aparece pouco desenvolvido, com poucas cerdas pequenas nas câmaras cardíaca e pilórica. Contrariamente, após a metamorfose para o estágio megalopa, todas estas estruturas bucais possuem muitas cerdas, e o estômago apresenta um moinho gástrico bem desenvolvido com dois fortes dentes laterais. No estágio juvenil ocorre incremento de cerdas e espinhos em todas estruturas bucais e o estômago torna-se mais especializado. Estas observações sugerem fortemente que as zoeae de L. siriboia têm desenvolvimento lecitotrófico, mas que as megalopae e juvenis passam a ingerir alimentos exógenos. ABRUNHOSA, F. A.; LIMA, J.
