Example Sentences
Applying these principles to Crustacea, he concluded that the shrimp Peneus with its long direct development gave the best and truest picture of the ancestral history of the Malacostraca, and that accordingly the nauplius and the zoaea larvæ represented important ancestral stages.
For example, the larva of marine crabs was formerly described as a distinct genus under the name of Zoaea, and in the earlier part of the nineteenth century a lively controversy on the question was carried on between a retired naval surgeon who hatched Zoaea from the eggs of crabs, and an eminent authority who was Professor at Oxford and a Fellow of the Royal Society, and who maintained that Zoaea was a mature and independent form.
In the end taxonomy had to be altered so as to conform with the fact of development, and the name Zoaea disappeared altogether as that of an independent genus, persisting only as a convenient term for an important larval stage in the development of crabs.
As an instance of this may be mentioned the mandibular palp of those Crustacea with zoaea larvae.
