Le livre suivant représente une description détaillée de diverses larves de cordés et de non-cordés. Les larves de plusieurs espèces sont importantes à des fins écologiques et économiques. La larve est une étape d'existence auto-alimentation et de natation libre qui ressemble moins aux adultes. Ils ne sont généralement pas pris en charge par leurs changements structurels et physiologiques pour atteindre l'âge adulte. Le processus est appelé métamorphose et les changements sont appelés changements métamorphiques. Les organismes traitant les stades larvaires pondent des œufs minuscules avec très peu (microlecithal) ou pas de matériau jaune. Signification des stades larvaires : ils aident à la dispersion des espèces, les stades larvaires sont utiles pour trouver les homologies et l'affinité de divers groupes, et la nature alimentaire et reproductive ou les tendances évolutives peuvent être comprises. Le livre suivant représente un nombre total de 63 formes larvaires, certains montrent divers comportements importants comme la métamorphose rétrogressive (par exemple, Têtard ascidien) et néoténie (par exemple Axolotl)

Larva of several species are significant in ecological and economical purposes. Larva is a self feeding and free swimming stage of existence that bears least resemblance to the adults. They are generally not looked after by their structural as well as physiological changes to attain the adulthood. The process is called metamorphosis and changes are called metamorphic changes. Organisms processing larval stages lay minute eggs with a very little (microlecithal) or no yolk material. Significance of larval stages: They help in the dispersal of species, the larval stages are useful in finding the homologies and affinity of various groups, and the feeding and reproductive nature or evolutionary trends may be understood. The following book represents a total numbers of 63 larval forms, some shows various important behaviors like retrogressive metamorphosis (eg. Ascidian tadpole) and neoteny (eg. Axolotl). 112 pp. Englisch. N° de réf. du vendeur 9786202528115
