(Taylor & Francis Ltd, 2015-04)
Tanais dulongii (Audouin, 1826) is a small benthic crustacean with separate sexes and a marked sexual dimorphism characterized by a cephalothorax narrowed anteriorly, larger chelae (claws) and a pair of tiny genital cones ...
Structure and development of the egg of the glossiphoniid leech Theromyzon rude: Characterization of developmental stages and structure of the early uncleaved egg
(1987)
Some aspects of the reproductive biology of the glossiphoniid leech, Theromyzon rude, under laboratory conditions, and the staging and structure of its uncleaved egg were studied. Sexually mature animals form breeding ...
The Vesicles of Phyllomedusa sauvagii (Anura: Hylidae) Nest
(Brazilian Society of Herpetology, 2011-04)
Phyllomedusa sauvagii lays its eggs surrounded by peculiar vesicles in nests made with tree leaves and, until now, the function of these vesicles was thought to be for maintaining moisture. The histomorphological and ...
Comparative study of the ovarian morphology in the order Polydesmida (Diplopoda) and description of unusual structures in the female reproductive systemEstudo comparativo da morfologia ovariana na ordem Polydesmida (Diplopoda) e descrição de estruturas incomuns do sistema reprodutor feminino
(2013-01-01)
Polydesmida is the largest order in the class Diplopoda in terms of the number of species, genera and families, but there are few studies of the ovarian morphology of species in this order. This study aimed to perform a ...
