Relative growth, morphological sexual maturity, heterochely, and handedness in Panopeus occidentalis (Brachyura, Panopeidae)
(2018-04-03)
Studies on relative growth and sexual maturity are important to understand the reproductive biology of a species. The aims of this study were to determine the relative growth and to estimate the size of Panopeus occidentalis ...

ALLOMETRIC GROWTH, SEXUAL MATURITY, AND ADULT MALE CHELAE DIMORPHISM IN AEGLA FRANCA (DECAPODA: ANOMURA: AEGLIDAE)
(CRUSTACEAN SOC, 2009)
Allometric growth analysis on chelac dimensions vs. carapace length (CL) was employed to estimate average size at the onset of morphometric maturity (= puberty molt) and sexual dimorphism regarding the pair of chelae in ...

Social structure, sexual dimorphism and relative growth in the ghost shrimp Callichirus seilacheri (Bott, 1955) (Decapoda, Axiidea, Callianassidae) from the tropical eastern Pacific
(2018-09-14)
We analyzed the social structure, sexual dimorphism and relative growth in the burrowing shrimp Callichirus seilacheri from the tropical eastern Pacific. To this end, 456 individuals of C. seilacheri were collected during ...
Functional morphology of comminuting feeding structures of Trichodactylus borellianus (Brachyura, Decapoda, Trichodactylidae), an omnivorous freshwater crab
(Elsevier, 2017-07)
Crustaceans exhibit great diversity of feeding structures with morphological traits that are useful to infer the general trophic habits of species. In this study, we analyzed the functional morphology of comminuting feeding ...
