A new species of xanthid crab (Brachyura: Xanthidae) is described from the Bohol Sea in the central Philippines. Xanthias joanneae sp. nov. is most similar in morphology to X. maculatus Sakai, 1961 (type locality: Sagami Bay, Japan), particularly in the presence of distinctive ocelli on the carapace and pereopods. It can be separated from this species by the greater number of ocelli on the dors...

Phylogenetic relationships among all of the major decapod infraorders have never been estimated using molecular data, while morphological studies produce conflicting results. In the present study, the phylogenetic relationships among the decapod basal suborder Dendrobranchiata and all of the currently recognized decapod infraorders within the suborder Pleocyemata (Caridea, Stenopodidea, Achelat...

We outline a framework for evaluating scientific evidence of sentience, focusing on pain experience. It includes eight neural and cognitive-behavioural criteria, with confidence levels each criterion reflecting the reliability quality evidence. rationale apply our to controversial sentience candidate: decapod crustaceans. have either high or very that true crabs (infraorder Brachyura) satisfy f...

Adaptations to a terrestrial lifestyle occurred convergently multiple times during the evolution of the arthropods. This holds also true for the "true crabs" (Brachyura), a taxon that includes several lineages that invaded land independently. During an evolutionary transition from sea to land, animals have to develop a variety of physiological and anatomical adaptations to a terrestrial life st...

Bu çalışma Aralık 2012- Kasım 2013 ayları arasında Güney Doğu Karadeniz’de beam trol ile avlanan Liocarcinus depurator’un (Crustacea: Decapod: Brachyura) üreme özelliklerini belirlemek amacıyla yürütülmüştür. İyidere, Merkez ve Çayeli istasyonlarından 2 m genişliğinde kirişli (Beam trol) kullanılarak 0-30+ derinliklerde örnekleme yapılmıştır. Toplamda 2715 adet L. depurator (%39,4 yumurtasız di...
