Decapods are one of the most diverse crustacean orders, with around 17,500 extant species [...]

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...

Like many others, I see Crump et al. (2022) as a milestone for improving upon previous guidelines and extending their framework to decapod crustaceans. Their proposal would benefit from firm evolutionary foundation by adding the comparative measurement of life-history complexity ninth criterion attributing sentience nonhuman animals.

Many decapod crustaceans with sexual dimorphism in body size are economically significant species for fisheries and aquaculture, making monosex culture a desirable practice to increase farmers' yield profits. It is well established that the male-specific androgenic gland (AG) mediates masculinization decapods by producing secreting insulin-like AG hormone (IAG). However, IAG not sex-determining...
