The approach taken in this chapter stresses the broader functional aspects of brachyuran
morphology and anatomy, and particularly how complex patterns of evolution have allowed …

The genus Callinectes and its 14 species are reevaluated. Keys to identification,

Organisms have been important agents of selection throughout the history of life. The
processes and outcomes of this selection are the subject of this review. Among these …

From humans to hermit crabs to deep water plankton, all living things compete for locally
limiting resources. This universal truth unites three bodies of thought--economics, evolution …

Abstract The Guamunian xanthids Carpilius maculatus (L.), C. convexus (Forskal), and
Eriphia sebana (Shaw & Nodder), and the parthenopid Daldorfia horrida (L.), possess large …

Brachyuran crabs are important predators of molluscs, influencing both the distribution and
characteristics of their prey. Crab master-claw strength, as inferred from morphological …

Abundant fossil material of extinct brachyurans has revealed morphological details hitherto

Cheliped construction, in particular the teeth pattern on chelae fingers is considered as most
important character suit (along with burrowing/swimming apparatus) for the diagnosis of …

The cephalopod nervous system is the most complex of any invertebrate nervous system.
Although species-specific differences exist, its high level of complexity almost certainly is …
