Sexual size dimorphism is one of the most striking animal traits, and among terrestrial
animals, it is most extreme in certain spider lineages. The most extreme sexual size …

Instances of sexual size dimorphism (SSD) provide the context for rigorous tests of biological
rules of size evolution, such as Cope's rule (phyletic size increase), Rensch's rule (allometric …

Female spiders and praying mantises are renowned for their cannibalism of male partners
