What is the biological term for the size disparity observed between male and female *Dysdera crocata*?
Answer
Sexual dimorphism
The marked difference in size between adult males (around 5–6 mm body length) and adult females (8–10 mm body length) in the woodlouse spider is an example of a common biological phenomenon in arachnids. This difference, where one sex is visibly larger or distinct from the other, is formally termed sexual dimorphism. In the case of *Dysdera crocata*, the female is notably larger and often bulkier than the male, a trait related to reproductive roles and potentially the energy required to carry eggs.
