The term comes from the Greek γυνή (gynē) 'female', ἀνήρ (anēr) 'male', and μορφή (morphē) 'form', and is used mainly in the field of entomology. Gynandromorphism is most frequently recognized in organisms that have strong sexual dimorphism such as certain butterflies, spiders, and birds, but has been recognized in numerous ...
A male Eresus sandaliatus. Sexual selection in spiders shows how sexual selection explains the evolution of phenotypic traits in spiders.Male spiders have many complex courtship rituals and have to avoid being eaten by the females, with the males of most species surviving only a few matings and consequently having short life-spans.
The Australian Reptile Park recently recorded its largest male funnel-web spider yet, CNN reported. According to the zoo, which is located north of Syndey, Australia, the spider measures a ...
Cupiennius salei, from the genus Cupiennius also commonly called the Tiger bromeliad spider, which are large bodied, actively-hunting spiders that are part of the family Trechaleidae. In the mid-1950s it was realised that the spider is an ideal model for biological research because of their large size, predictable behaviour, and ease of ...
Female fireflies are usually stationary, Li explained, so only male fireflies tend to get trapped in — and are more likely to be lured to — spider webs. An orb-weaving spider is shown here ...
The variance in male body size of T. plumipes is 44.4, twice that of other male spiders of similarly sized species. This is because smaller males are less likely to be detected and cannibalized by females before copulation, but larger males can exclude small males from the central hub of the web where mating takes place.
The spider is a pale to dark brown colour with several chevron markers and lighter stripes around its legs, similar to D. scriptus. [2] The legs are banded with brown/black annulations on the femora and reddish-brown/black annulations on the tibia.
