The observation of male and female crab spiders mimicking a flower presents a novel insight into animal behavior. What is the most significant implication of this discovery?
The observation of male and female crab spiders mimicking a flower presents a novel insight into animal behavior. What is the most significant implication of this discovery?
- It suggests a new form of symbiotic relationship where species cooperate to enhance survival and predation, expanding their ecological niche. (correct)
- It indicates that male crab spiders are evolving to resemble flowers independently of females, to avoid competition.
- It confirms that camouflage behavior is exclusive to female crab spiders, with males playing a supportive role.
- It proves that crab spiders are the only species capable of altering their physical appearance to match their environment.
Given that female crab spiders commonly camouflage, why is the discovery of cooperative mimicry with males considered significant?
Given that female crab spiders commonly camouflage, why is the discovery of cooperative mimicry with males considered significant?
- Because it demonstrates that male crab spiders are capable of changing colors, a trait previously believed to be exclusive to females.
- Because it provides the first evidence of cooperative mimicry in any species, highlighting a sophisticated level of interaction for survival and predation. (correct)
- Because it reveals that female crab spiders are incapable of effective camouflage without the assistance of males.
- Because it contradicts previous assumptions of solitary behavior in crab spiders, regardless of sex.
The researchers, Wu and Gao, suggest that cooperative mimicry could expand the niche of both male and female crab spiders. What does 'expanding the niche' most likely refer to in this context?
The researchers, Wu and Gao, suggest that cooperative mimicry could expand the niche of both male and female crab spiders. What does 'expanding the niche' most likely refer to in this context?
- Increasing the physical size of their habitat by migrating to different regions.
- Enhancing their ability to avoid predators and attract prey through improved camouflage, leading to greater survival and reproductive opportunities. (correct)
- Broadening their diet to include a wider variety of prey species.
- Developing new methods of communication to attract mates from different spider species.

Study Notes
- Shi-Mao Wu and Jiang-Yun Gao, environmental scientists, observed a male and female crab spider resembling a single flower in a rainforest in China's Yuan Province.
- The male spider was disguised as the pistils and stamens.
- The female spider resembled the flower's lighter petals.
- Wu initially mistook the male spider for part of the flower.
- Female crab spiders commonly camouflage themselves to blend in with flowers, sometimes changing colors.
- Camouflage helps female crab spiders avoid predators and catch prey.
- Camouflaging behavior is rare in male crab spiders, which are smaller and darker.
- This is the first documented instance of cooperation mimicry in any species.
- Cooperation mimicry requires both participants to create a convincing camouflage.
- Wu and Gao's findings were revealed on March 1, 2024.
- Cooperation may expand the niche of both female and male spiders in mimicry systems.
- Cooperating individuals may experience improved survivorship and predation efficiency.
