A new species of jumping spider was named Jotus karllagerfeldiI after Karl Lagerfeld due to its distinctive black-and-white colors resembling the designer's style. The species was discovered in the Godeffroy Collection, alongside seven other new species found across Australia.
A recent study published in Systematic Biology confirms horseshoe crabs belong to the arachnid family tree, challenging previous hypotheses. By analyzing genetic data and considering multiple analysis methods, researchers found a high degree of confidence that horseshoe crabs are part of the arachnid radiation.
A new species of tarantula, Ceratogyrus attonitifer, was recently discovered in Angola with a distinctive 'horn' protruding from its back. The species is part of the horned baboon spider group and has been found to have a soft, characteristically longer 'horn', unlike other species in the same group.
Researchers Emily Setton and Prashant Sharma discovered that spiders and scorpions co-opted leg genes to build their heads. This genetic adaptation allows scientists to trace the evolutionary history of these animals, revealing a complex web of genetic mechanisms underlying their diversity.
A new species of arachnid resembling a spider with a tail has been discovered in 100-million-year-old amber from Myanmar. The finding provides insight into arachnid evolution and suggests that tailed descendants may still be alive today.
Researchers have identified 18 new species of pelican spiders in Madagascar, known for their unique biology and hunting behavior. The discovery sheds light on the island's biodiversity and emphasizes the need to conserve its shrinking forests and unique species.
Research reveals ground spiders produce exceptionally tough and stretchy silk, but less sticky than other piriform silks, allowing them to ambush prey quickly. The silk's unique properties are adapted to overcome larger prey and arachnids, highlighting the trade-offs in their hunting strategy.
A new Colombian tarantula species has been discovered, featuring extraordinary defensive hairs that challenge traditional attack methods. The species, Kankuamo marquezi, is named after Gabriel Garcia Marquez and honors an indigenous people from the Caribbean coast.
Researchers manipulated video footage to study male jumping spiders' behavior, finding that size assessment influences their decision-making. Larger spiders are less likely to approach smaller opponents, while smaller spiders can't scare away larger opponents.
Ticks carrying Lyme disease are increasingly found in new areas of the US, with a study suggesting southern ticks migrated northwards. Understanding these movements is crucial to identifying factors driving population shifts and reducing public health risks.
Researchers created a visual atlas and dictionary of terms for camel spider jaws, revealing a single evolutionary origin of the flagellum. The flagellum plays a crucial role in reproduction and is found on the jaws of adult males in most species.
Researchers used exceptionally preserved fossils and computer graphics to recreate the most likely walking gait of a 410-million-year-old arachnid. The study, published in the Journal of Paleontology, provides new insights into the evolution of early land animals.
A newly discovered 305-million-year-old fossil fills in the evolutionary tree for primitive harvestmen, providing evidence that they once had two pairs of eyes. This rare find allows scientists to study the anatomy of ancient arachnids in unprecedented detail.
Researchers have discovered a 305-million-year-old harvestman fossil with two sets of eyes, challenging previous assumptions about the evolutionary history of arachnids. The fossil's exceptional preservation allows scientists to study its anatomy in unprecedented detail.
A recent study published in Biological Conservation found that spider populations are negatively affected by human activities such as habitat fragmentation, fire, and pesticides. The research, which analyzed 173 scientific papers, suggests that spiders are not exempt from the risks caused by human action.
Scientists at Ohio State University have found evidence of silk-spinning structures on the fossilized body of an ancient arachnid, called Aphantomartus pustulatus. The finding suggests that silk-spinning has been around for a long time and could provide insights into the early evolution of arachnids and life on land.
