New spider species with serrated fangs found in Nerja cave
Scientists have discovered a new species of spider in the Nerja cave in Spain. The spider measures only about 0.04 inches in diameter.
An extraordinary discovery was made in the Nerja cave in Málaga, Spain: a new species of spider named Anapistula delrosalae. The cave is well-known for its archaeological finds and attracts hundreds of thousands of tourists each year.
The discovery was facilitated by a trapping project conducted from 2000 to 2001, with additional traps set from 2017 to 2019. Tumulus-type traps were used, filled with propylene glycol and beer in a 4:1 ratio, and baited with sobrasada, a Spanish sausage.
Researchers found a spider in one of the traps that differs from other Anapistula species in Europe. This new species has a serrated fang edge; it is slightly larger and more transparent than other species.
The research team believes this species is widespread throughout the cave, as egg cocoons and additional individuals were observed. However, the description of the new species is based solely on female specimens found in the traps.
New discoveries in the animal world
Recently, a new species of herring was discovered in the Baltic Sea. This species differs from traditional plankton-eating herrings as it is predatory, larger, and fattier, making it more attractive to consumers. Genetic studies have revealed two subpopulations of this species, which may impact the marine ecosystem.
A Polish-Venezuelan expedition reached the top of Tramén Tepui in Venezuela, where they discovered new endemic species of butterflies and frogs. Known for its high rate of endemism, the Pantepui region offers unique conditions for evolutionary research. These discoveries bring us closer to understanding the origins of the area's fauna.
The Tramén Tepui mountain, with its challenging climate and inaccessibility, presented a challenge to scientists. The expedition required specialized equipment, and the discoveries of butterflies and frogs are significant contributions to biogeographical research.
These discoveries show how diverse and unexplored our planet's ecosystems still are. Both the new species of herrings and the findings on Tramén Tepui highlight the importance of field research and its impact on understanding evolutionary processes and biodiversity conservation.
