Newly discovered spider species adds intrigue to Nerja cave

Scientists have discovered a new species of spider in the Nerja cave in Spain. The spider measures only about 1 millimetre in diameter.

Scientists made an extraordinary discovery in the Nerja cave in Málaga, Spain. The new species of spider, named Anapistula delrosalae, was found in the cave, which is renowned for archaeological finds and attracts hundreds of thousands of tourists each year.

This discovery was facilitated by a trapping project from 2000-2001 and new traps set from 2017-2019. Tumulus-type traps were filled with propylene glycol and beer in a 4:1 ratio, baited with sobrasada, a Spanish sausage.

In one of the traps, researchers found a spider that differs from other Anapistula species in Europe. This new species has a serrated fang edge, is slightly larger, and more transparent than other species.

The research team believes this species is widespread throughout the cave, where egg cocoons and additional individuals were also observed. However, the new species description 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, differing from traditional plankton-eating herrings. This new species is predatory, larger, and fattier, making it more attractive to consumers. Genetic studies have revealed the existence of two subpopulations of this species, potentially impacting the marine ecosystem.

A Polish-Venezuelan expedition reached the top of Tramén Tepui in Venezuela, discovering new endemic species of butterflies and frogs. The Pantepui region, known for its high rate of endemism, offers unique conditions for evolutionary research. These discoveries enhance our understanding of the origins of the area's fauna.

The Tramén Tepui mountain, with its challenging climate and inaccessibility, posed a challenge to scientists. The expedition required specialized equipment, and the discoveries of butterflies and frogs are significant contributions to biogeographical research.

These discoveries demonstrate how diverse and unexplored our planet's ecosystems remain. Both the new species of herrings and the findings on the Tramén Tepui mountain highlight the importance of field research and its impact on understanding evolutionary processes and biodiversity conservation.
