spider : any of an order (Araneae synonym Araneida) of arachnids having a short, usually unsegmented abdomen linked to the cephalothorax by the pedicel, chelicerae modified into poison fangs, and two or more pairs of spinnerets at the posterior end of the abdomen for spinning threads of silk for various uses (as in making cocoons for their eggs or webs to catch prey) — Webster See also OneLook
Spiders are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat with the exceptions of air and sea colonization. — Wikipedia
Biology is the scientific study of life. Biologists study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations. Biologists also study and classify the various forms of life, from prokaryotic organisms such as archaea and bacteria to eukaryotic organisms such as protists, fungi, plants, and animals. — Wikipedia

The complete skeletal remains of a spider monkey -- seen as an exotic curiosity in pre-Hispanic Mexico -- grants researchers new evidence regarding social-political ties between two ancient powerhouses: Teotihuacán and Maya Indigenous rulers. The remains of other animals were also discovered, as well as thousands of Maya-style mural fragments and over 14,000 ceramic sherds from a grand feast. These pieces are more than 1,700 years old.
- Mapping Lyme disease out weston November 21, 2022 at 6:07 pm
Tick bites can transmit Lyme disease. But even knowing where these ticks live doesn't necessarily mean you can predict the disease in humans. It's only one part of a broader picture which includes human behavior and the habits of the parasite's carriers.

Tick-borne pathogens, known for causing illnesses such as Lyme disease, are on the rise in Central Canada -- presenting new risks in areas where they were never previously detected. The findings demonstrate the need for more comprehensive testing and tracking to detect the spread and potential risk of tick-borne pathogens to human and wildlife populations throughout Canada.

When it comes to spider love, female widow spiders hold the key to attracting mates, potentially adjusting their web's attractiveness to lure males, according to new research. A study led by Simon Fraser University's resident 'spider man,' PhD candidate Andreas Fischer, reveals new details about how female false widow spiders (Steatoda grossa) communicate using pheromones--and suggests they can build more attractive webs-- to lure mate-seeking males by adjusting the pH level of their […]

Many of Australia's natural places are in a poor state. While important work is being done to protect particular species, we must also take a broader approach to returning entire ecosystems to their former glory— a strategy known as "rewilding".

Citizen science is touted as a way for the general public to contribute to producing new knowledge. But citizen science volunteers don't always represent a broad cross-section of society. Rather, they're often white, male, middle-aged, educated and already interested in science.
