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

Spider Glossary (Spiders from Europe, Australia and some immunology)


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

Arachnology is the scientific study of spiders and related animals such as scorpions, pseudoscorpions, and harvestmen, collectively called arachnids. Those who study spiders and other arachnids are arachnologists. — Wikipedia

    Hitherto, scientists have not fully understood why ticks are such dangerous disease vectors. A research team now shows that tick saliva inhibits the skin's defense function, thereby increasing the risk of diseases such as tick-borne encephalitis (TBE) or Lyme disease.

    The Longhorned tick causes the loss of millions of dollars in agricultural revenue to cattle producers worldwide, and it is now in northern Missouri. Originally found in eastern Russia and the Australasian region, this tick was first found in the United States in 2017 in New Jersey. It has since reached the Mid-Atlantic, New England and Midwestern regions of the U.S., and now has been discovered in northern Missouri.

    Researchers have discovered that spider silk proteins can be fused to biologically active proteins and be converted into a gel at body temperature. One of the goals is to develop an injectable protein solution that forms a gel inside the body, which could be used in tissue engineering and for drug release, but also make gels that can streamline chemical processes where enzymes are used.

    A team of researchers at Macquarie University, in Australia, working with two colleagues from Universität Hamburg, in Germany, has uncovered the means by which the Australian ant-slayer spider is able to capture and eat the much larger banded sugar ant. Their study is published in the Proceedings of the National Academy of Sciences.

    A three-year study in northeastern Illinois and northwestern Indiana found that—even at small scales—emergent wetlands or ponds support many wetland bird species. The study also found that, at least in the years surveyed, the level of urbanization had little effect on most of the studied species' use of such sites, provided the right kinds of habitat were available.
