Sustainability Greater sustainability and its many benefits can be achieved for all buildings, homes, organisations and communities. Internationally recognised as the developers of sustainability standards codes and methodologies (such as BREEAM) for buildings, homes and communities, our expert team offers a comprehensive range of cradle to grave sustainability services. We can also help to reduce the environmental impact of construction processes, materials and operations, and provide leading edge information and advice on all aspects of the sustainability of:
Spiders obtain their oxygen through four respiratory organs located on the underside of their abdomens. These organs are arranged into two pairs, an anterior pair at the very front end of the abdomen, and a posterior pair behind the anterior pair.
Answer: Nearly all spiders subdue their prey by injecting venom through their fangs, which operate much like a pair of hypodermic needles. Besides the paralytic action of the venom compounds, the spider regurgitates digestive fluids onto the prey to digest it, working more or less like a meat tenderizer. Once the prey begins to liquefy, the spider uses its jaws and pedipalps to further masticate its meal. The âmeat ballâ is then slowly imbibed by the mouthparts, taken in mostly in liquid form. Spiders in the obscure family Uloboridae do not possess venom glands, but the rest of the feeding process remains the same.
