Smale, Will. Separating the curds from the whey: Cheddar cheese has gone a long way since it was invented in the quaint Somerset village of the same name back in the Middle Ages. BBC News, Somerset. 21 August 2006.
Since they are in the phylum Nematoda, hookworms have a psuedocoelom that they use for digesting food. -Hookworm eggs gain nutrients via the feces of the host that it has inhabited. -In the larval stage, hookworms are free-living in the soil.
A hookworm produces an anticoagulant in its saliva so the host's blood does not clot at the site the hookworm attaches. If the worm moves from that site to reattach itself at another, the first site may continue to bleed, sometimes seriously. Hookworms, especially A. caninum can cause severe disease. By feeding on the blood of the host, hookworms can rapidly cause anemia. The mucous membranes e.g., gums, will appear pale, the animal will become weak, and sometimes black, tarry stools can be seen. There may be vomiting and diarrhea.
