Ameboid movement is exclusive to living things that have no shape, and which can actually change their shape, namely cells and unicellular organisms. Learn about specific aspects of ameboid movements, such as pseudopodia and cytoplasmic flow, and discover the role of plasmagel and plasmasol in ...
A roundworm, also known as a nematode, is a very small worm that lives in the intestines of people, pigs, and other animals. Discover the physical characteristics and taxonomic classification of roundworms as well as examples of roundworms that infect humans and how these infections are treated...
Although the cuckoo is famous as a brood parasite, relatively few cuckoo species actually demonstrate parasitism. The vast majority prefer to nest and raise their own young. Among species which have evolved as brood parasites, the eggs are often similar in color and size to those of specific bi...
