The damage to books that is commonly attributed to "bookworms" is often caused by the larvae of various types of insects, including beetles, moths, and cockroaches, which may bore or chew through books seeking food. The damage is not caused by any species of worm. Some such larvae exhibit a superficial resemblance to worms and are the likely ...
Other species of Olavius are also known to have similar symbioses with both sulfide-oxidizing and sulfate-reducing bacteria in the same worm. [ 4 ] [ 8 ] The primary sulfur-oxidizing symbiont, known as "Gamma1", is closely related to the primary symbionts of other species of gutless oligochaetes in the Phallodrilinae , and also to the symbionts ...
After the bacteria kill the host, they proliferate on the host's dead body. The Heterorhabditis then feeds on this new growth of bacteria for development. [ 14 ] In both cases of feeding, the parasitic nematodes make direct use of the host's body, possible only through the evolutionary pathway aided by phoresy.
Unlike free-living bacteria, it contains no genes for anaerobic glycolysis or genes involved in the biosynthesis and regulation of amino acids and nucleosides. In this regard, it is similar to mitochondrial genomes; in both cases, nuclear (host) resources are used. ATP production in Rickettsia is the same as that in mitochondria.
There’s an invasive species of worm making itself known in Texas once again—the hammerhead flatworm. These worms are toxic, hard to kill, and dangerous to native critters like earthworms, but ...
It is estimated viruses kill 20% of this biomass each day and that there are 15 times as many viruses in the oceans as there are bacteria and archaea. Viruses are the main agents responsible for the rapid destruction of harmful algal blooms , [ 40 ] which often kill other marine life. [ 54 ]

Along with the shift in genres went a diversification of life-forms and life-cycles, including blood-drinking plants like the "strange orchid" in The Thing from Another World (1951), aliens like H. G. Wells's Martians in The War of the Worlds, "cyber-vamps" like "The Stainless Steel Leech" and "Marid and the Trail of Blood", and psychic ...
