Osedax is a genus of deep-sea siboglinid polychaetes, commonly called boneworms, zombie worms, or bone-eating worms. Osedax is Latin for "bone-eater". The name alludes to how the worms bore into the bones of whale carcasses to reach enclosed lipids, on which they rely for sustenance. They utilize specialized root tissues for bone-boring.
Earthworms use, in addition to the digestive proteins, a class of surface active compounds called drilodefensins, which help digest plant material. [29] Instead of being coiled like a mammalian intestine, in the earthworm's intestine a large mid-dorsal, tongue-like fold is present, called a typhlosole , with many folds running along its length ...
In ecosystems, earthworms such as Lumbricus rubellus increase the rate of transfer between trophic levels by making it easier for plants to uptake nutrients. In food chains, earthworms such as Lumbricus rubellus are primary consumers whose role is converting the energy synthesized by photosynthetic plants into food for animals at higher trophic ...
In the soil system, L. terrestris worm casts have a relationship with plants which can be seen in such scenarios as plant propagation from seed or clone. Worm casts initiate root development, root biomass, and in effect, increase root percentage as opposed to the soil and soil systems without worm casts.
The worms were originally transferred through the horticultural trade, probably in the soil bulbs of European plants carried to the Americas. Some earthworms have been brought over to be used as bait for fishing and escaped or got released. For example, at least one species of earthworm was introduced in Alaska as bait for anglers. [19]
How do worms and insects stack up against animal meats? Despite a wide range of nutrition for edible worms and insects, many seem to have similar if not greater nutritional profiles than animal meats.
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
It’s a simple question with a complicated answer. Dogs eat grass all the time, but the reasons why are varied. Technically, eating non-food is known as Pica, a behavior condition associated with ...
