The arthropods are a phylum of animals with jointed legs; they include the insects, arachnids such as spiders, myriapods, and crustaceans. [1] Insects play many roles in culture including their direct use as food, [2] in medicine, [3] for dyestuffs, [4] and in science, where the common fruit fly Drosophila melanogaster serves as a model organism for work in genetics and developmental biology.
The intentional cultivation of insects and edible arthropods for human food is now emerging in animal husbandry as an ecologically sound concept. Several analyses have found insect farming to be a more environmentally friendly alternative to traditional animal livestocking.
The eggs, larvae, pupae, and adults of certain insects have been eaten by humans from prehistoric times to the present day. [8] Around 3,000 ethnic groups practice entomophagy. [9] Human insect-eating (anthropo-entomophagy) is common to cultures in most parts of the world, including Central and South America, Africa, Asia, Australia, and New ...
Extant marine arthropods range in size from the microscopic crustacean Stygotantulus to the Japanese spider crab. Arthropods' primary internal cavity is a hemocoel, which accommodates their internal organs, and through which their haemolymph - analogue of blood - circulates; they have open circulatory systems. Like their exteriors, the internal ...
They fill essential roles as decomposers and food sources for lower trophic levels, and are necessary to drive processes within larger organisms. Populations of microfauna can reach up to ~10 7 (~10,000,000) individuals per g −1 (0.1g, or 1/10th of a gram) and are very common in plant litter, surface soils, and water films. [ 3 ]
Scientists have solved a long-standing mystery about how the extinct arthropod Odaraia alata snipped, gripped and ripped its way to ancient survival. Ancient swimming ‘taco’ had ‘bug jaws ...
The "Spanish fly", Lytta vesicatoria, has been considered to have medicinal, aphrodisiac, and other properties. Human interactions with insects include both a wide variety of uses, whether practical such as for food, textiles, and dyestuffs, or symbolic, as in art, music, and literature, and negative interactions including damage to crops and extensive efforts to control insect pests.
When you watch the video you can see the octopus discovers the fish inside the bottle but can’t get it out. It steps back for a few minutes, considering the problem. Then, the octopus returns to ...
