Oligophagy is a term for intermediate degrees of selectivity, referring to animals that eat a relatively small range of foods, either because of preference or necessity. [2] Another classification refers to the specific food animals specialize in eating, such as: Carnivore: the eating of animals Araneophagy: eating spiders; Avivore: eating birds
Like other Maratus spiders, the males of the species engage in a courtship display, during which they extend their median and posterior fringed spinnerets. A male presents both the extended spinnerets and his expanded and inflated opisthoma as he faces the female that he courts. [4] Females will usually mate only once.
The Goliath birdeater is native to the upland rainforest regions of Northern South America: Suriname, Guyana, French Guiana, northern Brazil, eastern Colombia, and southern Venezuela. Most noticeable in the Amazon rainforest, the spider is terrestrial, living in deep burrows, and is found commonly in marshy or swampy areas. It is a nocturnal ...
They are generally found in tropical rainforest and agricultural sites in Mexico, and their habitats tend to be highly productive (high generation rate of biomass). [1] Their group sizes are relatively larger than other colonial spiders, typically ranging from hundreds to thousands of individuals.
Although prey is usually consumed underwater in the diving bell, it is occasionally brought to the surface. A. aquatica is the only known species of spider that spends almost all its life underwater, including resting, catching and eating prey, mating, egg laying, and overwintering.
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
[4] The spider's web occupies a unique biological niche: "They build their web with the orb suspended directly above a river or the water body of a lake, a habitat that no other spider can use". [4] This position allows the spiders to catch prey flying over the water, with webs observed containing up to 32 mayflies at a time. [2]
Desert Spider, Stegodyphus lineatus, one of the best-described species that participates in matriphagy Matriphagy is the consumption of the mother by her offspring. [1] [2] The behavior generally takes place within the first few weeks of life and has been documented in some species of insects, nematode worms, pseudoscorpions, and other arachnids as well as in caecilian amphibians.
