Unlike most fish, the Asian arowana reaches sexual maturity relatively late, after 3–4 yr. The females produce few eggs, 30–100, which are quite large. After the eggs are fertilized, the Asian arowana exhibits great parental care with paternal mouthbrooding. Both the fertilized eggs and larvae are brooded within the male's mouth. [5] [18]
Adult fish also prey on fish eggs and larvae. For example, haddock were observed satiating themselves with herring eggs back in 1922. [14] Another study found cod in a herring spawning area with 20,000 herring eggs in their stomachs, and concluded that they could prey on half of the total egg production. [17] Fish also cannibalise their own eggs.
The other is Hemerocallis fulva, the familiar tawny-orange daylily, also known affectionately as the "ditch lily". [12] The daylily has been nicknamed "the perfect perennial" by gardeners, due to its brilliant colors, ability to tolerate drought and frost and to thrive in many different climate zones, and for being generally low maintenance.
The Ichthyophiidae are the family of Asiatic tailed caecilians or fish caecilians found in South and Southeast Asia as well as southernmost China. [1] They are primitive caecilians, lacking many of the derived characters found in the other families. For example, their mouths are not recessed underneath their heads, they possess tails, and they ...
The scent of the plant is often described as 'foetid' due to the presence of trimethylamine which often gives off a rotting fish smell. [5] Mercurialine is thought to be one of the active principal parts that are responsible for the toxicity of the herb. [7] It is known to induce hemorrhagic inflammation of the gastrointestinal tract and kidneys.
Females may spawn two to three times per year, and produce between 80,000 and 1,000,000 eggs per event. In waters at 28 °C/83 °F, mahi-mahi larvae are found year-round, with greater numbers detected in spring and fall. [8] Mahi-mahi fish are mostly found in the surface water.
Caniformia is a suborder within the order Carnivora consisting of "dog-like" carnivorans. They include dogs (wolves, foxes, etc.), bears, raccoons, and mustelids. [1] The Pinnipedia (seals, walruses and sea lions) are also assigned to this group.
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.
