A dragonfly in its radical final moult, metamorphosing from an aquatic nymph to a winged adult.. In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is a process by which an animal casts off parts of its body to serve some beneficial purpose, either at specific times of the year, or at specific points in ...
At night organisms are in the top 100 metres of the water column, but during the day they move down to between 800 and 1000 meters. If organisms were to defecate at the surface it would take the fecal pellets days to reach the depth that they reach in a matter of hours.
In video games using procedural world generation, the map seed is a (relatively) short number or text string which is used to procedurally create the game world ("map"). "). This means that while the seed-unique generated map may be many megabytes in size (often generated incrementally and virtually unlimited in potential size), it is possible to reset to the unmodified map, or the unmodified ...
The spawn (eggs) of a clownfish. The black spots are the developing eyes. Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, to spawn refers to the process of freely releasing eggs and sperm into a body of water (fresh or marine); the physical act is known as spawning. The vast majority of aquatic and ...
Ark: Survival Evolved is an action-adventure survival game set in an open world environment with a dynamic day-night cycle and played either from a third-person or first-person perspective. To survive, players must establish a base, with a fire and weapons; additional activities, such as taming and feeding dinosaurs, require more resources. [4]
The earliest evidence of swarm behaviour in animals dates back about 480 million years. Fossils of the trilobite Ampyx priscus have been recently described as clustered in lines along the ocean floor. The animals were all mature adults, and were all facing the same direction as though they had formed a conga line or a peloton.
The colonization pathways of Theridion grallator through the eastern Hawaii islands. Oceanic dispersal is a type of biological dispersal that occurs when terrestrial organisms transfer from one land mass to another by way of a sea crossing.
Chum salmon is a typical cold water fish that prefer water around 10 °C (50 °F). When water temperature is raised due to thermal pollution, chum salmon tends to dive into deep water for thermoregulation. This reduces the time chum salmon spent in surface water column and reduce the chance for chum salmon to approach natal river since the ...
