Because this sea star is a top-level predator, its disappearance had profound effects on the ecosystem. [20] In the Channel Islands off the coast of California, ten species of sea star were recorded as being affected as well as three species of sea urchins, two brittle stars and a sea cucumber, all of which experienced large population declines ...
Brake bleeding is the procedure performed on hydraulic brake systems whereby the brake lines (the pipes and hoses containing the brake fluid) are purged of any air bubbles. This is necessary because, while the brake fluid is an incompressible liquid , air bubbles are compressible gas and their presence in the brake system greatly reduces the ...
Bump steer can become a problem when cars are modified by lowering or lifting, when a spring has become worn or broken causing a lower ride height, or if the vehicle is heavily loaded. When a car is lowered or lifted, the wheels' toe setting will change. When a car is lowered or lifted, it will have to be re-aligned to avoid excessive tire wear.

Exercise-induced pulmonary hemorrhage (EIPH), also known as "bleeding" or a "bleeding attack", is the presence of blood in the airways of the lung in association with exercise. EIPH is common in horses undertaking intense exercise, but it has also been reported in human athletes, racing camels and racing greyhounds .
Starfish, such as the ochre sea star (Pisaster ochraceus) and the reef sea star (Stichaster australis), have become widely known as examples of the keystone species concept in ecology. The tropical crown-of-thorns starfish ( Acanthaster planci ) is a voracious predator of coral throughout the Indo-Pacific region, and the Northern Pacific ...
Aboral surface of an Asterias forbesi sea star showing ring of pedicellariae surrounding spine. Asterias, like most starfish genera in the order Forcipulatida, are recognisable externally by their pedicellariae, many thousands of tiny jaw-like structures on the skin which can snap shut to nip at prey or predators.
