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 ...
On a hydraulic vehicle braking systems, the bleed screws (sometimes known as bleed nipples or bleeder valves) are located at the top of each brake caliper to allow bleeding of the braking system. Whenever service work has been performed on the braking system which might have introduced air into the system (i.e. the hydraulic system has been ...
Sea star wasting disease or starfish wasting syndrome is a disease of starfish and several other echinoderms that appears sporadically, causing mass mortality of those affected. [1] There are approximately 40 species of sea stars that have been affected by this disease.
Hemostats. A hemostat (also called a hemostatic clamp; arterial forceps; and pean, after Jules-Émile Péan) is a tool used to control bleeding during surgery. [1] Similar in design to both pliers and scissors, it is used to clamp exposed blood vessels shut.
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 ...
Choriaster granulatus is a large sea star with a convex body and five short arms. The arms have rounded tips, making it appear "phallic", leading to one of its common names being "the doughboy starfish". Relatively large in comparison with other sea stars, its maximum radius is about 27 centimetres (11 in).
Underside of a sunflower sea star. Sunflower sea stars can reach an arm span of 1 m (3.3 ft). They are the heaviest known sea star, weighing about 5 kg. [4] They are the second-biggest sea star in the world, second only to the little known deep water Midgardia xandaros, whose arm span is 134 cm (53 in) and whose body is 2.6 cm (roughly 1 inch) wide.

Sea Star was a supertanker from South Korea that spilled some 115,000 tons of crude oil into the Gulf of Oman on December 19, 1972, after colliding with the Brazilian tanker Horta Barbosa. After the collision both vessels caught fire and were abandoned by their crews. Twelve of the crew members died in the fire, which burned for five days.
