Crown-of-thorns starfish (Acanthaster planci)

The crown-of-thorns seastar is a large starfish that preys upon hard, or stony, coral polyps (Scleractinia). The crown-of-thorns starfish receives its name from venomous thorn-like spines that cover its upper surface, resembling the biblical crown of thorns. It is one of the largest starfish in the world. A. planci has a very wide Indo-Pacific distribution. It is perhaps most common in Australia, but can occur at tropical and subtropical latitudes from the Red Sea and the east African coast across the Indian Ocean, and across the Pacific Ocean to the west coast of Central America. It occurs where coral reefs or hard coral communities occur in this region. The body form of the crown-of-thorns starfish is fundamentally the same as that of a typical starfish, with a central disk and radiating arms. Its special traits, however, include being disc-shaped, multiple-armed, flexible, prehensile, and heavily spined, and having a large ratio of stomach surface to body mass. Adult crown-of-thorns starfish normally range in size from 25 to 35 cm. They have up to 23 arms.They are usually of subdued colours, pale brown to grey-green, but they may be garish with bright warning colours in some parts of their wide range.

Lo sviluppo del robot automatico per uccidere la stella corona di spine va avanti

Lo sviluppo del robot automatico per uccidere la stella corona di spine va avanti - Lo sviluppo di questo robot automatico, il RangerBot, va avanti e presto potremmo averne diversi che in autonomia ricerchino le stelle corona di spine e le uccidano senza arrecare danno alla barriera corallina ed ai suoi abitanti.
