Mysterious Wasting Virus Killing Starfish Along West Coast
2013-11-04 15:04:27

Brett Smith for redOrbit.com - Your Universe Online California marine biologists are reporting the spread of a mysterious bacteria that is killing starfish up and down the West Coast – transforming the echinoderms into piles of goo in the process. “They essentially melt in front of you,” Pete Raimondi, a biologist at the University of California, Santa Cruz, told The Santa Rosa Press Democrat. The affected animals form white lesions on their exterior that grow and occasionally...

Mass Star Fish Die Off

Coral Reef Killer May Have A New Nemesis
2012-10-08 14:15:00

Alan McStravick for redOrbit.com - Your Universe Online The farmer and the casual gardener know the damage that can be done by an outside pest. Through chemical and organic (for the more eco-conscious among them) pesticides, they are able to eradicate the small predators that threaten their ecosystem. But just how do you effectively clear out a pest when its attack is underwater? This week, a team of marine scientists from James Cook University´s (JCU) ARC Centre of Excellence for...

Atlantic Ocean Gets Hit With Invasive Brittle Star Species

redOrbit Staff & Wire Reports - Your Universe Online The appearance and ecology of Atlantic coral reef habitats could be altered by yellow brittle star A study co-written by Dr. Gordon Hendler of the Natural History Museum of Los Angeles County (NHM) about an invasive species of brittle star, Ophiothela mirabilis, has been published online in Coral Reefs, the Journal of the International Society for Reef Studies. Growing populations have established themselves at distant points in...

One of the greatest biological threats to tropical coral reefs can be a population outbreak of crown-of-thorns (COT) sea stars (Acanthaster planci). Outbreaks can consume live corals over large areas, a change that can promote algal growth, alter reef fish populations, and reduce the aesthetic value of coral reefs, which in turn negatively affects tourism. Despite more than 30 years of research, the triggers and spread of COT outbreaks are not fully understood. Human impacts such as...

Scientists have discovered that one species of starfish has a remarkable strategy to avoid overheating in the sun, BBC News reported. Experts say the ochre starfish or sea star (Pisaster ochraceus) pumps itself up with cold seawater to lower its body temperature when exposed to the sun at low tide, something scientists say is equivalent to a person drinking seven liters of water before heading into the midday sun. But the researchers warn that global climate change may drastically interfere...

Canadian zoologists have determined elevated water temperatures and high carbon dioxide concentrations can boost the growth of a species of sea star. The University of British Columbia scientists said their study is one of the first to look at the impact of ocean acidification on marine invertebrates that don't have a large calcified skeleton or external shell. The researchers said their findings challenge current assumptions about the potential impact of climate change on marine species. The...

New research by UBC zoologists indicates that elevated water temperatures and heightened concentrations of carbon dioxide can dramatically increase the growth rate of a keystone species of sea star. The study is one of the first to look at the impact of ocean acidification on marine invertebrates that don't have a large calcified skeleton or external shell, and challenges current assumptions about the potential impact of climate change on marine species. The findings were published online...

It can be found in the North Sea and the Atlantic Ocean with a range that includes coastlines of Greenland, Canada, and the United States. It prefers a habitat in areas with adequate to heavy shelter and muddy or rocky sediment, at depths of up to 1,480 feet. The northern sun star is large, reaching a diameter of 7.9...

The horned sea star (Protoreaster nodosus), also known as the chocolate chip sea star, is a species of starfish that is classified within the Oreasteridae family. It can be found in the Indo-Pacific region and prefers a habitat within hidden sandy or muddy areas, with substrate such as coral, but can be seen in sea grasses. This species can reach an average diameter of 11.8 inches with four to six arms, although it is more common to see star-shaped individuals with five arms. It is...

The crown-of-thorns starfish (Acanthaster planci) is a species of starfish that is classified within the Acanthasteridae family. This species has a large range that extends from the Red Sea to the African coasts in the east and from the Indian Ocean to the western coasts of Central America. It prefers a habitat in coral reefs, which can be harmed if population numbers are too high. Damage occurs when filamentous algae covers bare skeletons of coral and the starfish move in to feed, stripping...

The New Zealand common cushion star (Patiriella regularis) is a species of starfish that is classified within the Asterinidae family. It is native to New Zealand waters, but has been introduced into Tasmania, where it is thought by some to be an invasive species. Studies of this species have shown that individuals occurring in the north of its range vary from individuals in southern waters, which hold slightly different environments.
