Problem:
-eating the living coral
Solution:
-End over fishing (first)
-injecting a type of salt into crowned starfish

# data[].attributes.body
Solution: humans stop over fishing

# data[].attributes.body
Problem: starfish are able to hurt several diver

# data[].attributes.body
The thorny starfish surpassed in size  by the sunflower starfish

SALUTION

# data[].attributes.body
the people injected something into the starfish that kills it but not the coral reef

# data[].attributes.body
(Problem)
Starfish are eating the polyps which affects the coral reef.
(Solution)
They could either spray something on the coral to make the starfish stop eating it or spray something on the starfish so they lose their appetite for coral.

# data[].attributes.body
the starfish could injure divers several

Problem, The starfish destroys the reefs and then keeps multiplying.

Solution, they are using sodium bisulphate. and kill

# data[].attributes.body
the crown of thorn starfish keeps eating coral reefs

# data[].attributes.body
one problem is a some starfish are dying

# data[].attributes.body
they have venom thorns

# data[].attributes.body
a single crown of thorns starfish can devour as much as six square meters

They can survive months without food and sill reproduce themselves

# data[].attributes.body
THESE animals are endemic native to the tropical coral reefs throughout the Pacific ocean, the Indian ocean and the red sea.

a crown of thorns starfish can consume as much as six meters of living reef square.

# data[].attributes.body
problem: these starfish are a poisonous threat, meaning that they can injure divers, and damage their wet suits ( puncturing them, letting water get into them)
solution:  people have tried to kill them themselves with a dive knife or a drill bit, and other items
They can consume at least six square meters of living reef

# data[].attributes.body
Crown of Thorns Starfish are animals that feed on healthy coral reef. They release enzymes that liquefy the coral, making it easy for them to devour. People can start fishing less, and injecting some of them with sodium bisulphate, which will kill them, but will not harm the coral reef.

# data[].attributes.body
Crown of thorns starfish used to not have much threat but as the population expands the threat grows bigger and bigger

# data[].attributes.body
(Problem) The spikes on the thorn starfish can pierce a wetsuit or injur divers

(Soulution) You can inject sodium bisulphate, which kills them but does not hurt the coral reef

# data[].attributes.body
(problem) they are toxic one of the biggest threats  health and they are very spiny and there population is exploding

# data[].attributes.body
(Problem)
The thorn starfish are damaging healthy reefs by feeding on coral polyps.
(Solution) They can inject the thorn starfish with sodium bisulphate which kills the starfish, but leaving the coral reef unharmed.

# data[].attributes.body
1.These solitary animals are endemic -native-  to tropical coral reefs throughout the Pacific Ocean, the Indian Ocean, and the Red Sea.

2.A single crown of thorns starfish can consume as much as six square meters of living reef annually

Problem: The problem of this is that Crown of Thorns Starfish keep eating healthy reefs||||. Solution: The solution is to stop over-fishing because these starfish begin as plankton and whales eat plankton. If we don't stop over-fishing, then we will keep catching and killing whales, so Crown Of Thorns Starfish will keep booming in population, and the coral will die, and that could affect us||| Solution: We could inject the starfish with sodium bisulfate, and it will only hurt, and kill the starfish.

-Problem: this starfish are eating polyps and doing so kills coral
-Problem: people are trying to save the sea's from this starfish invitations
-Solution:people have begun attacking the starfish themselves

# data[].attributes.body
the starfish are eating the polyps and that kills the coral
the spines poke holes in wet suits
when the starfish eat they push out a poisons gas
people have began attacking the starfish and they are putting sodem in them and it kills them and doesn't hurt the coral

# data[].attributes.body
Throned starfish are booming in population Some solutions are to inject them with sodium witch defectively kills them without harming sea coral.

While our reefs are subject to human threats on an almost daily basis in most places, they are also under threat by some natural competitors, diseases, and predators, all of which seem to have been made worse by humanity's actions as a whole. One of the biggest threats to healthy reefs is the crown of thorns starfish, a spiny, toxic animal that feeds on living coral polyps.

Why the Crown of Thorns Starfish is a Threat

Before overfishing and global warming was a problem, crown of thorn starfish posed little, if any threat to marine environments. Today, their population is exploding.

Large, nocturnal sea stars that prey upon living coral, these solitary animals are endemic to tropical coral reefs throughout the Pacific Ocean, the Indian Ocean, and the Red Sea. The second largest of all the world's sea star species, surpassed in size only by the harmless sunflower starfish, the crown of thorns starfish gets its name from the thorny looking venomous spikes that cover its body, giving it as much appeal as an underwater cactus might have. Capable of piercing wetsuits and injuring divers, these starfish release chemicals when they feed, which attract additional crown of thorns stars to healthy reef sections, where they begin their destructive feeding frenzies, extruding their stomachs, which contain digestive enzymes, onto the reef, liquefying the coral tissue.

A single crown of thorns starfish can consume as much as six square meters of living reef annually; and, as they have only a few natural predators, they continue to breed and thrive, especially in areas where predators such as humphead wrasse and other large reef fish capable of taking on full grown specimens have had their populations decimated by overfishing.

What Can Be Done to Slow or Halt Crown of Thorns Starfish Invasions

Now, it is up to humanity to work to save reefs from crown of thorns starfish invasions. It all begins with ending overfishing, and bringing marine life numbers back up to where they were prior to the days when commercial fishing operations began in earnest. This is due to the fact that crown of thorn stars begin their lives as plankton; being fed upon by whales and other filter feeders. As they grow, they are subject to predation by fish and other animals that consume smaller organisms.

Until predatory species are brought back to health, people have begun attacking the starfish themselves, sometimes hacking them to bits with dive knives (not a good strategy, as they are capable of regenerating), and sometimes burying them beneath heaps of rubble, which is still not the best solution, since they can live for months without food and are still capable of reproducing.

One of the newest, most promising techniques for killing off crown of thorns starfish is to inject them with a solution of sodium bisulphate, which kills the sea star, but does not harm the coral reef.

Like other animals that have caused problems when populations explode, crown of thorns starfish do have a place in the environment; in fact, in a healthy environment, they prevent the fastest growing corals to take over slower growing species, keeping biodiversity high and enriching the environment. Until reefs and other animals are brought back to a state of health however, population control is a must. If they're a problem where you dive, look into volunteering with a control team. By sharing just a little of your time, you really can make a big difference.
