Scientific name of the Crown of Thorns starfish
acanthaster planci
Crown of Thorns starfish are native to
coral eating starfish native to indo-pacific ocean
Crown of Thorns starfish are important because
important in coral reef, feeds on fastly growing coral to allow slow growing coral to grow more- control coral growth
low number of Crown of Thorns starfish can cause/
high number of Crown of Thorns starfish can cause
low number of starfish corals can recover naturally occur, high number of starfish and coral can’t recover (crown of thorns starfish outbreak)
Crown of Thorns starfish reaction to nutrients
increased nutrients= more starfish
larva use nutrients to grow big
Crown of Thorns starfish outbreaks
outbreaks caused by flood
what does Fleshy Algae do
fleshy algae or seaweed takes over less built coral reefs and destroys them
Fleshy Algae growth of pop
overfishing- less fish to feed on them
direct nutrient pollution
Fleshy Algae problems with over pop
less diverse
coral taken over by algae discs
Grouper >30cm scientific name
serranidae, epinephelinae
Grouper >30cm location
located west coast of Africa, southern Americas coast

Hard coral behavior
may look/ act like plants but are animals
colonial- group together
Hard coral relatives
closely related to jelly fish

clear water
access to sunlight
low nutrient levels
water temp range 16-35 ºc
how do Hard coral obtain energy
gain most of its energy from tiny algae called zooxanthelle (autotrophic) which live inside of them
coral provides safe place for algae to live in return they get energy
Hard coral difference from soft coral
hard coral has smooth tentacles and hard skeleton, soft corals have feathers and are squishy and spongy

shallow cervical groove (pinchers)
reef Lobster- human interference
popular in aquariums but capturing causes reduction in pop and destruction of coral reef
