☻ Corals are Invertebrates☻ They are in the same family as jelly fish, sea anemones, and hydra☻ They are made of carnivorous animals called polyps☻ All kinds of fish live in corals
☻ There are two kinds:1. A fringing reef (a reef where coral polyps settle and grow close to the shore2. A barrier reef (if the land sinks or the sea rises, a polyp it makes a barrier reef☻ Smooth coral grows in rougher waters☻ Hard coral grows in calmer waters
☻ Corals are classified as Phylum Cnidarians☻ Corals fall into the vertebrate family☻ Although corals do live in the ocean they are not in the same family as fish
☻ Corals evolved into reef building forms over the last 20-25 million years☻ Coral beads and artifacts were discovered in Egyptian graves dating back as far as 4000 B.C.☻ They are also found in the graves from Iron Age and Neolithic sepulchers from 10,000 B.C.
The main kind of pollution killing corals is chemical pollution when harmful gases get into the air it gets in the ocean Littering kills them too so when you litter some trash companies dump it into the ocean Mud from runoff can smother the coral and they can’t breathe
Sharks are the most well known predators of the ocean, sea, and the coral reef Sharks that are dangerous to reefs: The sand tiger shark White tip reef shark Grey tip reef shark Black tip shark Silver tip shark
☻ Clown Fish☻ Giant Clam☻ Giant Cone Snail☻ All kinds of Octopi
☻ Corals are considered animals☻ Coral require sunlight and that’s why they like (warm) and shallow water☻ The Great Barrier Reef off the coast of Queensland, Australia is so big (apx. 2,000 kilo) that it can be seen from space☻ This is the brain coral that grows1-3 inches a year
☻ The mouth of a coral is surrounded by stinging tentacles☻ This is dynamite fishing which kills coral
