Step 1: Drawing Duncan coral is simple. Start by making a small upright oval.
Step 2: Within the oval, draw a small crescent shape for the coral's mouth.
Step 3: Now draw the many tentacles of your coral by having curved lines come to sharp points. Be sure not to leave spaces between the base of the tentacles.
Step 4: The last step is to draw the wide polyp connected to the sides of the tentacles. Use two curved lines for this, bring the line on top slightly further down than the lower line.
Interesting Facts about the Duncan Coral
Duncan coral are commonly found growing in branched form or clusters in the rocky and stony sea surface of South China Sea and Australia. Their living conditions include salt water, 24 to 27 °C temperature and light for the process of photosynthesis to occur. These polyps are brown or green colored and are big, flat and wide disc-shaped with striped or colored design on them. They contain fairly thin tentacles, which have cells lined up in a row that have the ability to sting, used for self defense. These polyps have a diameter of about 2.5cm. They feed on phytoplankton and zooplankton.
Did you know?
- ‘Nematocysts’ is the term used to describe the stinging cells present on the tentacles, which releases a sticky substance upon touching.
- The basic unit of a coral is called a polyp.
- Polyps respond to external stimuli by either opening or closing themselves.
- The slimy outer covering of Duncan coral can irritate human skin and is toxic.
- They are commonly found in aquariums and are sold in several parts of the world.
Lesson plan note: Since corals have varying shapes, children can draw corals on a paper and paint the rest of the area around blue. They may also draw a few multi colored fish on the paper. You can then put all the corals together on the board to form hand-made coral reef!
