What different shapes are corals?

The reef is full of different shapes and sizes of coral. Some are look like branching trees, others like brains plopped on the bottom of the sea. If you went diving off American Samoa, you might even see one of the biggest coral colonies in the world, ‘Big Momma’.

Discover the different shapes that coral can take using Coral Reef Zones activity and think about some of the different factors that may influence their shape.

The live lesson will focus on reviewing this activity and looking at the different shapes that coral takes. There is also the whole world of twilight zone or mesophotic coral to think about as well and we have linked these additional activities to the lesson, Exploring deep coral and Depth and light.

Broadcast on Wed 8 Apr 2020
  • 30 mins
  • Ages 7-11, Ages 11-14

The live lesson assumes that students and families will have completed the Coral Reef Zone activity.

Don’t worry too much about creating the full underwater landscape in a box. Focus on making the different coral shapes using modelling clay or play dough. You can always make a poster of the coral reef zones using the diagram in the gallery as the background for your models.
