Coralline algae

[Mr31415]

This algae is quite unique as its cell walls actually contains calcareous deposits, enabling this organism to actively help build reef structures.

Here are some photos. They are hard to photograph because they are thick and almost opaque. Also, they are very brittle so getting a sample is not easy.

and my favourite... Showing the calcareous cell walls clearly.

40x, POL, 23 image stack using Helicon Focus method A.
