Did you know not everything you see on a coral reef is actually coral?

Reefs are incredibly diverse ecosystems, filled with a wide variety of species that each play a role in keeping the system healthy. Sponges, for example, might look like coral at first glance—but they’re very different organisms. While corals build the reef’s hard structure, sponges act as natural filters, cycling water and nutrients through the ecosystem.

Being able to spot the difference helps us better understand just how complex—and interconnected—coral reefs really are.
