Corals vs. Sponges — What's the Difference?
By Tayyaba Rehman — Published on January 1, 2024
Corals are marine invertebrates forming large, colorful colonies with a hard skeleton, while sponges are simple, porous animals that filter feed, lacking true tissues or organs.

Key Differences
Corals are marine invertebrates known for their bright colors and hard calcium carbonate skeletons, forming coral reefs. Sponges, in contrast, are simpler organisms, often lacking distinct colors and shapes, with porous bodies and no skeleton.
Corals engage in a symbiotic relationship with algae, which live in their tissues and provide them with nutrients via photosynthesis. Sponges, however, filter feed by drawing water through their porous bodies, trapping nutrients.
The structure of coral reefs is created by the accumulation of coral skeletons, which form complex habitats for diverse marine life. Sponges do not build such structures but can be found growing on various surfaces in the ocean.
Corals are more sensitive to environmental changes, like ocean acidification and temperature shifts, which can lead to coral bleaching. Sponges are generally more resilient to environmental changes but can also be affected by pollution and habitat destruction.
