Coral Bridges

Coral Bridges are a species of large and rapidly-growing coral. They are found exclusively within the Twisty Bridges areas and are covered by Blue Barnacles.

Description
The bridges are very large and bulky, with a thick grey top side and a black underside. They grow out from canyon walls and continue growing, twisting and turning as they go until they meet another wall which they then attach to. The undersides of the bridges are always entirely covered by Blue Barnacles, which appear to be a separate species taking advantage of the bridges.

One data bank entry mentions that the bridges are so fast-growing that they make it difficult to map out a permanent route to Sanctuary Zero due to the constantly changing environment.

Some specimens can grow to be extremely large, as shown by one particular bridge found in the Deep Twisty Bridges that measures well-over 250 meters in length.
