Aquascope Facts
Cliff and rocky beach ecology There are several ways in which different organisms coexist with algae. There are those that just creep around on the algae; others attach themselves and live on or in the algae; some find it pleasant amongst the cavities in the holdfast; while some live in the sediment that collects around the lower parts of the algae. Variety amongst the kelp
The sugar kelps holdfast is an important environment for many organisms to live in.

Favorite substrate

Colony building sea-mats, hydroids, sea squirts and thread-like algae are examples of organisms that often cover large areas of the algaes older parts. Some of these organisms grow only on a specific species and even on only certain parts. The spiral building tubeworm Spirorbis corallinae is found almost entirely on coral algae. In this situation, the worm only uses the algae as a foundation from which it can collect food from the surrounding water.
