Plants are important in the underwater world around Scilly. Seagrass is unusual because it is a type of flowering plant which can reproduce underwater – it has waterproof pollen!
Most other marine plants are much more primitive, these are the algae. Algae have no roots; instead they attach themselves to rocks or other algae or animals using a holdfast. In the clear waters of Scilly, algae can grow at a depth of over 30m.
There are some rare species of algae in Scilly including a type of kelp which normally lives further south. Kelp forests provide a three dimensional habitat for many species of fish and invertebrates.
