As many as 9000 species of algae are spread across the worlds oceans, some can be as much as 30 metres across while others are just a slippery scum over rocks.
Algae grows wherever there is enough light and life supporting conditions.
They support a huge number of marine life both for food and as a home. Ref: https://www.algaebase.org/search/species/detail/?species_id=71770
