Blade adaptations like these are how kelp have evolved for efficiency in structure in a turbulent ocean environment, to the point where their stability can shape entire habitats. Apart from these structural adaptations, the evolution of dispersal methods relating to structure have been important for the success of kelp as well.
Smaller areas of anchored kelp are called kelp beds. They are recognized as one of the most productive and dynamic ecosystems on Earth. [ 1 ] [ 2 ] Although algal kelp forest combined with coral reefs only cover 0.1% of Earth's total surface, they account for 0.9% of global primary productivity . [ 3 ]
The “kelp highway” hypothesis is a corollary to the coastal migration theory developed by Erlandson and his colleagues to help explain the peopling of the Americas and the presence of pre-Clovis sites such as Monte Verde and Oregon's Paisley Caves that date to ~14,000 years ago, before the ice-free corridor appears to have opened.

Egregia menziesii is a species of kelp known commonly as feather boa kelp. It is the only species in the monotypic genus Egregia . It is native to the coastline of western North America from Alaska to Baja California , where it is a common kelp of the intertidal zone .
A substantial die off of Durvillaea bull kelp occurred along the Kaikōura coastline following the 2016 Kaikōura earthquake, which caused uplift up to 6 metres. [17] [4] [43] [44] [45] The loss of Durvillaea kelp caused ecological disturbance, significantly affecting the biodiversity of the local intertidal community.
A nutrition pro highlights kelp's dietary health benefits, including essential nutrients and a potential metabolism boost. Plus, some tips for cooking kelp.
Ecklonia maxima, or sea bamboo, is a species of kelp native to the southern oceans. It is typically found along the southern Atlantic coast of Africa, from the very south of South Africa to northern Namibia. In these areas the species dominates the shallow, temperate water, reaching a depth of up to 8 metres (26 ft) in the offshore kelp forests ...
