description Pelagophycus porra Overview
Pelagophycus porra, commonly known as elk kelp, is a large brown macroalga native to the deep marine waters of the Pacific coast of North America, specifically around California's Channel Islands. The species was taxonomically described by William Albert Setchell and Nathaniel Lyon Gardner in 1925. It is distinguished from other giant kelps by its large, antler-shaped pneumatocysts, which are gas-filled bladders that keep the plant's fronds afloat. The algae grow vertically from the ocean floor, providing physical structure and habitat for local marine life within its endemic range.

How can Pelagophycus porra be identified?
Elk kelp has long stipes, several narrow fronds, and buoyant spherical pneumatocysts. The antler-like branching is a useful field clue when identifying it underwater.
Is elk kelp part of the giant kelp forest?
