Bugula neritina is a colonial animal that grows in upright, bushy, branching tufts, up to 15 cm or so in height, that are often mistaken for a seaweed. They are usually a dark red-purple or purple-brown, though occasionally they are a dull, dark red.

Bugula neritina is the only red or purple bryozoan on the Pacific Coast that grows in upright, bushy tufts. Other Pacific Coast species with this colony form, including several other Bugula species, are white or tan in color, usually have spines or bird's-head avicularia, and usually lack the conspicuous, globular ovicells that are characteristic of Bugula neritina. A beginning naturalist might be most likely to mistake Bugula neritina for a small red seaweed.

Watersipora subtorquata, commonly known as the red-rust bryozoan, is a species of colonial bryozoan in the family Watersiporidae. It is unclear from where it originated but it is now present in many warm-water coastal regions throughout the world, and has become invasive on the west coast of North America and in Australia and New Zealand.

Watersipora subtorquata is a type of colonial animal called a bryozoan. It grows on a variety of hard substrates including rocks, shells, docks, vessel hulls, pilings, debris, kelp holdfasts, and other bryozoans. On flat surfaces the smaller colonies, up to several centimeters in diameter, are flat and roughly circular. As a colony grows larger it becomes more lobed and may overgrow itself in places. In protected waters where growing conditions are good, colonies may become quite large and grow outward from the substrate (which is often the side of a dock) in lobes and frills, forming a striking, cauliflower-like mass up to 25 cm in height. It is typically a bright orange or red, with varying (sometimes large) amounts of black

This genus belongs to the phylum bryozoa. Each individual organism lives in its own case called an outer cuticle or exoskeleton. This outer cuticle protects the softer organism on the inside and has an opening through which the organism can extend its tentacles and feed.

This organism is a crunchy colonial organism
