Turkish Washcloth

Brief Description

A marine red alga found in the intertidal zone, characterized by its thick, bumpy, carpet-like blades.

Characteristics

The seaweed has dark purple to blackish, thick, rubbery blades that are covered in small, nipple-like bumps (papillae) on the surface of the female gametophyte.

Habitat

Often found on rocks in the high to mid-intertidal zones of rocky shores.

When to Find It

Perennial; visible year-round but most easily seen during low tides.

Conservation Status

Common / N/A

Ecological Role

Provides a complex habitat and shelter for small marine invertebrates and is a food source for various mollusks.

Easily Confused With

Often confused with Turkish Towel (Chondracanthus exasperatus), which typically has much larger blades and grows deeper in the water.

Observation Tips

Look for it on barnacle-covered rocks at low tide in the Pacific Northwest; it often feels stiff and sandpaper-like when dry.

Interesting Facts

This species has a 'crustose' stage in its life cycle once thought to be a completely different species of red algae called Petrocelis.
