Ulva intestinalis
Also called Gut Weed
Gutweed (Ulva intestinalis) is a green seaweed (alga) found in shallow coastal and brackish waters worldwide, not a land plant. It grows as hollow, tubular fronds that are usually attached to rocks or other hard surfaces.
Ulva intestinalis is a green alga in the family Ulvaceae, known by the common names sea lettuce, green bait weed, gutweed, and grass kelp. Until they were reclassified by genetic work completed in the early 2000s, the tubular members of the sea lettuce genus Ulva were placed in the genus Enteromorpha.
This species has a generally world-wide distribution. In the Pacific Ocean, it can be found in the Bering Sea near Alaska, the Aleutian Islands, Puget Sound, Japan, Korea, Mexico, the Philippines, and Russia, as well as New Zealand. In the Atlantic Ocean, its range includes the Azores, the Baltic Sea, the Mediterranean Sea, and northern European countries such as Ireland, Belgium, Denmark, Norway, and Poland.
