Origin of species name
Adjective (Latin), relating to or found in the intestines (Guiry & Nic Dhonncha, 2002).
A recent molecular study suggested that the genus Enteromorpha is synonymous with the genus Ulva (Hayden et al., 2003). Species within the genus Ulva are difficult to identify. Identification is heavily reliant on cell detail and cell arrangement, in addition to gross morphology, but complicated by the fact that the morphology of a single species can vary in response to environmental conditions. For instance, Ulva intestinalis and Ulva compressa (as Enteromorpha) are two distinct, genetically divergent and reproductively isolated species (Blomster et al., 1998). They are, however, difficult to distinguish. The presence or absence of branching fronds was the most useful gross morphological characteristic distinguishing these two species (Ulva intestinalis being unbranched). But ambiguity exists because low salinity or salinity shock can induce branching in Ulva intestinalis. However, if environmental factors, such as salinity are taken into account, branching can be used to identify the great majority of thalli correctly (Blomster et al., 1998).

Ulva intestinalis is a green alga in the phylum Chlorophyta, of the genus Ulva (sea lettuce), also known by the common names gutweed and grass kelp. Until they were reclassified by genetic work completed in the early 2000s, the tubular members of the genus Ulva were in the genus Enteromorpha.
It can be found in Bering Sea near Alaska, Aleutian islands, Japan, Korea, Mexico, and Russia. Besides this, places it can be found in Israel, and in such European countries as Azores, Belgium, Denmark, Ireland, Norway, Poland, and in such seas as the Baltic and Mediterranean Sea.
The fronds of the species may be 10–30 centimetres (3.9–11.8 in) long and 6–18 millimetres (0.24–0.71 in) wide. They have rounded tips as well.
