Enteromorpha intestinalis 50.470 (Linnaeus) Link.
Ulva intestinalis Linnaeus. Also known as Enteromorpha intestinalis Description: Inflated, hollow fronds with a bright grass-green colour, strongly resembling the large instestines of mammals. Habitat: Rock pools in the upper intertidal and salt-marshes, particularly in places where Distribution: Common through Britain and Ireland.Wildscreen's Arkive project was launched in 2003 and grew to become the world's biggest encyclopaedia of life on Earth. With the help of over 7,000 of the world’s best wildlife filmmakers and photographers, conservationists and scientists, Arkive.org featured multi-media fact-files for more than 16,000 endangered species.After conducting a phylogenetic DNA analysis, Hayden et al. (2003) found that the separation of the two genera was artificial and that species in Enteromorpha should be returned to the original Ulva classification. While ITIS lists U. flexuosa under the genus Enteromorpha, Enteromorpha species are now recognized as belonging to the genus Ulva.
Enteromorpha tolerates a wide range of salinities from 17 ppt. to 40 ppt. and is often found at the base of rivers and brackish water estuaries. Like other species of Ulva, it prefers cooler water temperatures in the aquarium and will not do well in temps over 80 degrees. Like other varieties, its very palatable to fish.A common green alga near the top of the shore, on rocks or other algae, on open coasts or in estuaries and harbours, where it may grow mixed with U. intestinalis or other species of the genus. It is better known as Enteromorpha prolifera, but Enteromorpha is now considered to be part of the genus Ulva (Maggs et al., in Brodie et al, 2007).
Gutweed is able to survive a wide range of salt concentrations. Other facts: There are about 10 different types of Gutweed, and it can be very difficult to spot the differences between them. Classification: Gutweed is a member of the protoctista group green algae.
