ENTEROMORPHA Link. 
This genus is closely related to Viva. The membrane has two layers of 
cells as in Viva , but the layers separate and the frond is therefore hollow. 
The individual cells are alike in the two genera, though a tendency to 
arrange themselves in longitudinal rows is more evident in Enteromorpha. 
Very occasionally the chlorophores are grouped in fours. The reproduc- 
tion is as in Viva.

The coarser species are E. intestinalis, unbranched and inflated, and 
E. compressa, more or less branched and flat. They vary greatly in 
diameter from 1 mm. to 20 mm. or more, and also in height. They grow 
socially in tufts and in great numbers. They are largely used as a fish 
bait, especially for mullet. Ships coming into dock after long voyages 
have usually to be cleaned from a heavy growth of Enteromorpha, and 
thus the plant may be widely distributed. 
The finer, filiform species are E. crinita and E. clathrata. if indeed these 
are worthy’ of distinction. Harvey calls the plant sent to him by Mueller 
from the Lefevre Peninsula E. dathrata, “a most variable” species, of
