(2014) suggested conservation of the triclad
immune system, which may protect against infections, participate during regeneration, and promote wound repair.
We collected 22 taxa (10 species & 12 taxa identified to genus or family) of invertebrates, including one isopod, 1 decapod, 4 pelecypods, 1 gastropod, 1 leech, 1 annelid, I triclad
, 5 dipterans, 2 odonates, 2 coleopterans, 2 hemipterans, and 1 megalopteran.
Flow mediates predator-prey interactions between triclad
flatworms and larval black flies.
Some aspects of reproductive biology in the freshwater triclad
turbellarian Cura foremannii.
The phylogenetic trees inferred from comparisons of nucleotide sequences of 5S rRNA suggested that the dicyemids emerged first among the metazoa examined and that triclad
flatworms, nematodes, cnidarians, and sponges followed, in that order (Ohama et al., 1984, Hori and Osawa, 1987).
An embryonic digestive system, consisting of mouth, pharynx and intestine, which is involved in swallowing and digestion of the yolk, was described for several triclad
species (Curtis, 1902; Mattiesen, 1904; Fulinski, 1938; Le Moigne, 1963).
Results of such mechanisms or processes are especially frequent in triclads
(Kawakatsu et al., 1983, 1984).

Turbellarians can be divided into two major groups, with no taxonomical association: the macroturbellarians or large worms, which include triclads
and polyclads, and the microturbellarians including the other turbellarian groups, the members of which are smaller.
For example, some invertebrates are negatively phototaxic (e.g., triclads
; Thorp and Covich, 1991) and the crevices among zebra mussel shells would provide darker habitats.
