in length. Lots of bipyramidal crystals in cytoplasm. Uroid bulbous can
have adhesive filaments.(Bovee, 1972)
Trichamoeba gumia (Schaeffer,
1926) from W.N. Atlantic ocean 60-140um
Trichamoeba hirta The
type species of the genus up to 125um in
length but is probably not identifiable (Page,
Trichamoeba limax up
to 100mm. (Jahn
& Jahn, 1949). The status of this
species is uncertain as it was only partially described.
Trichamoeba myakka Characterized
by having a permanent hyaline often papillate uroid 200-300um
Trichamoeba osseosaccus (Schaeffer,
1926) is 100-150um.
is 60um in length but sometimes spreads flat
on surface. Isolated from the Gulf of Mexico.
Trichamoeba schaefferi (Radir,
in length (making it the largest described Trichamoeba). Many
bipyramidal crystals in cytoplasm. No floating form seen. See
above for the description of the E.M. findings (Siemensma
& Page, 1986).
is 20-30um. Isolated from the Gulf of Mexico.
Trichamoeba villosa. Famous
(amongst people who cared about these things at the time) for producing
stunning electron micrographs of cortically associated myosin
minifilaments supporting the general contraction theory of cell
locomotion (Bhowmick, 1967).
Although T. villosa being occasionally polypodal, cannot be
considered a member of the Trichamoeba genus, but may be a
member of the genus Amoeba instead (Siemensma
& Page, 1986; Page, 1988).
