Advances in Parasitology APL
Monozoic adults had a full complement of male and female reproductive organs
but unlike polyzoic forms insemination had not taken place and eggs remained
unfertilized and did not embryonate. Many questions regarding the process of ...
W. H. R. Lumsden, R. Muller, James R. Baker, 1981
But his not made plain why we may not suppose that the ancestral forms of
various stocks passed through an imperfectly integrated colonial or polyzoic
stage. The author takes a survey of the animal kingdom, and seeks to
substantiate a ...

He suggested that protocestodes originally lived in a freshwater environment and
colonized the sea later. He also suggested that preand protocestodes may have
existed as monozoic and polyzoic forms, ie. strobilization may have been ...

Foundations of Parasitology: Ninth Edition
Cestodes with multiple proglottids are described as polyzoic, but of Eucestoda
members of order Caryophyllidea have only one genitalium and so are monozoic
(see Fig. 21.11). Some workers advise avoiding use of the terms polyzoic and ...
Larry Roberts, John Janovy, Jr., Steve Nadler, 2012
Eucestodes are thus said to be polyzoic. In contrast, Cestodaria lack a distinct
scolex and proglottisation, and are monozoic, possessing only a single set of
male and female reproductive organs per individual. The marine environment
figures ...
Various intermediate forms exist among both the monozoic and polyzoic
flatworms. The nervous system may be in the form of a primitive epidermal net, as
in a few free-living forms. However, most parasitic species possess relatively ...
