Many protozoa are motile, using pseudopoda, cilia, or flagella to move. Some cause diseases in larger organisms. The class <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVil55wpEbGdrcN5Y29ycA" class="cyc_term">Protozoan</a> is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViYV5wpEbGdrcN5Y29ycA" class="cyc_term">BiologicalSubkingdom</a> in many classification systems, sometimes placed under the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVimKZwpEbGdrcN5Y29ycA" class="cyc_term">ProtistaKingdom</a>.

Moreover, each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWXYgJwpEbGdrcN5Y29ycA" class="cyc_term">ExistingObjectType</a> is a collection that is temporally stuff-like (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a>) but physically-spatially object-like (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a>) -- i.e. object-like with respect to some physical-spatial part-whole predicate (e.g. some specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r8a2smPXcQdiEoJhcx65EiQ" class="cyc_term">properPhysicalDecompositions</a>).

Further, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a> is temporally stuff-like: any one of the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> of a given copy <code>COPY</code> of (say) "Moby Dick" is still a copy of "Moby Dick". (Most collections of tangible objects are temporally stuff-like in this way.) But <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a> is spatially object-like: if we take a scalpel and slice <code>COPY</code> into ten pieces, each piece is not a copy of "Moby Dick".
