Replicated basal bodies act as or- ganizing centers for the mitotic spindle. Most symbiotic diplomonads form cysts at some point during their life cycle. Those that form cysts alternate between a motile trophozoite form and a dormant encysted form. Giardia intestinalis, for example, will form a thick protective cov- ering that resists desiccation as it passes from the host’s small intestine into the large intestine, where it is prone to dehydration Earthworm Ecology, Second download online

A few nerve cells and synapses are polarized (bipo- lar) and allow for transmission in only one direction, but most cnidarian neurons and synapses are nonpolar— that is, impulses can travel in either direction along the cell or across the synapse. Thus, sufficient stimulus sends an impulse spreading in every direction , cited: Illustrations of comparative download for free

There are a number of good articles available online for how to culture phytoplankton at home (e.g., Marini 2002, Toonen 1998a), but it is now so simple to buy phytoplankton to feed to a reef tank rather than growing your own that unless you’ve got a very large tank and are using a lot of phytoplankton, most people opt to simply buy it. If you’re a real do-it-yourselfer, then it is certainly possible and cheap to culture algae at home, but you have to do it correctly or the phytoplankton can not only be non-nutritious, under some improper culture conditions, it can be downright toxic (see, Toonen 1998a) Trends and Perspectives in download online

These are the so-called naked amebas (Figure 5.32A–D). Others, known as testate amebas, have the plasma membrane covered by some sort of test (Figure 5.32E,F). The tests of rhizopodans may be composed of particulate material either gathered from the environment (e.g., Difflugia) or secreted by the cell itself (e.g., Arcella). Some of the naked amebas (e.g., the genus Amoeba) may secrete a mucopolysaccharide layer, called the glycocalyx, on the outside of the plas- ma membrane download Giant Tube Worms and Other Interesting Invertebrates (Creatures of the Deep) pdf. On the other hand, the syncytial theory implies that the an- cestors of the cnidarians were triploblastic, acoelomate organisms, perhaps something like rhabdocoel turbellar- ians, that underwent “degenerative evolution” to pro- duce what we recognize today as the cnidarians. This view, sometimes called the turbellarian theory, holds the Anthozoa to be the most primitive cnidarian class and cites the “remnants” of bilateral symmetry in that class as evidence of a bilateral ancestry , cited: Invertebrate Surveys for Conservation

Eulamellibranch bivalves have a similar ctenidial de- sign, but neighboring filaments are actually fused to one another by tissue junctions at numerous points along their length, an arrangement resulting in interfilament pores that are rows of ostia rather than the long narrow slits of filibranchs (Figure 20.31B,E,F) , cited: Ladybugs

Development is thus mixed, with a long brooding phase and a short dispersal phase.
