Sessile benthic forms are rare (but see Figure 8.1F). These videos are not from a Christian perspective, so they do mention evolutionary ideas and include humans as animals. Several species of gutless marine oligochaetes have been described in shallow coral-sand habitats and in anaerobic, sulfide-rich subsurface sediments. Both tissues are ciliated, and their cilia produce currents in both the coelomic fluid and the overlying water.

Epidermis partly cellular, partly syncitial 6. Note the separation of air spaces and blood-filled leaves. If we start with a generalized, rather homono- mous arthropod prototype with a fairly high number of segments, and with paired appendages on each of those segments, we can set the stage for just such a dramatic diversification. This behavior is apparently triggered by winter storm fronts moving into the area, and it may be a means of avoiding rough water conditions in the shallows.

Particles in the 0.1 to 1.5 µm range (e.g., bacteria, large free organic molecules) are trapped in the mucous retic- ulum between the collar villi. In members of the family Amphinomidae, the nuchal organs are elaborate out- growths of an extension of the prostomium called the caruncle. Wilkinson (1983) showed that 6 of the 10 most common sponge species on the forereef slope of Davies Reef (Great Barrier Reef) are actually net primary producers, with three times more oxygen produced by photosyn- thesis (by their symbionts) than consumed by respira- tion.

In mosquitoes the saliva carries blood thinners and antico- agulants (and often parasites such as Plasmodium, which causes malaria). Perform a play about mammals, experience how blubber keeps marine mammals warm, sniff out your “baby,” examine animal skulls, dissect an owl pellet and piece together a rodent skeleton, and more! Ultrastructure and phylogeny of crustacean spermatozoa. This means that they use their body as a filter to trap their food, microscopic plankton.

Members of these groups carry their young in some sort of sac near the fe- male gonopore. Toward the end of the nineteenth century, Henry McCook sug- gested that silk may have evolved before the origin of spi- ders in vermiform terrestrial arthropods with multiple ex- cretory structures, such as coxal glands, opening near the bases of walking limbs. The porocyte extends all the way through the pinacoderm, the thin mesohyl, and the choanoderm into the atrium, emerging between adjacent choanocytes (Figures 6.4B and 6.7C).
