Further infor- mation on the giant Gippsland earthworm Megascolides australis (McCoy 1878). Some zoologists, however, view these similarities as convergent features resulting from adaptations to pelagic lifestyles. The two main groups of animals are vertebrates and invertebrates. These vessels end abruptly where their contents move into the coelom or other large space where gas, nutrient, and waste exchange take place directly between the cells (tissues) and hemolymph (or lymph—at this point the fluid could be described as extracellular fluid).

Chemoreception is a rather direct sense in that the molecules stimulate sensory neurons by contact, usual- ly after diffusing in solution across a thin epithelial cov- ering. The chemoreceptors of many aquatic inverte- brates are located in pits or depressions, through which water may be circulated by ciliary action epub. In these cases sperm are picked up in the water currents of females and the eggs are retained in a brooding area, where they are fertilized. Argyrotheca, for example, broods its em- bryos in the enlarged nephridia. Others retain their em- bryos on the arms of the lophophore, in special regions of the mantle cavity, or in modified depressions in a valve , e.g. An Identification Guide to the Larval Marine Invertebrates of the Pacific Northwest download An Identification Guide to the Larval Marine Invertebrates of the Pacific Northwest pdf, azw (kindle), epub.

There are up to 200 gill slits, separated from one another by gill bars, which are supported by cartilaginous rods. The trapping of food from the inflowing water in- volves complex handling and sorting activities that ac- tually occur before water enters the mouth. The mouth is housed within a depression called the vestibule, which is formed by an anterior extension of the body called the oral hood (Figure 23.18A,B) ref.: Polychaetes: Interstitial Families - Keys and Notes for the Identification of British Species (Synopses of the British Fauna, New Series)

Most millipedes are slow-moving detritivores with a preference for dead and decaying plant material. They play an important role in the recycling of leaf litter in many parts of the world. Most bite off large pieces of vegetation with their powerful mandibles, mix it with saliva as they chew it, and then swallow it , cited: Atlas of Marine Zooplankton Straits of Magellan: Amphipods, Euphausiids, Mysids, Ostracods, and Chaetognaths
