| The medically important flatworms are further divided into the flukes and tapeworms. |
|
| The cestodes, or tapeworms, differ in a number of ways from other flatworms. |
|
| Figure 1 presents the results for the schistosomes, and differences between these and other parasitic flatworms are given below. |
|
| Mitogenic rays, the midwife toad, and the flatworms that acquired memories through cannibalism share a chapter. |
|
| The simplest animals that are bilaterally symmetrical and triploblastic are the Platyhelminthes, the flatworms. |
|
| The larvae of flatworms burrowing into your skin cause this nasty little disease! |
|
| In some flatworms, the process of cephalization has included the development in the head region of light-sensitive organs called ocelli. |
|
| Feeding flatworms extend a long pharynx out of their mouths. This tube leads directly into the digestive tract. |
|
| The planarians used in these studies, also called flatworms, live in fresh water and have a singular ability to regenerate. |
|
| Among the earliest hunters, flatworms were simple but effective killing machines. |
|
| Planarians are free-living flatworms, and have a much simpler life history. |
|
| The initial studies involved little flatworms called planaria that have a very primitive nervous system. |
|
| They include such things as spiders, leeches, millipedes, pill bugs, flatworms, mites, beetles, and water dwellers such as water scorpions and nematode worms. |
|
| Of course, philosophically speaking, where humans differ from other species is that they are self-conscious, in a way that albatrosses and flatworms just don't seem to be. |
|
| The organization of the body compartment between the epidermis and gut in nemerteans and flatworms also does not reveal a uniquely similar pattern. |
|
| For example, bacterial endosymbionts as found in the giant vent Pogonophora are also present in many meiofaunal oligochaetes, nematodes and flatworms. |
|
| The larvae of some sea anemones are parasites on ctenophores, as are the larvae of some flatworms that parasitize fish when they reach adulthood. |
|
| Juveniles of Soleichthys maculosus mimic toxic flatworms of the genus Pseudobiceros in both colours and swimming mode. |
|
| The flatworms known as planaria have long amazed scientists with their capacity for regeneration. |
|
| Responses to magnetic fields by homing pigeons, fruit flies and flatworms also are apparently affected by lunar phase. |
|
|
|
| Like nematodes, flatworms are some of the most diverse and commonly reported endoparasites of domestic animals. |
|
| Planarians are turbellarian flatworms widely used in experimental biology. |
|
| They are now classified into over 30 phyla, from simple organisms such as sea sponges and flatworms to complex animals such as arthropods and molluscs. |
|
| Even amongst planarian flatworms, famous for their ability to regenerate from random tissue fragments, species exist that have completely lost the ability to regenerate. |
|
| A new biological study will use flatworms as a model organism to see how gravity affects tissue regeneration and the rebuilding of damaged organs and nerves. |
|
| Flatworms are unsegmented, bilaterally symmetrical worms that lack a coelom but that do have three germ layers. |
|
| Flatworms are acoelomates, lacking a body cavity, as are their closest relatives, the microscopic Gastrotricha. |
