*Before looking at the characteristics of Deltaproteobacteria, it's worth noting that some of the members have been re-classified (e.g. the order Bdellovibrionales now belongs to the class Oligoflexia). Moreover, there have been proposals to disassemble and re-classify most of the families wi...
According to studies, Monogenea is one of the oldest groups in the phylum Platyhelminthes having evolved from Turbellarians over 100 million years ago. While many of the species in the group share a number of morphological characteristics, such as a flattened body and being small in size, ...
Morphological characteristics of the soft-sediment clasts, and their facies context, provide evidence for transport mechanisms, depositional environment, and processes of clast deformation. The soft-sediment clasts were transported into a proglacial water body by unidirectional water currents (1.5鈥 2.5 m...
This paper describes various morphological features of continental shelf and their present-day analogues both present in surface and subsurface data. Most of the examples are taken from Pakistan Offshore. Identification of subsurface features from wireline logs and seismic data is very significant for ...
Each level is further subdivided based upon characteristics and features shared by members of the group. Organisms are classified into their respective phylum based on shared morphological features or evolutionary relatedness. The Bacteria phylum Aquificae are all hyperthermophilic bacteria that live in ...
Understand species and how organisms are classified within a species. Explore species examples and learn about the characteristics of different...
(which started about 300 million years ago) and even earlier. Because the proteins of mammals as different as whales and humans are very similar, the evolutionary changes that have produced such striking morphological differences must involve relatively few changes in molecules from which we are ...

Some of the other morphological traits of ctenophores include:Diploblastic Exhibit boradial symmetry Have a gastrovascular cavity Nervous system is in the form of a nerve net Possess adhesive structures known as colloblasts (these are located on the tentacles)...
The type of morphological appearance of these cells has also been associated with the pathogenicity of the organism. Given that they are not bacteria, some of these organisms (yeast-like fungi) have characteristics associated with eukaryotic cells in that some have been shown to contain a nucleus...
