About small yet beautiful flatworm – Prostheceraeus sp: They inhabit majority of the oceans and seas in the world and vary in size, shape, built, colour and translucence and the area where they are located and what they eat. Listed is some interesting information for a read.

There are approximately 20,000 different species, of which the majority are parasitic. They are the simplest animals that are bilaterally symmetrical. Most or all species of polyclads have light-sensitive eyespots. The highly branched structure also allows food to be transported to all parts of the body.

Monogeneans have an indirect life-cycle, meaning the always have more than one host species. In some secondary and tertiary mesenteries are incomplete. Some species have fewer cycles of mesenteries compared to others free swimming for the whole of their life Ciliated flatworms. Inhabit waters where temperatures stay around 33°C.

They may have been formed by resorption rather than being built. They have complex life cycles often involving two or more host organisms. The main ascidian predators known in nature are flatworms these species span a wide range of fecundity. They do not have skeletons, however they do have an endoderm. Flatworms in scientific literature are known as Platyhelminthes or Plathelminthes. Cestodes (tapeworms) have complex life-cycles. Members of all classes except Turbellaria are parasitic during all or part of the life cycle.

Most turbellarians are exclusively free-living forms. They can be carnivors, scavengers or herbivours. Flatworms are hermaphroditic (having both male and female sex organs). Prostheceraeus sp flatworms are triptoblastic, meaning there are three primary germs. Their individual cells have the ability to sense and react to changes in their surroundings where they are situated.

In terms of motility, most have flagella or cilia at some point in their life cycle. They have have tubular digestive systems. Flatworm Prostheceraeus villatus and its tunicate prey Clavellina. All in all an interesting organism with a wide variety for researchers, students and even laymen interested for further study.
