Classification. Since the 1980s, gastropod classification has been the subject of extensive debate. Major revisions based on detailed information about traditional anatomy and shell features have been challenged by cladistic attempts to identify changes that have taken place once in the evolutionary history of a group.

The taxonomic classification system (also called the Linnaean system after its inventor, Carl Linnaeus, a Swedish botanist, zoologist, and physician) uses a hierarchical model. Moving from the point of origin, the groups become more specific, until one branch ends as a single species. For example, after the common beginning of all life.

Planorbidae, common name the ramshorn snails or ram's horn snails, is a family of air-breathing freshwater snails, aquatic pulmonate gastropod mollusks. Many of the species in this family have coiled shells that are planispiral, in other words, the shells are more or less coiled flat.

Differ from all sharks in lacking upper free eyelid. More than 500 species. Jurassic to present. Subclass Holocephali. Jaws holostylic (the palatoquadrate.

Stephen Endlicher published his “Genera Plantarum” (1836-1840) describing 6,835 genera and arranged them in a system of his own. Here he divided the plant kingdom into 2 regions, viz., Thallophyta and Cormophyta. The Thallophyta included plants with simple structure, without stem or root or vessels and without clearly defined sex-organs, e.

Ecology: Instream habitat: Planorbidae species occur in slow-moving and still waters where they are found amongst macrophytes and algae. Feeding ecology: Planorbid snails feed macrophytes and algae. Habit: Isidorella newcombi is able to aestivate in the mud when conditions become unfavourable. Life history: Planorbidae species are hermaphrodites capable of self-fertilisation.

There are nearly 10,000 different species of bird. They range from the huge ostrich, which stands taller than a person, to the tiny bee hummingbird, which weighs less than an acorn. Many, such as the chiffchaff and willow warbler, look very similar to each other. But each one is adapted to cope with the environment in its own unique way.

Generally, snails are looked at with disgust. Gardeners are particularly unfriendly towards their slimy cohabitants and everything thinkable (and some things unthinkable) is done to get rid of them.
