**The animal kingdom, a high-level classification of living organisms (as contrasted with plants, fungi, and other).He Campaign supports the efforts to redirect electrical and electronic waste – e-waste –away from environmentally unsound landfill, open-pit burning and harmful recycling operations. Safe Planet seeks to protect the environment and improve the health and welfare of workers in the informal sector as part of UNEP´s efforts to build a global “Green Economy” of green jobs. In the 2010 International Year of Biodiversity, the Campaign’s slogan “A Planet Safe for All Living Things” served as a link of the chemicals and waste management to the protection of endangered species.The international project “We Help Gorillas” was launched by Prague Zoo as the Safe Planet project to foster mobile phone recycling and to raise awareness of the threats to gorilla populations living in Africa’s Congo Basin. This project spread to thirteen zoos in the Czech Republic and served as a model of public involvement in e-waste recycling, which is promoted by Safe Planet and the Basel Convention.Is a large phylum of invertebrate animals.  ** **There are around 85,000 recognized extant species of molluscs. This is the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. Molluscs are highly diverse, not only in size and in anatomical structure, but also in behaviour and in habitat. The phylum Mollusca is typically divided into nine or ten taxonomic classes, of which two are extinct. The gastropods (snails and slugs) include by far the most classified species, accounting for 80% of the total. Cephalopod molluscs such as squid, cuttlefish and octopus are among the most neurologically advanced invertebrates. Either the giant squid or the colossal squid is the largest known species of animal without a backbone. The two most universal features of the body structure of molluscs are a mantle with a significant cavity used for breathing and excretion, and the organization of the nervous system. Because of the great range of anatomical diversity, many textbooks base their descriptions on a hypothetical "generalized mollusc", with features common to many but not all classes within the Mollusk. An arthropod is an invertebrate animal having an exoskeleton (external skeleton), a segmented body, and jointed appendages.  ** **Arthropods are members of the phylum Arthropoda and include the insects, arachnids, crustaceans, and others. Arthropods are characterized by their jointed limbs and cuticles, which are mainly made of the cuticles of crustaceans are also biomineralized with calcium carbonate. The rigid cuticle inhibits growth, so arthropods replace it periodically by molting. The arthropod body plan consists of repeated segments, each with a pair of appendages. It is so versatile that they have been compared to Swiss Army knives, and it has enabled them to become the most species-rich members of all ecological guilds in most environments. They have over a million described species, making up more than 80% of all described living animal species, and are one of only two animal groups that are very successful in dry environments – the other being the amniotes. They range in size from microscopic plankton up to forms a few meters long. Arthropods' primary internal cavity is a hemocoel, which accommodates their internal organs and through which their bloodcirculates; they have open circulatory systems. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. Their nervous system is "ladder-like", with paired ventral nerve cords running through all segments and forming paired ganglia in each segment. **

**Their heads are formed by fusion of varying numbers of segments, and their brains are formed by fusion of the ganglia of these segments and encircle the esophagus. The respiratory and excretory systems of arthropods vary, depending as much on their environment as on the subphylum to which they belong. The phylum contains about 7,000 living species, making it the second-largest grouping of deuterostomes, after the chordates. Echinoderms are also the largest phylum that has no freshwater or terrestrial representatives. The echinoderms are important both biologically and geologically: biologically because few other groupings are so abundant in the biotic desert of the deep sea, as well as the shallower oceans, and geologically as their ossified skeletons are major contributors to many limestone formations, and can provide valuable clues as to the geological environment. Further, it is held by some that the radiation of echinoderms was responsible for the Mesozoic revolution of marine life.**

** All echinoderms are marine organisms. In the larval stage, most echinoderms arebilaterally symmetrical. Most adults are radially symmetrical. They have aventral mouth, an internal skeleton of calcium carbonate plates, and a water vascular system consisting of tube feet, radial canals, and a ring canal for movement. **Birds** **class Aves are feathered, winged, bipedal, endothermic (warm-blooded), egg-laying, vertebrate animals. Around 10,000 living species makes them the most speciose **class of tetrapod vertebrates**    **  **

 
 * The reproduction of freshwater mollusks from adult to an adult occurs in a variety of stages. The first stage is the water column in which the sperm flows with the water current until a female siphons the water, collects the sperm and fertilizes her eggs.**
 * After fertilization takes place, it may take 1 to 10 months for the larva,** **to fully develop within the female. When the glochidia are fully developed in early spring or fall, they are released into the water where they drift until they find a suitable fish host. Unionaceans are divided into two distinct behavioral groups depending on when the female disperses the glochidia, bradytictic or tachytictic . Bradytictic (long term breeders) hold their larvae throughout the winter until the following spring or summer The tachytictic (short term breeders) release the larvae later the same year, usually by July or August.**
