Invertebrates are abundant and all around us. Only the colorful ones have been known better and praised eg butterflies. There are others in the same family eg moths that have received less attention. Beetles are known for their commercial value in international trade or weevils are known as a pest. Spiders are colorful and plenty but have been portrayed as a fearsome creature. Studies on mollusks are underway only very recently. There is so much biodiversity but so little has been done.

In matters of invertebrate conservation, we remain advised by Buglife International: the global conservation organization dedicated to conserving world's invertebrate diversity. Recent progress in understanding the principles and mechanisms in olfaction is the result of multidisciplinary research efforts that explored chemosensation by using a variety of model organisms. Studies on invertebrates, notably nematodes, insects, and crustaceans, to which diverse experimental approaches can be applied, have greatly helped elucidate various aspects of olfactory signaling. From the converging results of genetic, molecular, and physiological studies, a common set of chemosensory mechanisms emerges. Recognition and discrimination of odorants, as well as chemo-electrical transduction and processing of olfactory signals, appear to be mediated by fundamentally similar mechanisms in phylogenetically diverse animals. The common challenge of organisms to decipher the world of odors was apparently met by a phylogenetically conserved strategy. Thus, comparative studies should continue to provide important contributions toward an understanding of the sense of smell.

Found in every type of habitat, invertebrates are essential to our ecosystems as they recycle waste into useful products, pollinate plants and provide natural pest control. These roles provide immense benefits to humans and we depend on the pollination of crops by insects for our food and livelihoods. Invertebrates are also a source of food for many species including humans and the diets of some birds, amphibians, fishes, and mammals are entirely dependent on them.

Invertebrates constitute 99% of the world’s species, and a staggering one in five species could be at risk of extinction. Threats to invertebrates include habitat destruction, exploitation and climate change. It is important that action is taken to conserve invertebrate species so the essential services and benefits they provide to ecosystems are protected.
