The blob is the nickname given to Physarum polycephalum, a single-celled living organism that is neither animal, plant, nor fungus. Despite having no brain or nervous system, it can move, remember a route, and solve simple problems such as finding food inside a maze. It belongs to the myxomycetes, a group of giant single-celled organisms.

The blob doesn't fit into any of the usual boxes of the living world. It is made of a single cell, yet that cell can spread across several square metres and contain millions of nuclei. With no brain or neuron, it still senses its environment, avoids certain substances, seeks out others, and adapts its behaviour based on what it has already explored, a form of purely cellular memory. This ability to optimise its movements without calculation or awareness interests biologists and computer scientists alike. When conditions no longer suit it, it doesn't die: it withdraws into sclerotia, a dry, inert form, and can stay that way for years before waking up on contact with water.

The sclerotia sold by NeoBloby come from the CNRS AVA strain (Badhamia variety, Physarum polycephalum), selected and maintained. Every batch is checked before shipping and produced in France. The blob is delivered in its natural dormant state, stable for transport and ready to wake up as soon as it arrives.
Three names, three different things. Physarum polycephalum is the scientific name of the species commonly nicknamed “the blob”. Bloby is the brand's mascot: a character that embodies the blob in our illustrations and our online assistant, without being a living organism itself. NeoBloby, finally, is the name of the company that breeds, packages and ships you these living blobs along with their rearing kit.
