Formerly placed in the pratincole and courser family, Glareolidae, it is now regarded as the sole member of its own monotypic family Pluvianidae. The species is one of several plovers doubtfully associated with the "trochilus" bird mentioned in a supposed cleaning symbiosis with the Nile crocodile. The Egyptian plover is a striking and unmistakable species. The 19–21 cm long adult has a black crown, back, eye-mask and breast band. The rest of the head is white. The
Symbiotic bacteria bugs. Symbiotic bacteria in legume roots provide the plants with ammonia in exchange for the plants' carbon and a protected home. Symbiotic, chemosynthetic bacteria that have been discovered associated with mussels (Bathymodiolus) located near hydrothermal vents have a gene that enables them to utilize hydrogen as a source of energy, in preference to sulphur or methane as their energy source for production of energy. Symbiotic bacteria Symbiotic bacteria are bacteria living in symbiosis with another organism or each other. For example, Zoamastogopera, found in the stomach of termites, enable them to digest cellulose. Symbiosis was first defined by Anton de
