Cleaning symbiosis is a relationship between a pair of animals of different species, involving the removal and subsequent ingestion of ectoparasites, diseased and injured tissue, and unwanted food items from the surface of the host organism (the client) by the cleaning organism (the cleaner).
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 .
Supposed cleaning symbiosis Main articles: Trochilus (crocodile bird) and Cleaning symbiosis The "spur-winged plover" was identified by Henry Scherren as the "trochilus" bird said by the Greek historian Herodotus [8] to be involved in what would now be called a cleaning symbiosis with the Nile crocodile .

Unlike other crocodiles, the American crocodile uses acoustic signals to communicate. Crocodile communication is centered on short-distance communications during courtship and hatching. Cleaning symbiosis involving fish and the American crocodile has been described. Hunting and diet Adult male C. acutus
Aristotle records the same pattern of cleaning symbiosis reported by Herodotus, but differs as to its purpose, stating that "when the crocodile gapes, the trochilus flies into its mouth, to cleanse its teeth", presumably to feed on decaying meat lodged between the teeth and gums.
Crocodilia (or Crocodylia, both / k r ɒ k ə ˈ d ɪ l i ə /) is an order of mostly large, predatory, semiaquatic reptiles known as crocodilians.They first appeared 94 million years ago in the Late Cretaceous period (Cenomanian stage) and are the closest living relatives of birds, as the two groups are the only known survivors of the Archosauria.
Dietary biology of the Nile crocodile. Nile crocodiles are apex predators throughout their range. In the water, this species is an agile and rapid hunter relying on both movement and pressure sensors to catch any prey that presents itself inside or near the waterfront. [1] Out of the water, however, the Nile crocodile can only rely on its limbs ...
Cleaning symbiosis is well known among marine fish, where some small species of cleaner fish – notably wrasses, but also species in other genera – are specialized to feed almost exclusively by cleaning larger fish and other marine animals.
The mugger crocodile ( Crocodylus palustris) is a medium-sized broad- snouted crocodile, also known as mugger and marsh crocodile. It is native to freshwater habitats from southern Iran to the Indian subcontinent, where it inhabits marshes, lakes, rivers and artificial ponds. It rarely reaches a body length of 5 m (16 ft 5 in) and is a powerful ...
The false gharial is a mound-nester. Females lay small clutches of 13–35 eggs per nest and appear to produce the largest eggs of living crocodilians. They attain sexual maturity at a length of around 2.5 to 3 m (8 ft 2 in to 9 ft 10 in), which is large compared to other crocodilians. [25]
