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
Updated January 12, 2017 at 9:45 AM. These delightful creatures are called capybaras. Heralded as the world's largest rodents, the South American rainforest natives can actually weigh as much as a ...
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 / krɒkəˈdɪliə /) 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.
For animals like crocodiles, brain matter occupies only 30% to 50% of the brain cavity. Though brain size isn’t a perfect predictor of neuron numbers, a much smaller organ would have far fewer ...
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.
Protocooperation. Protocooperation is where two species interact with each other beneficially; they have no need to interact with each other - they interact purely for the gain that they receive from doing this. It is not at all necessary for protocooperation to occur; growth and survival is possible in the absence of the interaction.
