Red-billed oxpeckers have been known to roost in reeds and trees. Studies of large savanna herbivores using cameras at night have shown that both species of oxpecker (but more often in yellow-billed oxpecker) may also roost on the bodies of herbivores, hanging under the insides of the thighs of giraffe and on top of impala and buffalo.

The preferred habitat is open country, and the red-billed oxpecker eats insects. Both the English and scientific names arise from this species' habit of perching on large wild and domesticated mammals such as cattle and eating ticks. [4] This species's relationship with rhinos gives the Swahili name Askari wa kifaru meaning "the rhino's guard". [5]
Red-billed oxpeckers and black rhinos have a symbiotic relationship. The oxpeckers feed on the bugs found on rhinos and the oxpeckers warn the rhinos about nearby poachers. [23] [24] A social relationship was observed between a narwhal and a group of beluga whales in the St. Lawrence River. The narwhal had been accepted into the group of beluga ...
Marine mammal adaptation to an aquatic lifestyle varies considerably between species. Both cetaceans and sirenians are fully aquatic and therefore are obligate water dwellers. Pinnipeds are semiaquatic; they spend the majority of their time in the water but need to return to land for important activities such as mating, breeding and molting.
Whatever the net result, mammals generally tolerate oxpeckers. [8] The yellow-billed oxpecker is 20 cm (7.9 in) long and has plain brown upperparts and head, buff underparts and a pale rump. The feet are strong. The adults' bills are yellow at the base and red at the tip, while juveniles have brown bills. [10] Its flight is strong and direct.

Over 1500 species of fungi are known from marine environments. [160] These are parasitic on marine algae or animals, or are saprobes feeding on dead organic matter from algae, corals, protozoan cysts, sea grasses, wood and other substrata. [161] Spores of many species have special appendages which facilitate attachment to the substratum. [162]
Each symbiotic relationship displays a unique ecological niche, which in turn can lead to entirely new species of host species and symbiont. [ 3 ] It is particularly interesting that it took so long to discover the marine microbial symbiosis because nearly every surface submerged in the oceans becomes covered with biofilm , [ 6 ] including a ...
