The representatives of the family Porcellanidae are crustaceans very common and abundant on rocky habitats in the intertidal zone, sheltering under rocks among algae and establishing commensally
relationships with some another species of the hard bottoms, such as sea anemones, and starfishes.
Most commonly identified microorganisms were part of the normal commensally
flora with the highest frequency for Staphylococcus epidermidis (4/11 or 36.
Fungi are the predominant contaminants of spices , but most such microbial populations are probably regarded as commensally
residents on the plant.
Some non-native species live commensally
with humans and these species show the opposite pattern, i.
Mus are generally considered both territorial and colonial when living commensally
The parasitic interactions between phorids and ants have thus been relatively well studied (Feener & Brown 1997; Brown 1999), but less is known about the evolution of their association and the behavior of phorids living commensally
within ant nests, especially concerning nonparasitic interactions between these two groups (Holldobler & Wilson 1990).
They are found commensally
in the body flora, where they cause sinusitis, pneumonia, intra-abdominal infection, and genitourinary infection in humans, as well as when in conjunction with facultative anaerobic bacteria (ie, Klebsiella pneumoniae, Proteus mirabilis, and Escherichia coli).
This fish lives free and commensally
with infaunal invertebrates (MacGinitie and MacGinitie 1949).
