Setae on the legs of krill and other small crustaceans help them to gather phytoplankton. It captures them and allows them to be eaten. Setae on the integument of insects are unicellular, meaning that each is formed from a single epidermal cell of a type called a trichogen, literally meaning "bristle generator". They are at first hollow and in ...
Each frustule has four hollow processes called setae, or spines, that allow adjacent cells to link together and form colonies. [2] Colonies can form chains that are coiled, straight, or curved. Cell size can range from <10 um to 50 um. [5] Some species of Chaetoceros produce resting spores that are highly tolerant to adverse conditions. [2]

Disciplines vary between universities and even programs. These will have well-defined rosters of journals and conferences supported by a few universities and publications. Most disciplines are broken down into (potentially overlapping) branches called sub-disciplines.
In both those examples there is heavy modification by sclerotisation. Again, contrasting strongly with both unmodified organic material such as largely pure chitin, and with sclerotised chitin and proteins, consider the integument of a heavily armoured crab, in which there is a very high degree of modification by biomineralization.
