The non-random occupation of habitats is termed habitat selection. Some species of whip spiders select trees with burrows at their base, while others use substrates such as rocks. Here, we investigated the habitat use byCharinusasturiusPinto-da-Rocha, Machado & Weygoldt, 2002, an endemic species of Ilhabela Island in Brazil. We found thatC.asturiusis more likely to be found under rocks that cover larger areas of substrate. Our results also suggest the existence of territorialism inC.asturiusand show thatC.asturiusadults may be found again on the same rock a week later. Additionally, our data show thatC.asturiusis present in a greater area of Ilhabela than previously documented.
