SILVA, Lidiane et al. Basic ethogram, aggregative behavior and preference for site rest in Bulimulus tenuissimus (d'Orbigny, 1835) (Mollusca, Bulimulidae) in laboratory conditions. Rev. etol. [online]. 2011, vol.10, n.1, pp. 27-33. ISSN 1517-2805.

The behavior of land snails is few studied, although it represents an important tool for conservation or control of such animals. Thus, it was aimed to describe the basic ethogram of Bulimulus tenuissimus, verify occurrence of aggregative behavior and preference for site rest. To describe the ethogram, groups of 15 snails was observed for 24 hours by the scanning method at intervals of 10 minutes. To verify the aggregative behavior, other 50 animals were divided into groups of 10 animals and kept in plastic terrariums previously divided into quarters. Aggregation was established by the number of snails/quadrant and the preference for site rest, by the number of snails in pre-determined positions. It was confirmed the nocturnal habits of this species, and the most frequents acts behavioral were explore and food. It wasn't observed aggregative behavior and the terrarium's wall was the site rest most often used by snails.
