Long-distance migratory species are especially punctual in their arrival and departure, often occurring on the same day or within the […]

In every branch of science, a careful and complete description of observed phenomena must precede experimental study. The study of behaviour is certainly no exception to this requirement.When studying a species, however, achieving a comprehensive understanding of its behaviour is a challenging task. It requires patient observation and objective description […]
Among marine organisms, jellyfish are certainly not our species’ favorites. Seeing them nearby while swimming triggers a sudden but justified sense of revulsion, given the stinging cells they possess, which are often truly dangerous even to humans. However, if we could for a moment ignore the unpleasant consequences of encountering […]
