As a result, the best flight for imaging jellyfish with clarity, and to ensure that individual jellyfish are not captured in multiple images, needs to be calculated based on field observations (Raoult and Gaston 2018; Schaub et al. 2018).

However, each bat species is likely to use several shapes to gain information on habitat and prey distance and size. Aldridge and Rautenbach (1987) found...

Most of the bats, however, continued to use a 200 mm high × 600 mm wide gap between the top of the grate and the irregularly-shaped cave roof, despite this requiring a more circuitous flight path. The study concluded that the addition of bat windows...
