22. Hypsolodoris tryoni (crawling)



Subject: A Hypsolodoris tryoni crawls on the sandy substrate, leaving behind a trail of mucus. When another individual crosses this trail it will follow it until it catches up with the first snail. From that moment both individuals will crawl together forming a small row. This behaviour is known as tailgating.

Technique: Anticipating an animals behavior can result in nice footage. Predicting the path of this nudibranch (predicting behavior is not always easy with animals but with nudibranchs it is child’s play) allows you to pose the camera along its way, resulting in the animal entering and leaving the frame.
