Bobtail squids (Cephalopoda: Sepiolida) are growing in popularity as model organisms, not least because of their well-studied symbiotic relationship with light producing bacteria. However, little is known about their behavioural ecology. As part of my M.Sc. thesis at the University of Algarve (Portugal), I went to Okinawa (Japan) to study the behavioural ecology of Eumandya parva (previously Euprymna parva), as well as to Italy to investigate the burying behaviour of bobtail squids. Additionally, I used citizen-science observations to describe the behavioural ecology of wild individuals of Rossia macrosoma from Scottish water. After finishing my M.Sc. thesis, I summarised our knowledge of the ecology of bobtail squids in a review paper.
