Natural symbiotic relationships have developed throughout the evolution process. Remora fish (e.g. Echeneis neucratoides, sometimes called the “suckerfish”) are considered one of the laziest fish in the ocean as they are more likely to be found attached onto a host with the help of their sucking disc on their head rather than swimming on their own.

Remora fish

Length: 51~73 cm / 25~35 cm

Sea area: Puerto Rico (USA)

This research is primarily focused on the investigations of the effect of the boundary layer flow and the attachment locations, using computational fluid dynamics tools.
