Comments "Studies investigating the swimming of larger-scale animals, however, have reported higher efficiency: about 10% and 5%, for a rainbow trout (Salmo gairdneri) swimming with undulating body and/or fins (primary source [1]) and a squid (Illes illecebrosus) with jet propulsion (primary source [2]), respectively. These facts demonstrate that the energy cost of swimming in Paramecium is about two-orders of magnitude lower than in these larger animals."
