For the species tested, the process | metamorpho- sis demanded markedly more energ\ than did a larval swim- ming duration ol maximal length (Fig. 51. For example. individuals ol H. neritina expended almost 4 times more energ> during metamorphosis than they did for 20 h ol swimming, which was considered a maximum swimming duration (estimated from Fig. 2). Larvae of B. stolonifera. the smallest lar\a. consumed approximately twice as much energy during metamorphosis as during a maximal swim- ming period of 1(> h (estimated from Fig. 2). The metabolic- cost of larval swimming was similar for each species. whereas the cost of metamorphosis was significantly higher lor species with larger larvae. Metamorphosing indi\ iduaK of H. neritina used approximate!) 4 times more energy to complete metamorphosis than did those of K. stolonifera.
