Stochastic mapping of the Life Habit character. Red, ‘aquatic’; dark green, ‘terrestrial’; blue, ‘fossorial’; yellow, ‘arboreal’; orange, ‘aquatic + terrestrial’; turquoise, ‘terrestrial + fossorial’; light green, ‘terrestrial + arboreal’. Plain arrows: convergent transitions from fossorial to terrestrial or to fossorial+terrestrial habitats; dashed arrows: secondary transitions to the aquatic environment. Multiple transitions to the arboreal state have also occurred but are not marked by arrows
