Heart and circulatory functions in a spider (Eurypelma californicum): the effects of hydraulic force generation

Abstract

In the tarantulaEurypelma californicum, the relationships between heart activity, circulation and the generation of hydraulic pressure for locomotion were studied. Several new techniques were employed. Mean resting heart rate was 21 beats min−1 rising to 90 beats min−1 after burst activity. Decay time to resting rates was related to the increase of heart… (More)
