Gursky (Eds.), Tarsiers: Past, present, and future (pp. Design, simulation, and testing of a novel bending stage for mechanical characterization of materials. The effects of food viscosity on bite size, bite effort and food intake. A., Zijlstra, N., Mars, M., de Graaf, C., & Prinz, J. Measurement Science and Technology, 7(6), 954-962.ĭe Wijk, R. Their body weight and extraordinary strength are due to robusticity, which is defined as a larger. A portable fracture toughness tester for biological materials. They have almost 9 times the strength of an adult man. Lowland gorillas may be bigger and stronger than mountain gorillas, but all adult gorillas have significant muscle mass and strength. The Apes: Challenges for the 21st Century.ĭarvell, B., Lee, P., Yuen, T., & Lucas, P. Paper presented at the Conference Proceedings. Gorillas have a strong bite, they are generally peaceful and gentle animals and do not use. In comparison, the bite force of a human ranges from around 200-300 psi, while that of a crocodile can be as high as 3700 psi. Future research should include species with body masses between the smaller anthropoids and gorillas by studying the V b of large papionids and the other great apes.Īnthropoid feeding metabolics primate.Ĭonklin-Brittain, N. Silverback gorillas are the dominant males in a group and are responsible for the protection and leadership of the group. The Silverback Gorilla can only run at a top speed of 25 mph. However, the Siberian Tiger is faster on its feet. It can definitely hold its ground and fatally wound its enemy. Notwithstanding, there is still negative allometry in anthropoid V b, in contrast with the isometry in strepsirrhine V b. The Silverback Gorilla has a more powerful bite force. They have a bite force of around 1300 pounds per square inch, double that of a lion. Thus, the addition of the largest living primate brings the anthropoid V b trend closer to the V b trend of the order. Gorillas bite force is one of the strongest in the animal kingdom. However, because the more frugivorous gorillas consumed relatively larger pieces of food than the large folivorous monkeys previously studied, including the gorilla data increased the slope of the linear regression between body mass and V b in anthropoids. When these data were compared to those from our previous studies, we found that gorillas consumed relatively slightly smaller volumes of food compared to the trend found across primates. Gorilla V b ranged from 166.38 cm 3 (for the least obdurate food: watermelon) to 8 cm 3 (for the most obdurate food: turnip), with an average V b of 33.50 cm 3 across all food types. gorilla) were studied to ascertain V b in relation to the mechanical properties of five foods. In the current study, we rectify the omission of great apes from the earlier sample to now characterize the V b of the entire size-range of the order.įive gorillas (Gorilla gorilla gorilla-G. Previously, we found that maximum ingested bite size (V b ), the largest piece of food an animal can consume without biting it into smaller pieces first, isometrically scales relative to body size in strepsirrhines and with negative allometry in anthropoids.
