Think of this thread when you see any numbers regarding body composition of animals!


Added body fat and muscle mass for a viper and a small constrictor.

Can you view this album?

Yes, I can and will add the information later when I have more time. Thank you very much!


Edit: Added the animals from the charts in your post. Turns out two squirrel species surpass the lion in muscle mass percentage and two bony fish even surpass male human athletes.

Canada lynx is the highest in cats listed here. Is it because they live in cold environment? Is Eurasian lynx similar?


I added the muscle mass of three Lynx species.

Added body fat for three (sub?)families of snakes (Pythoninae, Boinae and Colubrinae).
Is there any way to calculate muscle mass from the crude protein of an animal's body?

Lipid composition in carcass yields of 5 crocodilian species
Posted Image
from the study this table is from
"The proximate composition data of some cuts are showed in Table 1. The average values for proximate composition of M. niger were: moisture content 78.17%, protein 19.23 g%, and lipids 1.09 g%. The mean levels found were similar to those of other studies conducted on other species of crocodilians, as shown in Table 2"

I get easily confused by these tables. Is lipid content equivalent to body fat percentage? Or is that only the fat content of their meat/muscles?

The lipid compisiiton seen in table two is that of what the carcass yielded, table one in the photo shows the different percentages of lipid contents between the cuts of meat.

Does carcass yield correspond to muscle mass?

I do believe so yes, though this wasn't really investigated in this paper.

Anyway, thank you. Added the body fat for these species.

Title: White-Tailed Deer Buck Breeding Strategies: Role of Fat Reserves
Author(s): David G. Hewitt, Aaron M. Foley, Randy W. DeYoung -Caesar Kleberg Wildlife Research Institute; Mickey W. Hellickson - Orion Wildlife Management Services; Karl V. Miller - University of Georgia; Ken Gee - Samuel Roberts Noble Foundation; Mitch Lockwood - Texas Parks and Wildlife Department
Year: 2013
Abstract: In most portions of the species' range, male white-tailed deer accumulate large fat reserves during autumn which they use during the rut. Because movement rate increases during rut, fat may be used to fuel breeding movements. Alternatively, males may use fat reserves to reduce time spent feeding, thereby increasing time available to find, court, and breed females. To understand the role of fat reserves in white-tailed deer breeding, we used movement rates of male deer fitted with GPS collars in southern Texas to calculate energy necessary for rut-based movement. Using rump-fat thickness in mature bucks during a year with high precipitation and good forage, we determined male deer have 25% body fat which, for a buck weighing 175 pounds, translates to 44 pounds of body fat pre-rut. Increased movement during rut requires 173 kcal/day of energy in addition to the 4,280 kcal/day normally expended. Losing 20% body mass during rut releases >110,000 kcal (depending on percent body fat post-rut), which during a six-week rut provides >2,640 kcal/day. Most energy derived from body reserves during rut appears to be used to reduce feeding time, thereby enabling males to devote more time to breeding. Energy from body reserves reduces a male deer's foraging time by >59% over a six-week rut, or more if reserves are used primarily during 2-3 weeks of peak rut. We predict male deer that acquire large fat reserves before rut are more likely to breed because those reserves relieve foraging constraints for a longer period.
