Weight

Weights of ornate box turtles varied so much that no attempt was made

to correlate weight with size. Absolute weights have little

significance since weight is affected to a large extent by the amount

of fluid in the body. Turtles that had recently imbibed were naturally

heavier than those that had not; turtles brought to the laboratory and

kept there for several days lost weight by evaporation and by voiding

water. Weights of 22 adult females (53 records) and 10 adult males (22

records) averaged 391 and 353 grams respectively, in the period from

September, 1954, to October, 1956. Females characteristically gained

weight in spring and early summer and were lighter after nesting.

Turtles of both sexes gained weight in September and October.
