Diamondback Terrapin

Description:

The common name refers to the diamond pattern on top of its shell (carapace), but the overall pattern and coloration vary greatly. The shell is usually wider at the back than in the front and from above its appears wedge shaped. Its shell coloring can vary from browns to greys, and its body color can be grey, brown, yellow, or white. All have a unique pattern of wiggly, black markings or spots on their body and head. The diamondback terrapin have large webbed feet. The species is sexually dimorphic in that the males grow to approximately 13 cm (5.1 in), while the females grow to an average of around 19 cm (7.5 in), though they are capable of growing larger. The largest female on record was just over 23 cm (9.1 in) in length. Specimens from regions that are consistently warmer in temperature tend to be larger than those from cooler, more northern areas. Male diamondback terrapins weigh 300 g (11 oz) on average, while females weigh around 500 g (18 oz). The largest females can weigh up to 1,000 g (35 oz).
