Passage: The bog turtle is the smallest species of turtle in North America. The adults weigh approximately 110 grams (3.9 oz) when fully grown. It does not have a prominent snout. Its head is dark brown to black; however, it has a bright yellow, orange, or red spot on each side of its neck. The spot is often forked, facing posteriorly. The bog turtle has a dark skin color with an orange-red wash on the inside of the legs of some individuals. The carapace is domed and rectangular in shape, and it tends to be narrower toward the head and wider toward the tail. The carapace often has easily identifiable rings on the rough scales or scutes. The scutes may also have a radiating arrangement of lines. In some older individuals, and those that burrow frequently in coarse substrates, the shell may be smooth. Although generally black, a chestnut sunburst pattern in each scute is sometimes present on the carapace. The belly of the shell, the plastron, is also a dark brown to black color with light marks present.
