Planner graph on Kemp Ridley and Olive Ridley turtles' carapace

Kemp's Ridley or Lepidochelys kempii is the smallest of all sea turtle species. Reaching maturity at 2–3 feet (61–91 cm) long and averaging only 45 kilogram. It's carapace contains five vertebral scutes running down the midline, while five pairs of costal scutes border them. The resulting planar graph due to this scalation is 3-regular 28 vertices and 42 edges. Exactly same as as that of Loggerhead or Caretta Caretta.

Olive Ridley or Lepidochelys olivacea is also one of the smallest turtle species. its heart-shaped carapace is characterized by four pairs of pore-bearing inframarginal scutes on the bridge, two pairs of prefrontals, and up to nine lateral scutes per side. Scalation can be asymmetrical i.e. 6 lateral scutes on one side and 8 on the other.
