Fossilised ichthyosaur skull
Fossilised ichthyosaur skull. Close-up of the eye-socket of an Opthalmosaurus sp. marine reptilefrom the late Jurassic period (165 to 150 millionyears ago). It belonged to the ichthyosaur group, which were similar to dolphins with longstreamlined bodies, long snouts and powerfultails. They also had massive eyes. The bony platesseen within the eye socket are thought to haveprevented water pressure from distorting the eye, allowing them to hunt squid and fish at greatdepths. Ichthyosaurs were viviparous (gave birthto live young). Fossil found in Oxford clay inPeterborough, UK

Japanese five-lined skink (Plestiodon latiscutatus)
Japanese five-lined skink (Plestiodon latiscutatus), juvenile with startling colours for survival: predators are attracted to the blue tail that breaks off if grabbed. The skink escapes and hides while the predator is left with the vigorously wriggling tail. The skink grows a replacement, with the same colouring but shorter. Shiga Prefecture, Japan
