Fin and flipper locomotion (Contra-lateral limbs move together). For example, loggerhead sea turtle hatchlings are commonly seen exhibiting symmetrical gait on sand, whereas, leatherback sea turtles employ the asymmetrical gait while on land. Notably, leatherbacks employ their front (pelvic) flippers more during forward terrestrial locomotion. Sea turtles can be seen nesting on subtropical and tropical beaches all around the world and exhibit such behavior such as arribada (Collective animal behavior). This is a phenomenon seen in Kemp's Ridley turtles which emerge all at once in one night only onto the beach to lay their nests. Fin and flipper locomotion Fin and flipper locomotion occurs
Loggerhead shrike these birds gravitate towards areas of shorter vegetation. Loggerhead shrikes have been repeatedly observed killing prey larger than themselves by spearing the neck or head of the animal and twisting. The speed at which this occurs causes a whiplash injury to the animal. The neck strength of the shrikes compensates, making their talon weakness inconsequential. (source: https://www.afp.com/en/news/2265/head-turning-violence-helps-tiny-songbirds-kill-big-prey-study-doc-18u9wy1 ) Although loggerhead shrikes are passerines, they are a predatory species that hunt during the day. They primarily eat insects, but also consume arachnids, reptiles, amphibians, rodents, bats and small birds. The size of prey ranges from 0.001 g insects to 25 g
