Out of the frying pan: Coyotes, bobcats move into human-inhabited areas to avoid apex predators — only to be killed by people

In Washington state, the presence of two apex predators — wolves and cougars — drives two mesopredator species — bobcats and coyotes — into areas with higher levels of human activity, with deadly results for the mesopredators.

Study First to Explore ‘Walking’ Sharks on the Move in Early Life Stages

sarah JonasResearch Results

A newly-discovered walking shark that breaks all of the rules for survival is the focus of a first-of-its-kind study that examined differences in walking and swimming in neonate (newly-hatched) and juvenile walking sharks. Despite dissimilarities in body shapes – neonates have bulging bellies and juveniles are slender – the three aquatic gaits they use (slow-to-medium walking, fast-walking and swimming) did not differ. Kinematics between neonate and juvenile epaulette sharks did not alter during development.
