How Did You Get Here?! (Unexpected Ways Species Travel the World)

The video explores the concept of disjunct distribution, where species are found in unexpected locations. It highlights human influence on species spread, using the example of pygmy shrews in Ireland. The video also discusses natural causes of distribution, such as range fragmentation in armadillos and continental drift affecting marsupials. Biological adaptations like mangrove seed buoyancy and unique dispersal methods of killifish are examined. Finally, it covers iguanas crossing oceans via natural rafts, illustrating the complex ways species distribute globally.

What unique adaptations do mangrove trees have for seed dispersal?

Discuss the unusual dispersal method of Killie fish as mentioned in the text.

What evidence suggests that iguanas may have rafted to islands?
