Answer:when visiting the Channel Islands, you can't help but be amazed by creatures such as the island fox, night lizard, deer mouse, island scrub jay, and ashy storm-petrel, just to name a few of the endemic species. The Channel Islands were also once home to the pygmy mammoth, a now extinct dwarf elephant that evolved in this insular environment.

Along with these endemic species are many of what biologists call invasive species, species that originated from elsewhere but have found a home in the Channel Islands. These include sweet fennel, olive trees, and Australian blue gum trees. For a time, elk and deer could also be found here as well.
