The Tule Elk is a smaller & lighter subspecies of N. American Elk that occurs only in California. Vast numbers thrived in the grasslands of central & coastal California. With the 1800's gold rush, uncontrolled hunting & rapid agricultural development drove them nearly to extinction (almost single digits)!
Harbor seals can dive to 1450 ft & stay submerged for 25 mins! They inhabit the coastal regions of the N. Pacific & Atlantic oceans, & the Arctic regions. They weigh ~180 lbs. and are ~6' in length. Within an hour of birth, most pups can crawl & swim!
Delta smelt, a small fish, is considered a good indicator of the health of the entire Sacramento Delta. Recent counts found only 25 in the entire Delta! Experts suspect a variety of causes: pesticides, invasive species & excessive water exports.
