Zoo Babies: Lion Cubs at the Denver Zoo

On Saturday, my family and I went to the Denver Zoo.  We saw many awesome animals, but probably my favorite animals that we saw were the three new baby lion cubs!  Born in June of 2012, the cubs were sent to the zoo from Qatar, and will likely be shipped somewhere else once any long-term plans have been established regarding where they will stay.  For now, though, we get to enjoy the pleasure of these cubs, and now you can too!  Enjoy the pictures!

Hello there!

King of Pride Rock

The cubs look up as a HUGE flock of geese flies by overhead!  Nice timing, mother!  (That sounds like I'm being sarcastic but I actually am not.)

Ready to pounce!

Right before the goose flyover!

What Is It? The Weekly Challenge #2 Answer

 Hello again!  Thank you to our guessers for this week: surprisingly, one of you got it exactly right!  Congratulations to Kristie C., who guessed this weeks mystery animal 100% correct!  The correct animal was Pakicetus, an ancient ancestor of the cetaceans, or the whales, dolphins and porpoises.  Around 53 MYA, Pakicetus lived in a world that was gradually becoming what we see today.  At this time, what we now know as India was its own special island continent, moving steadily northwards until, eventually, India crashed into Asia.  This crash resulted in the largest mountains we have today, the Himalayas. 

However, 53 MYA, during the Eocene Epoch, India hadn't quite reached Asia, a small sea separating the two, the remains of the vast Tethys Ocean.  The Tethys Sea was high in saline, which is incredibly good for life.  Microscopic organisms like plankton flourished, sending reverberations up the food chain, all of the way to the fish, which exploded in numbers as well.  And on the shore of this Tethys Sea, in what today is Pakistan, stood Pakicetus. 

As Pakicetus watched the gread abundnace of fish in the waters, he began to take short fishing trips into the water.  Over millennia, as Pakicetus took more and more fishing trips, of longer and longer duration, adaptations that proved beneficial for hunting fish in the water occurred, like a more streamlined shape, most likely webbed feet, and nostrils placed further back on the head.  Over a few million years, Pakicetus evolved into another ancient whale, called Ambulocetus.

Check back in a few hours for your next "What Is It?" challenge?  I promise you, after the last two, this one should seem like a piece of cake!  See you all then!

What Is It? The Weekly Challenge #1 Answer

Well, it's that time of the week again!  We only had a few guesses this week, and no one got it exactly right, but there were some close guesses!  The two closest were Kristie C., who guessed an Adélie Penguin, and Masaki K. who guessed Cormorant.  Well, the correct answer to last weeks challenge is Waimanu.  Waimanu is the scientific name of the oldest known fossil penguin.  Two species are known, and both of them were found on the South Island of New Zealand.  One of the species, Waimanu manneringi, lived during the Paleocene, around 61.6 MYA; that means that the oldest known penguin was swimming the oceans only a few million years after the death of the dinosaurs!  Although Waimanu manneringi is the oldest KNOWN fossil penguin, it by no means is the oldest penguin.  In fact, it is quite likely that, were scientists to uncover a fossil that shows when penguins split off from the other orders of birds, we would not even recognize it as a penguin.  Waimanu had undoubtedly already adapted to a fully non-aerial lifestyle, and almost certainly behaved much like modern penguins do when it comes to breeding on land, near the ocean.
