Tonight the Discovery Channel will air its third installment of the show “Alien Sharks” as part of Shark Week. As in its previous two installments, this show will explore the amazing diversity of deep-sea sharks that, because of their natural habitat, are rarely seen by human eyes.
The deep sea is a place of great mystery and intrigue. Ancient mariners thought it was home to sea serpents and kraken, which emerged to drag ships to their doom. While we now know that some of these “monsters” suffered from mistaken identity — sea serpents were likely oarfish or eels, and the kraken was probably giant squid — we still know almost nothing about the deep sea.
Years ago, I had a rare glance into this realm — and an up-close look at an “alien” of the deep.
