Megapixels: An epic wildebeest crossing, a really hungry fox, and more Smithsonian Photo Contest finalists

Plus, a lava lizard perched atop a marine iguana.

The best photography reminds us of the supreme beauty of our natural world, the pain we inflict on it, why we must protect our planet, and what it means to be human. The winners and finalists of this year's Smithsonian Photo Contest do all of that (and more), depicting scenes of playful whales, the humbling aftermath of wildfires, a sneaky Arctic fox stealing a hunk of meat bigger than its own head, and a newborn baby on his father's lap. You can see the complete collection of the winning photos here. Scroll down to see a sampling of our favorites.

Playing With the Wave

This baby humpback whale, captured on a Nikon D810, playfully rolls in the waves. Adult humpbacks grow to be as large as school buses, and they swim in every ocean in the world. This one frolicked in the waters of Tonga, a Polynesian kingdom in the South Pacific.© Reiko Takahashi. All rights reserved.

The Impassable

Icelandic landscapes are so uniquely breathtaking that filmmakers often use them to depict other worlds, as in Star Wars: The Force Awakens, Interstellar, and Star Trek: Into Darkness. The Ófærufoss waterfall, pictured above, hasn't been in a film yet, but it certainly could be. It's a part of the Nyrðri-Ófæra river, also known as the "impassable northern river," which flows into Eldgjá, or the "Canyon of Fire."© Andro Loria. All rights reserved.

Red-Fronted Lemur

This red-fronted lemur was captured by photographer Anuroop Krishnan on a Canon EOS 5D Mark III. This species is native to Madagascar, like all extant lemurs, and is listed as vulnerable due to slash-and-burn agriculture and illegal logging.© Anuroop Krishnan. All rights reserved.

an arctic fox carrying meat

Hungry Fox

Photographer Patrizia Ricci was in Canada's Wapusk National Park looking for polar bear cubs, but instead happened upon this hungry fox. Arctic foxes are scavengers and known to steal from other predators, which could be why this one is carrying a big hunk of caribou meat.© patrizia ricci. All rights reserved.
