The California Academy of Sciences has announced the winners of its annual Big Picture photography competition. This year, the $5,000 Grand Prize went to a golden hour shot of a brown lemur jumping between limestone spires. The lemur leading the group makes the giant vault with her baby clinging to her back.

Aquatic Life winners
The judges also awarded prizes in different categories. In Aquatic Life, another mother and her young took home the gold. A Caribbean reef octopus curls around her children, her tentacles protecting the eggs. Inside each egg, a tiny octopus floats.

The Big Picture also released the finalists in each category, which you can peruse here. In the Aquatic Life category, this wide shot of a green sea turtle is particularly striking.

Terrestrial Life winners
The finalists in this category span the Arctic tundra to deserts and savannas. Highlights among the finalists include this shot in the Chilean mountains of a puma stalking similarly colored guanacos…

…and this dramatic photograph of an elephant and an eland herd in Zimbabwe during the dry season. Dust in the air creates those blood-red African sunsets.

But a pack of Arctic wolves on Ellesmere Island took the prize after curiously thronging the photographer. They were close enough that he could smell their breath.

Winged Life winners
Bats, birds, and bugs galore! But this category doesn’t focus only on photos of winged creatures in flight. Finalists include this moth pupa…

The Honduran white bat took the prize in the Winged Life category. This mother plunges off a leaf to look for food, leaving behind her five pups clustered together like a bunch of berries.

Landscapes, Waterscapes, and Flora winners
This non-wildlife category rewards less dynamic shots than the typical wildlife show stopper. The winning photograph this year documents what looks like an eye but is actually the unfrozen center of a lake in Poland, crisscrossed by animal tracks.

A particularly striking finalist image documents a 2024 cyclone that flooded southeastern Morocco. Once-dry lake beds suddenly revitalized, destabilizing local ecosystems.

Art of Nature winners
This category rewards photographs for which the medium is the message. Unusual shutter speeds, instruments, and sensitivities all have their home here. The winner is this Turner-esque photo of waves off the coast of Germany. A slow shutter speed captured the motion of the water.

One of the finalists in this category also used a slow shutter speed and moving water to create an artistic image. The streaks that grant this starfish a sense of flight arise from the water flowing against the sand.

Human/Nature winners
Many of the finalists in this category emphasize species’ vulnerability or suffering. But the winner shows humans risking their own safety to help an animal. The Kenyan Wildlife Service veterinary team, shown here, attempts to administer anesthesia to an endangered black rhino, an animal more than capable of killing a human even when sedated.
Work by the Kenyan Wildlife Service has gone a long way to protecting this creature, once hunted nearly to extinction.
