Ichthyosaurs (Greek for "fish lizard") were large marine reptiles that lived alongside the dinosaurs during most of the Mesozoic era.

Coral Larvae Cryogenically Frozen and Thawed for the First Time

Warming oceans are killing the world’s reefs, but scientists may have found a way to help them get out of hot water—by putting corals into a deep freeze

The marsupial lion (Thylacoleo carnifex) stalked Australian forests tens of thousands of years ago.

How a Changing Climate May Have Killed Off the Marsupial Lion

The fearsome predator, related to koalas and wombats, ruled the wilds of Australia until the loss of its habitat helped drive it to extinction

Princepajaro, a male California sea lion, swims in a pool during treatment for leptospirosis at The Marine Mammal Center in Sausalito, CA. When a leptospirosis outbreak occurs, the Center’s scientists study the disease to learn more about what causes an outbreak and how we can improve treatment for infected animals.

Major Disease Outbreak Strikes California Sea Lions

Leptospirosis afflicts sea lions on a semi-regular cycle, but warming waters and migrating fish could make the marine mammals more susceptible

Baby bats are born tipping the scales at a third of their adult weight, and since mama bats have to carry them until they can fly, at which point they are nearly full-grown, it’s no wonder they start to get a bit physical.

Mama Bats Literally Nudge Their Babies Out of the Roost

Researchers observed mother bats repeatedly prodding their young to motivate them to fledge

In areas made up of less than 70 percent native plant biomass, Carolina chickadees will not produce enough young to sustain their populations. At 70 percent or higher, the birds can thrive.
