Which animal has the largest brain relative to its body size?

If terms like “bird brain” and “harebrained” are any indication, animal brains present fascinating and diverse examples of one of the most complex organs known to science. Animal brains differ not only in overall size but also in their size relative to the animal’s body mass.

At 18 pounds (8 kilograms), on average, the sperm whale (Physeter macrocephalus) has the largest brain, but has an overall body mass of 45 tons (40 metric tons), giving it a brain-to-body-mass ratio of 1:5,100. But which animal has the biggest brain relative to its body size?

A 2009 study in the journal Brain, Behavior and Evolution (opens in new tab) found that an especially tiny genus of ant has the largest brain for its body size. Brachymyrmex has an average body mass of up to 0.049 milligrams and an average brain mass of 0.006 milligrams. That means its brain is

In 2003, 47 people across six Midwestern states caught monkeypox from pet prairie dogs that were infected after they were housed with rodents imported from Ghana, Africa.

Today’s outbreak, which has already infected more than 14,100 people in the US and more than 41,000 across the globe, is spreading mostly through close human contact among gay and bisexual men. But scientists reported the first presumed human-to-pet transmission in a dog in France this month, prompting US and global health officials to step up warnings to ensure the virus doesn’t spread to other pets and animals.

The recommendation stems from concerns that monkeypox could spill into wildlife or rodent populations as the human outbreak grows, allowing the virus to pass back-and-forth between humans and animals and giving the virus a permanent foothold in countries where it hasn’t historically circulated

Largest animals on earth shown ‘racing’ at high speed

Blue whales are the largest creatures on the planet and can weigh more than 150 tons, so only rarely are the great leviathans observed traveling at high speeds.

But on Monday off Dana Point, Ca., boaters were in awe as at least three blue whales, perhaps feeling amorous, exhibited racing behavior in a spectacle described by one naturalist as “one for the record books.”

The accompanying video footage was captured by Capt. Dave’s Dana Point Dolphin & Whale Watching. The images were captured by Laura Lopez for Dana Wharf Whale Watch.

In the video, three blue whales are shown interacting in what might be courtship behavior: “Possibly two males competing for the attention of the female,” Capt. Dave’s wrote.

There appears to have been physical contact and, at times, the whales were clocked at 15 knots,

Pilots to the Rescue’s Volunteers Find Animals Forever Homes

Nearly 1 million shelter animals are euthanized every year in America, according to the American Society for the Prevention of Cruelty to Animals, and that’s a statistic that Michael Schneider is determined to change.

The rescue pilot is the founder of Pilots to the Rescue, a nonprofit whose volunteer pilots fly around the country to pick up endangered animals. Their mission? Finding these creatures forever homes with loving families.

Schneider founded the group in 2015 when he was searching for a sense of purpose in his life, but when his corporate events job drastically slowed down during the pandemic, he turned his side work into a full-time gig.

“So it took 45 years for me to realize what I wanted to do when I grow up. This is a real passion of mine and it gives me such a sense of fulfillment, and I love doing this work. It’s
