Sighting of Sperm Whales in Arctic Waters 'Really Shocking'

Sperm whales live in all the world's major oceans, but they tend to stay away from extremely cold waters near the poles. So you can imagine the surprise when scientists spotted a pair of these whales farther from their usual range.

World Wildlife Fund-Canada Arctic species specialist Brandon Laforest and his guide Titus Allooloo saw the whales near Pond Inlet, Nunavut in the Canadian Arctic in September, the CBC reported.


They initially thought they spotted killer whales, but later realized it was actually a species rarely seen in the area.

"It's only the second recorded observation of sperm whales in the region. Back in 2014 local hunters spotted them," Laforest told the CBC. He noted it was "really shocking" to see these southern whales so far north.

A clip of the sighting was posted in October:

The head and upper body of a sperm whale contains oily fats that turn waxy in cold waters, meaning they are ill-equipped to swim in colder waters, The Guardian reported. Their fleshy dorsal fins are also ineffective at breaking through ice.

But climate and oceanographic change on sperm whales can potentially affect their typical habitat and feeding range, according to the National Oceanic and Atmospheric Administration.

Laforest told the CBC that the whales he saw have likely returned south, but their stopover in Pond Inlet suggests the region is becoming "more open for them to exploit in terms of accessing food."

Their primary prey is giant squid. Marine biologists have found that squid and other cephalopods are appearing to thrive in warming oceans.

This is good news for sperm whales, Laforest added to the CBC. However, their presence could be bad for Arctic species such as the bowhead "which traditionally live without much competition because of their intense adaptation to live in a relatively harsh environment."

A Record 589 Sea Turtles Killed By Florida's Toxic Red Tide

Florida's longest red tide in more than a decade has killed scores of the state's most iconic marine animals.

The current outbreak, which began in October 2017 off southwest Florida, has been tied to a record 589 sea turtle deaths and 213 manatee deaths, the Herald-Tribune reported, citing figures from the Florida Fish and Wildlife Conservation Commission.

Wildlife Under Siege at the World’s Oldest Lake

By Marlene Cimons

Lake Baikal is the world's oldest and deepest lake. It's at least 20 million years old, and roughly a mile deep at its lowest point. The Siberian lake contains holds more water than all the North American Great Lakes combined, what amounts to more than one-fifth of all the water found in lakes, swamps and rivers. It was formed by the shifting of tectonic plates, which created a valley that filled with water. That shift continues today at a rate of around 1 to 2 centimeters year, meaning the world's biggest lake is only getting bigger.

U.S. Oil and Gas Industry Is Drilling Us Towards Climate Disaster

By Kelly Trout

As the 116th Congress commences, in the wake of dire reports from climate scientists, the debate over U.S. climate policies has taken a welcome turn towards bold solutions. Spurred on by grassroots pressure from Indigenous communities, the youth-led Sunrise Movement and communities from coast to coast fighting fossil fuel infrastructure, Capitol Hill is alive once again with policy proposals that edge towards the scale required to address the crisis we're in.

2018 Was the Hottest Year Ever Recorded for Our Oceans

The year 2018 was the hottest year for the planet's oceans ever since record-keeping began in 1958, according to a worrisome new study from international scientists.

The findings, published Wednesday in the journal Advances in Atmospheric Sciences, noted that the five warmest years for our oceans were the last five years—2018, 2017, 2015, 2016 and 2014 (in order of decreasing ocean heat content).

Senate Shouldn’t Put Wheeler at the Wheel of the EPA

By Ana Unruh Cohen

As the longest government shut down in history drags on, and the experts protecting our air and water remain off the job, the Senate is barreling forward to put Andrew Wheeler at the wheel of the U.S. Environmental Protection Agency (EPA). He is unfit for this public trust.

In his seven-month tenure as the acting administrator at EPA, Wheeler's relentlessly pushed to advance the pro-polluter agenda launched by Scott Pruitt, the worst administrator in the agency's storied 48-year history. Wheeler may lack Pruitt's scandals, but he's no improvement.
