Elephant seal makes ‘epic’ trek back after Canadian officials relocate him

Notorious for drawing large crowds, Emerson was removed by officials who were surprised to find him back in Victoria in a week

Last week, gun-wielding conservation officers stuffed a 500-lb elephant seal in the back of a van, drove him along a winding highway in western Canada and left him on a remote beach “far from human habitation”.

The plan was to move the young seal far from British Columbia’s capital city, where over the last year, he has developed a reputation for ending up in “unusual locations”, including flower beds, city parks and busy roads.

Global heating pushes coral reefs towards worst planet-wide mass bleaching on record

The percentage of reef areas experiencing bleaching-level heat stress is increasing by about 1% a week, scientists say

Global heating has pushed the world’s coral reefs to a fourth planet-wide mass bleaching event that is on track to be the most extensive on record, US government scientists have confirmed.

Some 54% of ocean waters containing coral reefs have experienced heat stress high enough to cause bleaching, the National Oceanic and Atmospheric Administration’s Coral Reef Watch said.

Rope-entangled right whale spotted off coast of New England

The marine mammals are increasingly endangered as warmer waters push them into ship traffic and fishing gear

A North Atlantic right whale has been spotted entangled in rope off New England, worsening an already devastating year for the vanishing animals, federal authorities said.

Right whales number less than 360 and are vulnerable to entanglement in fishing gear and collisions with ships. The entangled whale was seen on Wednesday about 50 miles (80km) south of Rhode Island’s Block Island, the National Oceanic and Atmospheric Administration (NOAA) said.

Scientists find skull of enormous ancient dolphin in Amazon

Fossil of giant river dolphin found in Peru, whose closest living relation is in South Asia, gives clues to future extinction threats

Scientists have discovered the fossilised skull of a giant river dolphin, from a species thought to have fled the ocean and sought refuge in Peru’s Amazonian rivers 16m years ago. The extinct species would have measured up to 3.5 metres long, making it the largest river dolphin ever found.

The discovery of this new species, Pebanista yacuruna, highlights the looming risks to the world’s remaining river dolphins, all of which face similar extinction threats in the next 20 to 40 years, according to the lead author of new research published in Science Advances today. Aldo Benites-Palomino said it belonged to the Platanistoidea family of dolphins commonly found in oceans between 24m and 16m years ago.

Canada moves to protect coral reef that scientists say ‘shouldn’t exist’

Discovery was made after First Nations tipped off ecologists about groups of fish gathering in a fjord off British Columbia

Deep in the hostile waters off Canada’s west coast, in a narrow channel surrounded by fjords, lies a coral reef that scientists believe “shouldn’t exist”. The reef is the northernmost ever discovered in the Pacific Ocean and offers researchers a new glimpse into the resilience – and unpredictability – of the deep-sea ecosystems.

For generations, members of the Kitasoo Xai’xais and Heiltsuk First Nations, two communities off the Central Coast region of British Columbia, had noticed large groups of rockfish congregating in a fjord system.

Gray whale sighted off New England 200 years after species’ Atlantic extinction

Scientists confirm cetacean’s presence but cite impact of climate change which has made North-west Passage ice-free in summer

Scientists have confirmed the presence of a whale off New England that went extinct in the Atlantic Ocean two centuries ago – an exciting discovery, but one they said that illustrates the impact of climate change on sea life.

Researchers with the New England Aquarium in Boston found the gray whale while flying 30 miles south of Nantucket, Massachusetts, on 1 March. The whale, which can weigh 60,000 pounds (27,215kg), typically lives in the northern Pacific Ocean.
