Today's Seals Are: Robot Uprising

Begging you for some pinnipeds any pinnipeds please

Piebald Northern fur seal

Atypical colored Antarctic fur seal! With the orange, white, and grey they look calico.

Leucistic Antarctic fur seal

Interesting gang of Antarctic fur seal, one is leucistic and one almost looks brindle?

Leucistic southern elephant seal

Northern fur seal labeled as albino and partial albino (leucistic?) by some sources. NOAA says albino and they are experts.

Albino harbor seal

Albino ringed seal

Melanistic grey seal

welcome to my blubbery blog!!! 🦭🦦🐋🐬🫧

i’m currently a volunteer at an AZA accredited aquarium, i hope to study marine environmental science in the future and work in conservation and education! my primary interests are in northern fur seal biology and southern resident killer whale behaviour, but i love all marine mammals!

i support accredited* zoos and aquariums! i do however hope that we can move away from them in the future. i think that conversations about the ethics of captivity are important and should always be centered around the wellbeing of the captive animals. i encourage caution and use of critical thinking around both anti and pro captivity arguments. i’m always happy to answer any questions about the practices of AZA accredited zoos and aquariums!

*there are some accredited zoos and aquariums (such as seaworld) that i am heavily critical of, but it’s unfortunately a complicated issue that isn’t realistic to have black and white opinions on.

Humpback Whales Are Singing More: Number of Songs Has Doubled as Food Sources Became More Abundant

Eavesdropping on whale songs over 6 years shows the number of days humpbacks have been singing has nearly doubled–with their food source.

"Eavesdropping on whale songs over the last six years is providing new information vital to answering questions about these giants of the ocean.

The number of whale songs detected is associated with shifting food sources, according to the California scientists—and the number of days humpbacks have been singing has nearly doubled.

When monitoring baleen whale songs in the Pacific Ocean, researchers found year-to-year variations correlated with changes in the availability of the species they forage on.

In vast oceans, monitoring populations of large marine animals can be a “major challenge” for ecologists, explained Dr. John Ryan, a biological oceanographer at the Monterey Bay Aquarium Research Institute in California (MBARI).

Their team deployed underwater microphones called hydrophones to study and track baleen whales, which communicate over long distances through sound.

“Surprisingly, the acoustic behavior of baleen whales provides insights about which species can better adapt to changing ocean conditions,” said Dr. Ryan, a lead author of the study.

They also monitored songs from blue, fin, and humpback whales off the West Coast of the U.S. to see what the song data could reveal about the health of their ecosystem.

The findings, published in the journal PLOS One, showed “large” year-to-year variations in whale song detection.

“The amount of humpback whale song continually increased, with their songs being detected on 34% of days at the beginning of the study and rising to 76% of days after six years,” said Dr. Ryan.

“These increases consistently tracked improved foraging conditions for humpback whales across all study years—large increases in krill abundance, followed by large increases in anchovy abundance.

“In contrast, blue and fin whale song rose primarily during the years of increasing krill abundance.

“This distinction of humpback whales is consistent with their ability to switch between dominant prey. An analysis of skin biopsy samples confirmed that changes had occurred in the whales’ diets.”

He explained that other factors, including the local abundance of whales, may have contributed to patterns in song detections observed in some years, but changes in foraging conditions were the most consistent factor.

“Overall, the study indicates that seasonal and annual changes in the amount of baleen whale song detected may mirror shifts in the local food web.”

WHALES ON THE COMEBACK TRAIL: • Gray Whale, Extinct for Centuries in Atlantic, Is Spotted in Cape Cod • Sighting of Many Blue Whales Around Seychelles is First in Decades – ‘Phenomenal’ • Majestic Sei Whales Reappear in Argentine Waters After Nearly a Century

“The results suggest that an understanding of the relationship between whale song detection and food availability may help researchers to interpret future hydrophone data, both for scientific research and whale management efforts”, which could better protect endangered species."

i love this "with mama" meme. mm yes give me more baby animals with mmama.

please stop calling the california sea lions that are acting abnormally “demonic”. they are experiencing domoic acid toxicosis. domoic acid (DA) is a neurotoxin that is made by an algae called pseudo-nitzschia australis. fish eat the algae and the sea lions eat the fish. this buildup of DA in their system is what causes the behaviours we’re seeing. symptoms of DA toxicosis include: lethargy, disorientation, unpredictable behaviour, seizures, brain damage, and eventually death.

as far as we know, there have only been two unprovoked sea lion attacks on beaches. the vast majority of sea lions with DA toxicosis are not aggressive unless provoked. they are disoriented and they are acting out of fear.

DA is naturally occurring, but the algal blooms of pseudo-nitzschia australis have been increasing due to rising temperatures from climate change and water pollution. we are doing this to them.

affected sea lions seem to have pretty much a 50% chance of survival with treatment. they need IV fluids to flush out the toxin and some will need seizure medication as well. the marine mammal care center is completely overwhelmed with the amount of sick sea lions they are taking in and they need funding to keep up. you can donate to them here.

always stay at least 45 meters / 50 yards away from marine mammals! it protects both them and us!

Animal welfare advocacy should be about the animals, not an agenda
