Juvenile pygmy sperm whale washed ashore today Amagansett, Long Island. They only get to about 9 feet and are the smallest of whales. They’re usually in the tropics and in deeper seas. Here’s a video primer. Apparently very rare to see a beached juvenile whale, and even rarer this for species so far north. The commentary:

Incredible day in Amagansett.

A 50-foot fin whale washed up dead on the ocean beach; it had probably been dead a week.

Then, in a truly bizarre coincidence, a once-in-a-lifetime rarity and not normally an animal even found in this region, a pygmy sperm whale, a juvenile, washed up alive 2 miles down the beach. It was an astonishing thing to see. Sadly, it was euthanized later in the day.

Cause of death unknown…Pygmy sperm whale had some skin lesions suggesting bacterial infection. Did not seem thin. Ingestion of plastic always a possibility. They’ll be examined more closely via necropsy in coming days.

A 9.5 ft Pygmy Sperm Whale (Kogia breviceps). Upon necropsy, found to be pregnant. The mother had head trauma consistent with fishermen beating it as it struggled in the net. Realising it was not a shark, it was thrown back dead into the ocean. What a waste. Education is the key. It was not a targeted species and is protected.

On March 21, two pygmy sperm whales were killed off the coast of Siarfao Island, Phillippines. (read here my post)

Two new photos were released, showing a pygmy sperm whale calf, reportedly killed by dynamite fishing. The injuries are allegedly from dynamite fishing.

Dynamite fishing, which involves the use of explosives to stun and instantly kill fish, is often used by fishermen looking for an easier and faster way of catching fish.

The explosives are usually improvised. They are commonly plastic bottles filled with explosive nitrate and diesel.It’s possible that bigger capitalists, perhaps even foreign ones, are funding the fishermen.

Pygmy Sperm Whale in Captivity - Minamichita Beachland

There are very few cases in which this species has been held in captivity. A handful of these instances have occurred in Japan [including one at Marine Pia and] at the Minamichita Beachland marine park of Shizuoka, Japan.

On April 7, 2013 this individual male was found stranded in Kosai of the Shizuoka prefecture and brought to Minamichita Beachland for care. It is unclear whether the intent was for rehabilitation and release or permanent housing. At the time of discovery, he was 1.8 meters in length and assumed to be a juvenile. He was kept in the same enclosure which houses Beachland’s two finless porpoises, fish, rays and turtles.

After a few weeks, medical examination revealed that he had lost 6 kg since the stranding and had been suffering from parasitic infection. Veterinary staff planned to increase his food intake and administer de-worming medicine. A few days later (28 days after coming into the park’s care) he passed away.

                                       Pygmy Sperm Whale

                                        (Kogia breviceps)

is one of the three species in the sperm whale family (Dwarf sperm whale,Sperm whale) they are rarely sighted at sea and not much information is known about them. they are about 4ft in length at birth and can grow to 11 feet at maturity.

NOAA’s DNA database helps identify orca kill

Thanks to the NOAA’s collection of more than 140,000 tissue samples taken from marine mammals and sea turtles, we can now add another species to the list of killer whales’ potential prey: pygmy sperm whales.

During an NOAA Fisheries marine mammal survey last year, researchers witnessed a pod of orca make a kill roughly 200 miles off the coast of Central California. While the researchers did not arrive at the scene quickly enough to identify the prey by sight, they were able to recover the prey’s heart and lungs.

The tissue samples were taken back to the Marine Mammal Genetics Group at the Southwest Fisheries Science Center in La Jolla, California. There, DNA samples were extracted from the tissues and their genetic sequences compared to the computerized database of other DNA samples. This allowed the team to identify the orca kill as a pygmy sperm whale - the first confirmed case of killer whales preying on this particular species.

The NOAA’s research sample collection has provided invaluable information in the past. It was this collection that allowed researchers to discern genetically distinct ecotypes of killer whales and genetically distinct populations within those ecotypes - the endangered Southern Residents, for example. Another project helped assess genetic differences in different populations of bowhead whales; another helps identify the remains of marine organisms that have become entangled in fishing nets, which helps researchers track and protect endangered species and monitor their status. A current project hopes to identify a new species of beaked whale based on the remains of stranded individuals found in Alaska and Japan.

These projects show the necessity of collecting a wide range of tissue samples from individual animals and the importance of maintaining a DNA database for research purposes.

anonymous asked:

What animal is the scariest according to you? What's your biggest phobia?

Octopuses, squids, snails, worms, and similar creatures weird me out. I used to think sperm whales were scary as well, but then I found this picture of a pygmy sperm whale:

Such a precious baby!!

As far as “proper” phobias go, I have trypophobia (a fear of clusters of small holes). Apparently it’s a fairly common phobia to have. I’d like to be able to read more about it, since I think it’s interesting - and quite bizarre - to be so frightened and repulsed by just a picture of something that isn’t even dangerous in itself, but I am never ever googling that shit. I even feel a bit uneasy thinking about it. I need to look at some more baby animals now….

The Sperm Whale

The sperm whale (Physeter macrocephalus) is a marine mammal species, order Cetacea, a toothed whale (odontocete) having the largest brain of any animal. The name comes from the milky-white waxy substance, spermaceti, found in the animal’s head.
The sperm whale is the only living member of genus Physeter. The now outdated synonym Physeter catodon refers to the same species. It is one of three extant species in the sperm whale superfamily, along with the pygmy sperm whale and dwarf sperm whale.
