The Can-do Pelican Eel

The pelican eel, also known as the gulper eel (Eurypharynx pelecanoides), are the only known species of eel in the family Eurypharyngidae. They are found exclusively in the deeper parts of the water column, from depths of 500 up to to 3,000 m (1,600 to 9,800 ft), but are distributed throughout all the world's oceans.

The gulper eel is perhaps most famous for its unique body shape. Like many deep-sea fish, this species is highly adapted to its environment; maximum energy efficiency is the highest priority. To that end, the pelican eel has a large head, and a jaw estimated to be quarter of the total length of its body. The jaw is loosely hinged, meaning that gulper eels can open their mouths extremely wide. The rest of the eel, in contrast, is quite slender and long, about 0.75 m (2.5 ft) in length on average. Most individuals are black--so black, in fact, that they only reflect 0.5% of light; perfect for hiding from potential predators.

Although they look skinny, E. pelecanoides can expand their stomachs to hold prey much larger than themselves. Their primary prey consists of crustaceans and cephalopods, though they may feed opportunistically on other fish. Because it is so well camouflaged, it uses bioluminescent organs on the tip of its tail to attract prey. Gulper eels themselves are preyed upon by lancetfish and other larger deep-sea fish. To deter predators, they will gulp down a large amount of water; this stretches the loose skin around their head and throat, and inflates them to several times their usual size.

Because of their remote location, the breeding habits of gulper eels are relatively unknown. However, it is believed that smell plays a large part in attracting a mate, as pelican eels have highly developed olfactory organs. Like other eels, they're born as tiny, transparent larvae in a state known as the leptocephalus stage. At this stage, they do not have any red blood cells. Researchers aren't sure how long it takes gulper eels to become fully mature, or how long they live, but many believe that adults die shortly after mating.

Conservation status: The population size of E. pelecanoides has not been assessed, and thus the IUCN has not made a determination on its status. The greatest threat for this species is deep-sea trawling, which frequently brings up gulper eels as by-catch.

““The Great Pacific Garbage Patch can now be cleaned,” announced Dutch entrepreneur Boyan Slat, the wonderkid inventor who’s spent a decade inventing systems for waterborne litter collection.

Recent tests on his Ocean Cleanup rig called System 002, invented to tackle the 1.8 trillion pieces of plastic pollution, were a success, leading Slat to predict that most of the oceanic garbage patches could be removed by 2040.

Intersections of ocean currents have created the massive floating islands of plastic trash—five slow-moving whirlpools that pull litter from thousands of miles away into a single radius.

The largest one sits between California and Hawaii, and 27-year-old Slat has been designing and testing his systems out there, launching from San Francisco since 2013.

GNN has reported on his original design for the floating device, but his engineering team improved upon it. System 002, nicknamed “Jenny,” successfully netted 9,000 kilograms, or around 20,000 pounds in its first trial.

It’s carbon-neutral, able to capture microplastics as small as 1 millimeter in diameter, and was designed to pose absolutely no threat to wildlife thanks to its wide capture area, slow motion, alerts, and camera monitors that allow operators to spy any overly-curious marine life...

Slat estimates ten Jennies could clean half the garbage patch in five years, and if 10 Jennies were deployed to the five major ocean gyres, then 90% of all floating plastic could be removed by 2040.” -via Good News Network, 10/19/21

while everyone's rightfully talking about oppenheimer and its flaws regarding the erasure of japanese and native american voices regarding nuclear testing and detonations, i'd like to bring up the fact that pacific islanders have also been severely impacted by nuclear testing under the pacific proving grounds, a name given by the US to a number of sites in the pacific that were designated for testing nuclear weapons after the second world war, at least 318 of which were dropped on our ancestral homes and people. i would like if more people talked about this.

important sections are bolded for ease of reading. i would appreciate this being reblogged since it's a bit alarming how few people know about this.

--

in 1946, the indigenous peoples of pikinni (the bikini atoll) were forcibly relocated off of their islands so that nuclear tests could be run on the atoll. at least 23 nuclear bombs were detonated on this inhabited island chain, including 20 hydrogen bombs. many pasifika were irreversibly irradiated, all of them were starved during multiple forced relocations, and the island chain is still unsafe to live on despite multiple cleanup attempts. there are several craters visible from space that were left on the atoll from nuclear testing.

the forced relocation was to several different small and previously uninhabited islands over several decades, none of which were able to sustain traditional lifestyles which directly lead to further starvation and loss of culture and identity. there is a reason that pacific islanders choose specific islands to inhabit including access to fresh water, food, shelter, cloth and fibre, climate, etc. and obviously none of these reasons were taken into account during the displacements.

200 pikinni were eventually moved back to the atoll in the 1970s but dangerous levels of strontium-90 were found in drinking water in 1978 and the inhabitants were found to have abnormally high levels of caesium-137 in their bodies.

--

i'm going to put the rest of this post under a readmore to improve the chances of this being reblogged by the general public. i would recommend you read the entirety of the post since it really isn't long and goes into detail about, say, entire islands being fully, utterly destroyed. like, wiped off of the map. without exaggeration, entire islands were disintegrated.

--

as i just mentioned, ānewetak (the eniwetok atoll) was bombed so violently that an entire island, āllokļap, was permanently and completely destroyed. an entire island. it's just GONE. the world's first hydrogen bomb was tested on this island. the crater is visibly larger than any of the islands next to it, more than a mile in diameter and roughly fifteen storeys deep. the hydrogen bomb released roughly 700 times the energy released during the bombing of hiroshima. this would, of course, be later outdone by other hydrogen bombs dropped on the pacific, reaching over 1000 times the energy released.

one attempt to clean up the waste on ānewetak was the construction of a large ~380ft dome, colloquially known as the tomb, on runit island. the island has been essentially turned into a nuclear waste dump where several other islands of ānewetak have moved irradiated soil to and, due to climate change, rising seawater is beginning to seep into the dome, causing nuclear waste to leak out. along with this, if a large typhoon were to hit the dome, there would be a catastrophic failure followed by a leak of nuclear waste into the surrounding land, drinking water, and ocean. the tomb was built haphazardly and quickly to cut costs.

hey, though, there's a plus side! the water in the lagoon and the soil surrounding the tomb is far more radioactive than the currently contained radioactive waste. a typhoon wouldn't cause (much) worse irradiation than the locals and ocean already currently experience, anyway! it's already gone to shit! and who cares, right, the only ""concern"" is that it will just further poison the drinking water of the locals with radioactive materials. this can just be handwaved off as a nonissue, i guess. /s

at least 36 bombs were detonated in the general vicinity of kiritimati (christmas island) and johnson atoll. while johnson atoll has seemingly never been inhabited by polynesians, kiritimati was used intermittently by polynesians (and later on, micronesians) for several hundred years. many islands in the pacific were inhabited seasonally and likewise many pacific islanders should be classified as nomadic but it has always been convenient for the goal of white supremacy and imperalism to claim that semi-inhabited areas are completely uninhabited, claimable pieces of terra nullius.

regardless of the current lack of inhabitants on these islands, the nuclear detonations have caused widespread ecological damage to otherwise delicate island ecosystems and have further spread nuclear fallout across the entirety of the pacific ocean.

--

while the marshall islands, micronesia, and the surrounding areas of melanesia and polynesia were (and still are) by far the worst affected by these atrocities, the entirety of the pacific has been irradiated to some extent due to ocean/wind currents freely spreading nuclear fallout through the water and air. all in all, at least 318 nuclear bombs were detonated across the pacific. i say "at least" because these are just the events that have been declassified and frankly? i wouldn't be shocked to find out they didn't stop there.

please don't leave the atomic destruction of the pacific out of this conversation. we've been displaced, irradiated, murdered, poisoned, and otherwise mass exterminated by nuclear testing on purpose and we are still suffering because of it. many of us have radiation poisoning, many of us have no safe ancestral home anymore. i cannot fucking state this enough, ISLANDS WERE DISINTEGRATED INTO NONEXISTENCE.

look, this isn't blaming people for not talking about us or knowing the extent of these issues, but it's... insidiously ironic that i haven't seen a single post that even mentions pacific islanders in a conversation about indigenous voices/voices of colour being ignored when it comes to nuclear tests and the devastation they've caused.

Gummy squrrel

A bizarre gelatinous creature that resembles a half-peeled banana was spotted by researchers in the Pacific Ocean. The creature, known as a gummy squirrel (Psychropotes longicauda), is actually a sea cucumber and was around 2 feet (60 cm) long.
