Daily fish fact #380

Dwarf lanternshark!

It is the smallest shark species in the world, only reaching a maximum length of 20 cm (8 inches)! They live rather deep at 280 to 440 meters (928-1 440 feet) and have light-emitting organs along their sides.

Uncharismatic Fact of the Day

Can I offer you a dwarf lanternshark in this trying time? This species of shark is the smallest in the world, at only 20 cm (8 in) long, and is found at depths of 283–439 m (928–1,440 ft). The dwarf lanternshark gets its name for its ability to produce light from a series of f light-producing photophores along its back, which may help it to attract prey or disorient predators.

If you send me proof that you’ve made a donation to UNRWA or another organization benefiting Palestinians, I’ll make art of any animal of your choosing.

kirbyssharkfacts i am feeling down. will you give me a kirbys shark facts?

sorry to hear you're feeling down anon, but i hope this fact will help cheer you up! did you know some sharks can glow in the dark? bioluminescence has been documented in multiple shark species: the kitefin shark, blackbelly lanternshark, and southern lanternshark.

the exact purpose of this bioluminescence is unknown, but scientists have made several hypotheses. it’s possible that the sharks use this to communicate with each other, to disguise themselves when hunting prey or evading predators, or to illuminate the ocean floor when searching for food. a research paper on this subject was published in the frontiers in marine science journal in 2021, which you can find here if you're interested!

[Image ID: Digital art of the ventral view of a dwarf lanternshark, a small tan shark with rounded fins and black underside. Its underside is speckled with blue spots of bioluminescence. It is on a background of dark blue with a light blue cloud and more blue spots of bioluminescence like stars. /End ID]

here's my full piece for this year's @swimonzine! we raised $685 for shark conservation this year. the zine, which includes over 100 illustrations of 40+ shark species, is still available for $1+ here, and all proceeds go to finfree.org

the dwarf lanternshark is credited to being the smallest shark in the world. they’re even smaller than a human hand, growing to be around 6 and a half inches long. but, the elusive american pocket shark is smaller, measuring in at 5.5 inches long.

jan 18 - dwarf lanternshark

this is the smallest species of shark at the size of a human hand! apparently they are in a group called the dogfish sharks and i think that’s very cool. like have you seen those videos of divers petting sharks? they act like dogs. it’s so cute. now we have dog shark. i don’t think that has anything to do with it.

all lantern sharks are capable of producing light! they are GLOWY fish! i love that deep sea animals just decide “oh actually. i think we will all just light up.” it makes the world a better place. in the draft of this i put an all star lyric here but i don’t think that needs to exist.

lots of fish have a tactic of having a lighter colored belly and a darker back—this is to make fish below them see the bright waters and assume they blend in, and vice versa for the fish above it. except this guy just straight up has light. overachiever. i love you guy. they look so goofy.

rating: 10/10. so Weird. looks like hes going to tell me hes neil cicierega on his alt account

how many sharks fit in a water tower?

well, now i have to know.

average water tower tank hold: 1000000lb/ 119826.43 gal

most common shark: blue shark (250lb/ 10ft on average)

you could fit about 4000 sharks in a water tower, but they would be crammed together and wouldn't survive. in order for them to survive, (not for very long because i can't imagine a water tower regulates it's oxygen and most sharks need salt water anyways.) you could only hold about 1333 average sized blue sharks in a water tower without immediate death.

however, there are smaller species of shark. the dwarf lanternshark is 8 inches and 2 pounds on average. it is a deep water animal so it wouldn't survive for very long in the low pressure of the water in addition to oxygen and salt.

also dwarf lanternsharks are bioluminescent!

you could fit 666666.7 dwarf lanternsharks in a water tower you can fit 222222.2 dwarf lanternsharks in a water tower without immediate death.

maybe. in addition to the previous issues i mentioned i'm not sure how you would get those sharks up there. and since they don't have room for food they would probably kill each other. i got all my information from google so- it's most likely wrong, and my math and logic here are real bullshit. i'm no mathematician and i'm failing in the subject so don't go telling your friends how many sharks you can fit into a water tower as a fact.

You know what it's time for?

WEIRD SHARKS THAT'S WHAT IT'S TIME FOR

(IDs are in the image descriptions)

Pocket Shark

Pocket sharks are named for two small pocket glands appearing behind their pectoral fins. These glands are theorized to be luminous. Pocket sharks look like tiny, tiny sperm whales.

Angular Roughshark

Also called the pig-faced shark or the pig fish, angular roughsharks grow to be about 3 feet 4 in long on average. I personally think they're more bat-faced.

Goblin Shark

Found in the deep sea, goblin sharks are known for being able to extend their jaws like a grabber tool made of teeth. Wikipedia says that these sharks' "flabby bodies" suggest that they are sluggish in nature.

Cookiecutter Shark

The cookiecutter shark only grows to about 20 inches in length, but that doesn't stop it from biting into orcas, great whites, or humans. It suctions onto its meal with its lips and then goes to town. It removes perfect circles of flesh, hence its name.

Wobeggong Shark

Wobeggong refers to twelve species of carpet shark, so-named for their resemblance to a shag rug. They dwell on the bottom of the sea floor and wait for smaller fish to swim nearby.

Swell Shark

Swell sharks like to hide in crevices of algae-covered rocks, waiting for prey to swim by. They are so named not because they're really swell (though they are) but because as a defense mechanism, they can swell up to double their size by swallowing sea water.

Greenland Shark

The Greenland shark has high concentrations of urea in its body. It is theorized to have a lifespan of 250 to 500 years, and it can grow up to 23 feet long. Greenland sharks have been found with moose and reindeer in their stomachs. Because of the shark's toxic levels of urea, its flesh must be fermented or otherwise treated before consumption.

Viper Dogfish

Like the goblin shark, the viper dogfish's jaws can protude from the rest of its head, though its coloring means the viper dogfish looks significantly more Xenomorphish when doing so. This small shark is a member of the lanternshark family, and its underside glows.

Pointy-Nosed Blue Chimaera

Also know as the abyssal ghostshark, this deep sea shark has a venomous spine on its dorsal fin used for defense.

Genie's Dogfish Shark

Genie's dogfish shark is a small species found in the gulf of Mexico and the west Atlantic Ocean. It has real life anime eyes.

Ninja Lanternshark

The ninja lanternshark is a small bioluminescent shark. It is all black except for white markings around its eyes and mouth. It reaches about a foot and a half in length.

Frilled Shark

The frilled shark is sometimes called a living fossil, as it is basically unchanged in the past 80 million years. They are named for their teeth, which each have three points.

Epaulette Shark

Epaulette sharks are named for the large spots behind their pectoral fins. These sharks frequently visit tidal pools and have adapted to long periods of oxygen deprivation by shutting down non-essential neural functions. Epaulette sharks often "walk" with their fins on the sea floor rather than swim.

Horn Shark

Similar to the epaulette sharks, horn sharks like to walk on the sea floor with their fins. However, these sharks have sharp spines to deter predators.

This Ridiculousness

A prehistoric shark, helicoprion lived 20 million years ago and was apparently part buzzsaw. A fossil unearthed in Idaho in 2014 showed that these sharks had no teeth in their upper jaw, and a whorl of teeth in their lower jaw. It's a shame Junji Ito wasn't introduced to this shark during the writing of Uzumaki.
