Crustacean Priests, Tide-Makers and Shadow-Eaters: 9 Pinches of Crab Folklore

Crabs are usually the harmless crustaceans you expect to see in rockpools (or if they're unfortunate, the market.)  That said, many of the crabs in folklore could do far worse than pinch an errant toe if angered.  Let's take a look at...

  • Kanibōzu, the Crab Priest
  • Carcinus (or Karkinos) and Hercules
  • Tambanokano, the Crab That Hunts the Moon
  • Pusat Tasek, the Crab in the Sea's Navel
  • Heikegani, Samurai Crabs
  • The Shapwick Monster
  • The Island-Like Saratan (or Zaratan)
  • Nkala, the Shadow-Eating Crab
  • Zipacna and the Counterfeit Crab

Kanibōzu, the Crab Priest

The kanibōzu of Japan is a sneaky crustacean with a religious bent, of a sort.  They are said to disguise themselves as priests, monks or pilgrims and take up residence in temples with don't have a head priest looking after them.  Once established, they begin harassing locals... and eating any priests that get in their way. 

One such kanibōzu is said to have haunted Chōgen-ji Temple in Manriki, Yamanashi.  The story goes that one day a 10ft tall pilgrim strode up to the temple and asked the head priest a riddle: “I am eight-legged, able to sidle at will, and heavenward-eyed; what am I?”  When he failed to guess the answer, the pilgrim killed and ate him, then repeated the same exchange with every priest until the temple was left empty.

Years later, a wandering monk called Hōin visited the temple - some versions of the story claim that he wanted to challenge the creature, while others say that he was unaware of the danger.  Either way, the kanibōzu emerged as Hōin tried to sleep and posed his riddle - only for the wily monk to answer that he was a crab.  

Guessing the riddle shattered the creature's disguise and it scuttled to a local pond to escape, but Hōin shattered its shell with a blow from his staff - when the locals drained the pool, they found the dead crustacean and the bones of the many priests it had eaten!

Carcinus (or Karkinos) and Hercules

You've probably heard of the Hercules or Heracles - but if you've not, he was a mighty Greek demigod who was despised by the goddess Hera and (through her machinations) was set a number of "impossible" tasks.  One of those tasks was to slay Lernaean Hydra, a multi-headed monster that would regenerate heads even as they were removed.  

Supposedly at the behest of Hera, the giant crab Carcinus attempted to distract Hercules during the fight, snapping at his foot while he fo8ught the hydra.  This attempted intervention cost Carcinus dearly, as Hercules simply crushed it beneath his foot - though in some versions of the tale, Hera did reward the flattened crustacean with a place amongst the stars as the constellation "Cancer!"

Tambanokano, the Crab That Hunts the Moon

From Philippine folklore comes the colossal crab Tambanokano, a creature said to be the child of the Sun and Moon.  Thanks to its prodigious size, this crustacean is said to cause a flash of lightning when opening or closing its eyes.  It also causes the low tide when it leaves its seabed burrow and water rushes in, with a corresponding high tide when it returns.  The movements of Tambanokano can also cause powerful waves.

Legend has it that sometimes Tambanokana (who inherited the volatile temper of the Sun) becomes enraged and attempts to eat the Moon - but that he can be driven away by the noise created by brave humans shouting and striking gongs as he approaches his intended prey!

Pusat Tasek, the Crab in the Sea's Navel

Malay folklore also features a giant crab that lives in the massive whirlpool Pusat Tasek or the Naval of the Ocean.  The vortex is said to contain a massive magical tree called Pauh Janggi that provides a refuge for the mighty crustacean... and like the legend of Tambanokano, the tides themselves are said to be caused by the crab leaving its den to forage in the ocean!

Heikegani, Samurai Crabs

Heikegani (Heike crab) are a species of crustacean native to Japan, where evolution seems to have played an interesting trick - viewed from above, their shells have a passing resemblance to a scowling human (or samurai-masked) face.

Their looks have connected them with the 1185 Battle of Dan-no-ura, a decisive naval engagement in which many Taira clan (sometimes known as Heike) samurai were slain or drowned.  Legend has it that the spirits of the samurai found new homes in the crabs, warping their shells in the process!

The Shapwick Monster

The village of Shapwick in Dorset, England, is around 16km from the harbor at the coastal town of Poole... which makes this local bit of folklore rather strange.

The story goes that in 1706 a fishmonger was making the trip between Poole and Bere Regis, passing through the village of Shapwick on the way.  Unbeknownst to the fishmonger, one of the items on his cart slipped free and escaped onto the road, where it was encountered by one of the villagers.

The creature was armored and, despite only being around 30cm across, raised two claws in a threat before scuttling away sideways.  Confronted with the unknown, our unwitting hero roused the village and they descended on it with clubs, torches and pitchforks - all to drive the monster (identified as such by a wise village elder) from their midst.

The mob had the creature at bay when the fishmonger returned, looking for his errant bit of merchandise.  The tale goes that he exclaimed "What's this - why are you all hunting my crab?"  He then scooped up the poor crustacean and left, laughing at the foolishness of the villagers.

The story spread (in 1841 Buscall Fox turned it into an illustrated poem) and eventually became a bit of local parlance - the expression "a Shapwick monster" became a Dorset saying for something to extraordinary to be explained.  Though the villagers of Shapwick were the victims of mockery for a time, a nearby farm is named "Crab Farm" in honor of the event!

The Island-Like Saratan (or Zaratan)

Somewhere between crab, turtle and whale, the saratan (Arabic for cancer or crab) dwarfs all of its inspirations.  

It shows up in "The Book of Animals" by Al-Jahiz from the 9th century, albeit in terms of ridicule.  Al-Jahiz relays the tales told by sailors of large "islands" (complete with trees) that would suddenly start swimming away when camping sailors began building up a fire on its back - potentially taking the sailors with it.  Suffice to say, Al-Jahiz wasn't convinced by the stories.

It seems that the saratan was reimagined as a turtle in the Manual de Zoología Fantástica by Jorge Luis Borges and Margarita Guerrero.

Nkala, the Shadow-Eating Crab

A particularly malignant crustacean is the nkala, a deadly creature from African folklore.  Described as being a four foot long crab with two hippo like heads (one at either end of its body) this creature kills human prey by consuming their shadow, with both heads going to work on it.  Even worse, a nkala can be bound to serve a sorcerer as a familiar - and assassin.

...to combine with this! (Aji Vinister Denistan)

A skilled ng'anga (shaman) can kill a nkala.  One method involves filling two duiker horns (one partially, one fully) with a medicine that includes the parts of a previously-slain nkala.  The ng'anga then leads a hunting team to the river in which it lairs, where the hunters take up hidden positions.  The ng'anga then blows across the top of the partially filled horn to create a whistle, which lures the nkala out... at which point the hunters emerge and perforate it with projectiles.  The noses, claws and other parts are removed and used to prepare more of the medicine, for next time it's needed!

Zipacna and the Counterfeit Crab

Did you know that Maya mythology features a dangerous god slain by a fake giant crab and a collapsing mountain?  The tale can be found in the Popol Vuh (or Book of the Council/Community) from the Kʼicheʼ Maya people of Guatemala.  

The story begins with the god Zipacna encountering 400 boys attempting to construct a large hut, but struggling with the massive tree they intended to use as the central support post.  The mighty Zipacna offered to help... and singlehandedly carried the log to the desired spot.

More subtle than this? (LIM ENG)

This display of physical power worried the 400, and they subsequently decided to kill Zipacna by treachery.  They asked him to help dig a hole for the post and when Zipacna was well below ground level, dropped the tree in on top of him.

Things were not as they seemed, however.  Zipacna had overheard their plotting and dug a side tunnel in which he avoided being crushed.  A few days later, he emerged from the ground and cast down the hut, crushing all 400 of his would-be murderers.

The story doesn't end there.  The hero twins Hunahpu and Xbalanque decided to kill Zipacna in retaliation (which doesn't seem very fair really.)  Since they knew that their quarry feasted on crabs and fish, they constructed a giant fake crab to lure him to his doom.  They used materials gathered from the forest (including a bromeliad flower as a face) to produce their counterfeit crustacean, placed it at the base of a mountain and then sought out Zipacna.

The hungry god was searching for crabs at the rover's edge when they found him, and a tale of a large crab was enough to lure him to the trap.  With his suspicion dulled by hunger, Zipacna attempted to capture the crab... only for Hunahpu and Xbalanque to collapse the mountain on him!
