CRINCH! #CrabOfTheDay for 01/31/2017: Palinurus mauritanicus, The Pink Spiny Lobster (The Rose Langostine in Europe) is a species of deep water spiny lobster found in the Eastern Atlantic Ocean and Mediterranean Sea. This ‘clawless’ critter has a carapace with two brutal-looking rows of forward-directed spines. The peduncle, or the base segment of the antenna, is particularly stout. Living a relatively long time, (up to 25+ years!) P. mauritanicus is found on the seafloor at the edge of the continental shelf at depths deeper than 200 m. Though Pink Spinys scavenge dead muck, they’ll also lay into a meal of live mollusks, starfish, urchins, and any other crustaceans which can’t escape them!

CRINCH! #CrabOfTheDay for 02/01/2017: Zenopontonia rex, known as the Emperor Shrimp, is a species of Indo-Pacific Caridean/family Palaemonidae shrimp. This amazing little guy lives commensally on a number of hosts, including the sea slug Hexabranchus. Z. rex, still widely known by its junior taxon: Periclimenes imperator, seems to be a rare case of possible ontogenetic host switching, living on sea cucumbers and, occasionally, on sea stars (echinoderms) as juveniles, and on nudibranch sea slugs (molluscs) as adults! With the regal coloration of this animal and its penchant for riding slug “mounts,” It’s easy to make the comparison to an Emperor, atop his steed!

CRINCH! #CrabOfTheDay for 02/03/2017: Atergatis integerrimus, or The Red Egg Crab is a fantastic reef dweller from Mauritius, Zanzibar, India, the Philippines, Hong kong, Japan, Taiwan, and Singapore. Possessing an ovaloid, brilliantly red carapace and impressive claws- this family Xanthidae crab usually hides under larger rubble or in reef holes as it isn’t very fast-moving. Divers are generally discouraged from handling these crabs and they CERTAINLY shouldn’t be eaten as they contain a TON of paralytic shellfish poison!

CRINCH! #CrabOfTheDay for 02/04/2017: Chaceon crosnieri, or Crosnier's Crab is a spine-sided family Geryonidae species of crab found ONLY around Madagascar, at the 400 m to 800 m depth zone. Crosnier's Crabs have a rather unique ‘thorny crown’ shape, and are very rarely seen in the wild. Named after crazy-ass crab collection curator Alain Crosnier, (say that 10 times fast!) this species was first catalogued by Raymond B. Manning (American carcinologist/alpha taxonomist) and Lipke Bijdeley Holthuis, (Dutch carcinologist) arguably, the two GREATEST modern carcinologists!

CRINCH! #CrabOfTheDay for 02/04/2017: Discorsopagurus schmitti, or The Tube Worm Hermit Crab is a CRAZY North-Pacific (Alaska, Canada, and Washington to Japan) species of Superfamily Paguroidea/ Family Paguridae hermit that lives its life in the empty, fixed tubes built by the polychaete worm Sabellaria cementarium. This strange, sessile way of life is made possible by two factors:

First, this small hermit has an abdomen that is not coiled but is a straightened cylinder shape- perfect for fitting in old worm tubes.

Second, D. schmitti employs four different feeding techniques: antenna fanning, tube/body-trapping, using its claws to catch drifting particles, and scraping the surrounding sea material around its chosen tube.

In its natural habitat, this crab inhabits only empty, fixed tubes, though in its post-larval stages it prefers discarded gastropod shells. The behavior of megalopae and juveniles seems to testify to the shell-dwelling ancestry of D. schmitti.

CRINCH! #CrabOfTheDay for 02/06/2017: Porcellana platycheles, called The Broad-Clawed Porcelain Crab, is a small family Porcellanidae species, (no bigger than 15 millimeters!) in the Eastern North Atlantic Ocean and Mediterranean Sea. This filter feeder, obviously named for its broad, flat, chelae, is typically not that great with other crustaceans in a given reef or aquarium. Sometimes called the “Hairy Broad Crab,” P. platycheles typically is grayish brown to dirty yellowish and white in color.

CRINCH! #CrabOfTheDay for 02/13/2017: Platypodia granulose, or the “Curry Puff Crab,” more officially called the Granulated Flatfoot Crab or the Crested Reef Crab is a yellowish/orange-ish species of family Xanthidae crab, found on the East Coast of Africa, Madagascar, Red Sea, India, Maldives, Samoa, Palau, Australia, New Caledonia, China, Tahiti, Hawaii and Japan. This Nipper is thickly covered with granules, giving it the appearance of a ‘fried curry-filled won ton.’ Only its eyes and claw tips (being red) belie its sand-colored camouflage scheme.

CRINCH! #CrabOfTheDay for 02/14/2017: Notomithrax ursus, known as The Hairy Seaweed Crab, is a family Majidae spider crab, found ONLY in Australia and New Zealand. Though primarily agaeovores, these wooly monsters will also eat small gastropods, isopods, amphipods, and decapods, bryozoans, polychaetes, sponges, ostracods, nemerteans, copepods, and bivalves; in other words, LOTSA tiny plants and animals! N. ursus, also called “Seaweed Bears,”camouflage their body by attaching pieces of seaweed and algae to the curved setae that cover their body.

The types of algae most preferred as masking material were branched algae such as Halopteris spicigera and Corallina officinalis.

CRINCH! #CrabOfTheDay for 02/15/2017: Episesarma mederi, called The Thai Vinegar Crab is a thick little Indo-Pacific family Sesarmidae species of mangrove/mudflat terrestrial crab. Thai Vinegars primarily feed on leaves, and create burrows in the mud adjacent to tree roots. This aerates the landscape, and removes a lot of potentially acidic biomass from the environment- keeping it from becoming TOO brackish. When the water level rises too quickly- these crabs can very easily climb the same mangroves they live under!

Thai Vinegar Crabs, like other Sesarmine crabs, are known to be consumed as food in several cultures- often preserved in black vinegar and salt; the perfect topping for a Thai papaya salad!

This bright filter feeder lives manly on long swaying corals including Chain Corals, Sea Pens, and Gorgonians. Called ‘Four-Leaf Smooth Crabs’ (四葉光滑瓷蟹) in Japanese, these crustaceans frequently fall victim to Aporobopyrus dollfusi- a bophyrid isopod parasite.

CRINCH! #CrabOfTheDay for 02/19/2017: Platyactaea setigera, or The Bristled Rubble Crab is lumpy crapace’d species of BRIGHT RED family Xanthidae crab found in The Gulf of Mexico through Central America! This Western Atlantic snapper ekes out a living in Epibiotic fashion: ie; it lives on the surface of
molluscan and other shells, not necessarily hurting them, but definitely jacking meals from them. More of a social parasite really! When shoals of chump-ass shellfish aren’t available, OR if the crab decides for whatever reason to leave, it can be found among reef rubble, at the 1-65 meter zone.

CRINCH! #CrabOfTheDay for 02/20/2017: Eurytium limosum, or The Broadback Mud Crab is a terrestrial species of intertidal mangrove crab, found in The Gulf of Mexico, Caribbean Territories, and Continental US- namely Puerto Rico. Belonging to a genus with only four species, this family Panopeidae crab is generally found living in the roots of the Red Mangrove. (Rhizophora mangle) Although its diet includes some plant material, E. limosum is primarily predatory and consumes other crabs, polychaetes, ostracods, bivalves, and snails.

CRINCH! #CrabOfTheDay for 02/21/2017: On Shigeru Mizuki Road, (named for Japan’s most beloved manga author and historian) there are 133 bronze statues of characters from his long-running story “GeGeGe no Kitaro” (as well as a few other yokai, or Japanese folklore creatures, both evil and friendly) in the town of Skaiminato, a small crab fishing port in Tottori Prefecture.

One of these character statues is of “Kani Bouzu,” a CRAB PRIEST! This gigantic crab is as big as two tatami mats and lives disguised as a priest at a temple in Kai domain, present Yamanashi Prefecture. People were petrified of being jacked by Kani Bouzu as he was prone to eating any other visiting priests one after another. Eventually in a sphinx-like game of riddles, a crafty Nomadic Monk defeats Kani Bouzu causing him to commit suicide or flee or something. Later on, a pond behind the temple is drained, and the bones of everyone killed by Crab Priest were found. GROSS!

Shigeru Mizuki may have based this character on an old legend in a similar vein, the “Kani-Oni, or DEMON CRAB,” or the Hekigani (ヘイケガニ) or "Samurai Ghost Crabs."(also an actual crab, Heikeopsis japonica!)

CRINCH! #CrabOfTheDay for 02/22/2017: Carcinoplax confragosa, or The Philippine Rough Crab is family Goneplacidae species found in Indo-Pacific waters, primarily the Philippines. Possessing a ball-shaped, granulate carapace covered with long, thin, soft setae, C. confragosa is a rather capable omnivore- capable of jacking living or dead meals of opportunity with its long, black-tinted claws. The Philippine Rough Crab was first studied and catalogued by Crabstar Carcinologist Mary J. Rathbun, aboard the Steamer Albatross during its 1907 – 1910 Philippine expeditions.

Fun Fact: “confragosa” means rough and rugged and in this case, and refers to the coarsely wrinkled and bumpy upper surface of C. confragosa’s carapace.

CRINCH! #CrabOfTheDay for 02/25/2017: Chirostylus sandyi, or The Spider Squat Lobster is a family Chirostylidae “Anomuran Crab” (false crabs) found in the Philippine Sea. This somewhat recent rediscovery (first described in 2009 by Baba) has a tiny carapace with spider-like long legs, colored brick red with yellow lines, and complimented by white spots. C. sandyi lives on deep-water corals and rocky reefs at the 15-40 meter depth range. Feeding primarily on zooplankton, this odd-looking critter, as well as hermit crabs and standard squat lobsters, are considered more distant cousins of “Brachyuran” or true crabs.

CRINCH! #CrabOfTheDay for 03/01/2017: Nursia plicata, The Persian Purse Crab, is a family Leucosiidae Tropical Indo-West Pacific species known mainly for its presence in Iranian Persian Gulf waters. This subtidal leucosiid has an angular, spined “maple leaf” shaped body with large, apparent chelipeds, roughly about 1 1/4 times the length of its carapace. These, and related leucosiid crabs constitute one of the commonest but least known brachyuran taxa in the Indo-West Pacific region. Though studied by generations of taxonomists starting with Bell (1855), they largely remain a source of systematic and nomenclatural confusion.

(La Pesca, Tamaulipas to Rio San Pedro, and Campeche.) Frequently confused with Uca virens, Uca burgersi Holthuis, or Uca speciosa; this rather indistinct crab requires habitual expert observation to discern it from its close cousins. As is the case with other fiddlers, M. marguerite males typically have an enlarged right claw, used for mate attraction.

CRINCH! #CrabOfTheDay for 03/05/2017: The Spanish Freshwater Crab, or Potamon ibericum is a Eurasian species of semi-terrestrial crab found adjacent to The Mediterranean Sea, Greece, both sides of the Black and Caspian Seas, Southern France, and Parts of Eastern Europe and Russia. Fossil examples, labeled "Potamon antiquum" have been found in Pleistocene age sediments in northern Hungary. Also called the Iberian Freshwater Crab, The Crimean Freshwater Crab, and The Cagne River Crab, this species feeds on land, but returns regularly to the water, and can survive short periods of drought in burrows and under stones.

Classified as ‘near threatened’ on the IUCN Red List, as "it is possible that populations of P. ibericum in parts of its range might be in danger of extirpation in the future, especially those on islands or near centers of human population on the mainland"
