Scorpio maurus palmatus (Ehrenberg, 1828)Scientific name: Scorpio maurus palmatusCommon name: Israeli gold scorpion, large clawed scorpionFamily: ScorpionidaeDistribution: Algeria, Egypt, Libya, Sudan, Israel and JordanVenom strength: Not considered medically importantBehaviorThe Scorpio maurus palmatus (Scorpio means scorpion, maurus means dark or obscure) is a very defensive scorpion species, unlike many will think they are not prone to sting (unless provoked). They rely on their powerful chelae to withstand an opponent. They grow in length to about 60 mm (2,4") on average, weighing about 2 - 3 grams. They are known for being excellent diggers, making burrows up to about 40 cm (16") (average) in depth, the bottom of the burrow usually enlarged. Although many people consider it a desert species, and therefore giving the scorpion a desert-like environment, Scorpio maurus palmatus can't be kept very easily in a dry environment. Which will be explained in the housing section below.They are usually found in deserts but also dry forests. At some areas it's possible to find multiple specimens living close to each other, each having their own burrow. They are not known for being very communal, males and females are only found together during mating season.SexingScorpio maurus palmatus is not really hard to sex. When a male and female are available the easiest and fastest way is by looking at the surface of the mesosoma. In males the surface looks matte, in females the surface looks glossy. This of course isn't the best way of sexing. Another difference is in the shape of the chela, especially the length of the fixed finger. In males the fixed finger in shorter than in females. Do note the length among the different Scorpio species can also be different.Like most scorpions males are more slender build than females.Pectine tooth count (PTC) is no good way in sexing Scorpio maurus palmatus, males PTC range = 9 - 11 while females PTC range = 7 - 11 teeth.The best way of sexing Scorpio maurus palmatus is by looking at the genital opperculum. Like all Scorpionidae the males have a more oval shaped genital opperculum and the females have a more heart-like shaped genital opperculum.Female chela:HousingScorpio maurus palmatus can best be housed in a deep enclosure, preferably with a deep layer of substrate. In order to keep the conditions optimal it's best to reproduce the dry- and rainy seasons found in their natural habitat. The dry season will range from October till June, the rainy season from Juli till September. During the rainy season on average a few centimeters of rain will fall daily, making the soil damped.The damped soil can be reproduced by adding water to the soil or by using a false bottom setup. Personally I prefer using a false water setup which gives a good range of humidity for the scorpion to dig to (humidity gradient). In order to trigger the digging, it helps to make a part of the top soil moist.Next to this the temperature should be reproduced, ranging from maximum temperatures of 18 - 35 *C (64 - 95 *F) and minimal temperatures from 8 to 25 *C (46 - 77 *F).The winter period (August to May) and summer period (June to September) can be reproduced by heating the enclosure during summer time and keeping the enclosure at a lower temperature during the winter time. Heating should occur from the top, because the scorpion will dig to avoid the heat a heat pad at the side of the enclosure might interfere with the natural behaviour.When heated from the top, the scorpion can dig to the appropriate depth where humidity and temperature are ideal.Egypt climate:Morocco climate:These conditions can only be reproduced using a relative large enclosure of at least 20 x 20 cm (8 x 8") ground space and a height of at least 40 cm (16"), if possible a higher enclosure would be better.The scorpions might drink from a shallow water dish.For start, a piece of wood or similar kind of hiding can be placed. Usually the scorpion will start making the burrow below this piece of hiding. Plants can be used to boost humidity but are not needed.Plants also can carry insects or can rot attracting mites and such. For those people who like to know the humdity levels, during the rainy season try to maintain an LV of about 70% while during the dry season a LV of about 40 - 50% would be fine.It is possible for one to see some pieces of the prey items at the entrance of the burrow, Scorpio maurus palmatus is known for keeping the burrow clean by pushing out the left overs. The burrow maintenance usually takes place during the rainy season. In this time the burrow may also be expanded.Looking at the amount of Scorpio maurus palmatus living close to each other in nature, it should be possible housing multiple specimens in a single enclosure.To make sure the chance of cannibalism will be low, an enclosure of at least 80 x 40 cm (32 x 16") ground space should be used.False bottom setupTo start, fill the bottom of the enclosure with a good layer of gravel. Place a hollow tube on the gravel-layer and fill the enclosure with the desired substrate. Through the fill tube; add water to the gravel-layer. Make sure to fill until half the gravel-layer is submerged. The water will seep up and through the substrate, ensuring that the substrate remains moist at all times. The only thing to take care of is to check the water level weekly and add more as necessary to keep it at the recommended level.Make sure during the dry-period, the substrate is dry and no water is added to the soil.FeedingScorpio maurus palmatus are known for being sit and wait predators, they forage mainly from the entrance of their burrow.They regularly feed during the day, with daytime activity after a good rain (early spring) might be a response to the sudden mass of great numbers of prey.In captivity Scorpio maurus palmatus feeds well on pinhead crickets, small roaches and those kind of prey items.Feed them once per week an appropriate size prey. Being sit and wait predators make sure to leave the prey item in their enclosure for one day before removing it.In nature these scorpions mainly feed on isopods, ants and beetles. They play a important role in 2 different food chains.1) Dry plant materials -> isopods -> Scorpio maurus palmatus2) Seeds -> ants -> Scorpio maurus palmatusBreedingScorpio maurus palmatus has proven to be hard to breed, this might be caused by their natural season changes which do not occur in captivity.Once a female does get gravid, it takes a pretty long time (average = 15 months) before possible scorplings are born.It does happen wild caught females give birth to scorplings in captivity, it has been difficult for most people to keep the scorplings alive (as can be read below). The best way of getting them to breed in my opinion is reproducing environmental conditions.This means a dry season of a few months and a rainy season. During the rainy season the soil should be made damp, making it possible for the scorpions to dig burrow more easily.Reproduction in nature takes place in the dry season, May and June. Males and females are found together in a single burrow in this time.Gravid females are visible from June to November, with scorplings living with their mom found from August forward.As soon as the rain season appears in November the scorplings disperse and create their own burrows.Raising the kidsA person I know had some scorplings (7 in total) of Scorpio maurus palmatus, which were born at a pet store.He bought the female scorpion including the offspring. The scorplings were placed in 3 groups.The female:Scorplings:Below his story zo far:
QUOTE
Group 1: 3 scorplingsGroup 2 and 3: 2 scorplingsThey were fed a buffalo worm twice a week. Normally they had a little fight once in a while over a prey-item.One day a scorpling of group 1 was found death, cause unknown. Group 3 was picked up by some one else.Not long after another scorpling was found death. To be sure all scorplings were placed separate.To try and maintain humidity, a corner of their enclosure was sprayed daily.They do seem to like digging, especially when the corner has just been sprayed.
As you can read the scorplings like to dig when the soil is moist. This is also found in nature.Scorplings disperse and dig their own burrow when soil moisture is high.This tiny part of information is crucial to get these scorplings to mature.Subspecies of Scorpio maurus and other Scorpio speciesAs most people will know there was only one species of Scorpio, namely Scorpio maurus, and many subspecies.Lourenco finally has taken a better look at the taxonomic position of Scorpio maurus subspecies and made some modifications which were really needed, raising some subspecies to species level and introducing 2 new Scorpio species from Cameroon and Sudan. Vachon (1952) already defined a number of characters, analysis of these characters confirmed that these were valid for the precise definition of true species. The species Lourenco has taken a look at all belong to the African Scorpio species. In my personal opinion this is a very positive beginning of what hopefully leads to a taxonomic system.The first new Scorpio species is called Scorpio savanicola (savanicola meaning savannah dweller).The second new Scorpio species is called Scorpio sudanensis.As can be seen in the picture below, most Scorpio maurus subspecies have a different sternum and genital opperculum, which can be the first sign of different species instead of different subspecies.I: Scorpio maurus "Senegal" - femaleII: Scorpio maurus hesperus - femaleIII: Scorpio maurus magadorensis - femaleIV: Scorpio maurus maurus - maleV: Scorpio maurus tunetanus - maleVI: Scorpio maurus tunetanus - femaleVII: Scorpio maurus palmatus - maleVIII: Scorpio maurus fuscus - femaleIX: Scorpio maurus fuscus - maleX: Scorpio maurus kruglovi - femaleXI: Scorpio maurus kruglovi - maleThe old taxonomic system of Scorpio maurus and all subspecies:Scorpio maurus (Linne, 1758)S. m. maurus (Linne, 1758) - Algeria, Morocco, TunisiaS. m. arabicus (Pocock, 1900) - Penisule ArabiaS. m. behringsi (Shenkel, 1949) - MoroccoS. m. birulai (Fet, 1997) - MoroccoS. m. fuliginosus (Pallary, 1928) - MoroccoS. m. fuscus (Ehrenberg, 1829) - Morocco?, Saudi-Arabia, Iraq, Israel, Jordan, Lebanon, Syria, Turkey, Yemen?S. m. hesperus (Birula, 1910) - MoroccoS. m. kruglovi (Birula, 1910) - Saudi-Arabia, Iran, Iraq, Jordan, Kuwait, Qatar, SyriaS. m. legionis (Werner, 1936) - Mauritanian SenegalS. m. mogadorensis (Birula, 1910) - MoroccoS. m. occidentalis (Werner, 1936) - Mauritanian SenegalS. m. palmatus (Ehrenberg, 1828) - Algeria, Egypt, Libya, Sudan, Israel, JordanS. m. propinquus (Simon, 1872) - SyriaS. m. punicus (Fet); old name: S. m. tunetanus (Birula, 1909) - Algeria, Libya, Morocco, TunisiaS. m. stemmli (Shenkel, 1949) - MoroccoS. m. townsendi (Pocock, 1900) - IranS. m. trarasensis (Bousisset & Larrouy, 1962) - AlgeriaS. m. weidholzi (Werner, 1929) - MoroccoS. m. yemmensis (Werner, 1929) - YemenAfter Lourenco's work in 2009:New taxonomic system of Scorpio species and subspecies:Scorpio maurus (Linne, 1758)S. m. maurus (Linne, 1758) - Algeria, Morocco, TunisiaS. m. arabicus (Pocock, 1900) - Penisule ArabiaS. m. behringsi (Shenkel, 1949) - MoroccoS. birulai (Fet, 1997) - MoroccoS. fuliginosus (Pallary, 1928) - MoroccoS. m. fuscus (Ehrenberg, 1829) - Morocco?, Saudi-Arabia, Iraq, Israel, Jordan, Lebanon, Syria, Turkey, Yemen?S. hesperus (Birula, 1910) - MoroccoS. m. kruglovi (Birula, 1910) - Saudi-Arabia, Iran, Iraq, Jordan, Kuwait, Qatar, SyriaS. m. legionis (Werner, 1936) - Mauritanian SenegalS. mogadorensis (Birula, 1910) - MoroccoS. occidentalis (Werner, 1936) - Mauritanian SenegalS. m. palmatus (Ehrenberg, 1828) - Algeria, Egypt, Libya, Sudan, Israel, JordanS. m. propinquus (Simon, 1872) - SyriaS. punicus (Fet) - Algeria, Libya, Morocco, TunisiaS. savanicola (Lourenco, 2009) - CameroonS. m. stemmli (Shenkel, 1949) - MoroccoS. sudanensis (Lourenco, 2009) - SudanS. m. townsendi (Pocock, 1900) - IranS. m. trarasensis (Bousisset & Larrouy, 1962) - AlgeriaS. weidholzi (Werner, 1929) - MoroccoS. m. yemmensis (Werner, 1929) - Yemen The new system involves Scorpio birulai, S. hesperus, S. occidentalis, S. punicus, and S. weidholzi to be raised to species level and S. sudanensis and S. savanicola to be newly introduced. Understanding Scorpio maurusSince I'm pretty well known for being a big fan of the Scorpionidae family, questions about Scorpio maurus palmatus are asked now and then.Most of the questions are about housing these scorpions. However a few questions do stand out, these will be described below.Question:I know the main difference between a Scorpio maurus palmatus and a Pandinus imperator (clearly visible). But taking into account the Scorpio maurus palmatus looks very similar to Pandinus imperator as comes to the big chelae and overall build. Is there something which really is different between Pandinus imperator and Scorpio maurus palmatus?Answer:When you look at the ID-key of the Scorpionidae family you will find one very distinct difference in Pandinus and Scorpio.Scorpio doesn't have a stridulation organ, where Pandinus has a stridulation organ on pedipalp coxa and first pair of legs.Question:I have read Scorpio maurus palmatus doesn't have a stridulation organ, however I did hear them making a sound. Is this possible?Answer:Yes this is possible, Scorpio maurus palmatus makes a sound by striking the ground with the distal half of the metasoma.This is not anything like a stridulation organ, but does work as a response to possible predators.They make this sound as a warning. In captivity they might make this sound because they see the keeper as being a possible predator.Question:Is it true Scorpio maurus palmatus only lives for a very short time (usually less then 1 year)?Answer:The main problem with this species is the fact almost all of them are wildcaught specimens. The age is unknown and most adult specimens might be pretty old.The second problem is housing, most people tend to keep them as a desert species and thus giving them a low humidity and high temperature. As can be read in the "housing" section, this species require a specific type of housing.In nature it takes 2 to 3 years before Scorpio maurus palmatus reaches sexual maturity, when mature they should easily live for at least 3 years or more.Thanks to:- Lucian K.
