Brazilian Black and White Spider Brazilopelma Colloratovilloseum The Brazilian Black and White Tarantula is a very rare, expensive, and desirable tarantula species! It is another beautiful black and white striped tarantula, like the Brazilian Whiteknee Tarantula (Acanthoscurria geniculata), but with broader strips of white hairs. This tarantula species can get fairly large too, adding to its appeal. The Brazilian Black and White Tarantula is not usually seen for sale in the United States, but can be found easier in Europe. These tarantulas aren't too aggressive, but won't hesitate to flick urticating hairs if disturbed. Brazilian Black and White Tarantulas can be great display tarantulas because they are so hard to obtain, along with the beauty they possess. Range Savannah, grassland, and pampas areas of Brazil. Type Terrestrial. Diet Spiderlings eat pinhead crickets and other small insects. Adults eat crickets, other large insects, small lizards, pinkie mice, and an occasional fuzzy mouse. Full Grown Size 6.5 to 8 inches. Growth Medium speed. Temperature 80 to 85° F. Humidity 75 to 80%. All tarantulas that have at least a 3" legspan may drink from a shallow, wide water dish. Temperament Semi-docile and calm. Housing Babies can live in a clear plastic deli-container with air holes. Adults can live in a 10 to 15-gallon tank. Floor space is more important than height. Substrate 3 to 4 inches of peat moss, or potting soil. Decor Logs, driftwood, cork bark, etc. make good hiding places. Moss can be added for floor cover. Other Names Brazilian Giant Black and White Tarantula. *Please note that ALL tarantulas have a certain amount of venom. Although most people are not affected by this species, some people may be allergic to the venom, or just more sensitive, making it a dangerous situation. This is one of the reasons that people should not handle this tarantula. Also, New World species of tarantulas like this one can flick urticating hairs off of their abdomens, which can also cause a reaction, depending on the person. Affects of this tarantulas' natural defenses may vary between people. All tarantulas should be considered dangerous, so be careful, because you don't want to find out if you are allergic or more sensitive the HARD WAY! .

Investigation of Hox Gene Expression in the Brazilian Whiteknee Tarantula Acanthoscurria Geniculata
Investigation of Hox gene expression in the Brazilian Whiteknee tarantula Acanthoscurria geniculata Dan Strömbäck Degree project in biology, Bachelor of science, 2020 Examensarbete i biologi 15 hp till kandidatexamen, 2020 Biology Education Centre and Institutionen för biologisk grundutbildning vid Uppsala universitet, Uppsala University Supervisor: Ralf Janssen Abstract Acanthoscurria geniculata, the Brazilian whiteknee tarantula, is part of the group Mygalomorphae (mygalomorph spiders). Mygalomorphae and Araneomorphae (true spiders) and Mesothelae (segmented spiders) make up Araneae (all spiders). All spiders have a prosoma with a pair of chelicerae, pedipalps and four pairs of legs, and an opisthosoma with two pairs of book lungs or one pair of book lungs and one pair of trachea (in opisthosomal segments O2 and O3) and one or two pairs of spinnerets (in segments O4 and O5). The mygalomorphs have retained two pairs of book lungs, an ancestral trait evident from looking at Mesothelae, the ancestral sister group of both Araneomorphae and Mygalomorphae. The spinnerets differ greatly between the groups, but this study focuses on comparing Mygalomorphae and Araneomorphae. Mygalomorphae also have reduced anterior spinnerets, but instead enormous posterior spinnerets. Araneomorphae possess all four, but none particularly big. The genetic basis of these differences between the set of opisthosomal appendages in tarantulas and true spiders is unclear. One group of genes that could be involved in the development of these differences could be the famous Hox genes. Hox genes have homeotic functions. If they are expressed differently between these two groups, the resulting morphology could change. This study focuses on the posterior Hox genes in A. geniculata, i.e.

G. Paiva∗ Departamento de Bioquímica, Centro de Ciências Biológicas, Universidade Federal de Pernambuco, Cidade Universitária, Recife, Pernambuco, Brazil ABSTRACT Arachnids compose the most important and numerous group of chelicerates and include spiders, scorpions, mites and ticks. Some arachnids have a worldwide distribution and can live for more than two decades. This is in part due to their efficient defense system, with an innate immunity that acts as a first line of protection against bacterial, fungal and viral pathogens. The adaptive success of the spiders stimulates the study of their defense mechanisms at cellular and molecular levels with both biological and biotechnological purposes. The hemocytes (plasmatocytes, cyanocytes, granulocytes, prohemocytes, and leberidocytes) of spiders are responsible for phagocytosis, nodulation, and encapsulation of pathogens as well as produce substances that mediate humoral mechanisms such as antimicrobial peptides and factors involved in the coagulation of hemolymph and melanization of microorganisms.

Italia 3318, Montevideo, Uruguay. E-mail: [email protected] Fernando PeÂrez-Miles: SeccioÂn EntomologõÂa, Facultad de Ciencias, IguaÂ 4225, 11400 Montevideo, Uruguay ABSTRACT. We describe the reproductive biology of seven theraphosid species from Uruguay. Species under study include the Ischnocolinae Oligoxystre argentinense and the Theraphosinae Acanthoscurria suina, Eupalaestrus weijenberghi, Grammostola iheringi, G. mollicoma, Homoeomma uruguayense and Plesiopelma longisternale. Sexual activity periods were estimated from the occurrence of walking adult males. Sperm induction was described from laboratory studies. Courtship and mating were also described from both ®eld and laboratory observations. Oviposition and egg sac care were studied in the ®eld and laboratory. Two complete cycles including female molting and copulation, egg sac construction and emer- gence of juveniles were reported for the ®rst time in E. weijenberghi and O. argentinense. The life span of adults was studied and the whole life span was estimated up to 30 years in female G. mollicoma, which seems to be a record for spiders. A comprehensive review of literature on theraphosid reproductive biology was undertaken. In the discussion, we consider the lengthy and costly sperm induction, the widespread display by body vibrations of courting males, multiple mating strategies of both sexes and the absence of sexual cannibalism.

Brazilian Giant White-Knee Tarantula Concise & Precise Care Sheet Glaking
BRAZILIAN GIANT WHITE-KNEE TARANTULA CONCISE & PRECISE CARE SHEET GLAKING OVERVIEW The Brazilian Giant White-knee Tarantula (Acanthoscurria geniculata) is a beautiful, robust and large tarantula that is very popular with keepers despite its skittish nature and defensive attitude. It is quick to flick its urticating hairs and somewhat prone to defend with a bite if provoked, but makes an impressive display spider due to its size, gorgeous pattern and color. This species has dark legs boldly striped with white, a greyish carapace and an abdomen covered with orangish-red hairs. Adult females commonly reach 7” in diagonal legspan. This spider is native to the forests of northern Brazil. It is extremely similar in appearance to another Brazilian species, Acanthoscurria brocklehursti and they are often confused by hobbyists. The latter is somewhat heavier bodied and has narrower bands of white at the leg joints. ENVIRONMENT Conditions » Day Temp 75-78°F Night Temp 70-75°F Humidity 65-80% Usually unnecessary. House enclosure in a warm area that provides appropriate temperature range and minimal drafts, light and vibration. If necessary, terrariums may be heated using a mini heat mat Heat Source » mounted beneath or a very low wattage red (or “nocturnal”) bulb safely suspended above. Small containers housing “spiderlings” are best heated by keeping inside a larger heated enclosure that acts as an incubator. A terrestrial cage with plenty of ventilation (a plastic critter keeper style terrarium is excellent), slightly moist substrate (commercial organic soil mixes are excellent, but coconut coir or 50/50 sphagnum peat moss/vermiculite mix are just as good), hiding place and small water dish — extra care should be used when raising HOUSING spiderlings as small containers typically used, such as vials or small jars with lids with small air holes, are too poorly ventilated (we use 16 oz.

Marine Biological Laboratory, Woods Hole, MA. *Correspondence to: [email protected] 10 Abstract How to align leg segments between the four groups of arthropods (insects, crustaceans, myriapods, and chelicerates) has tantalized researchers for over a century. By comparing the loss-of-function phenotypes of leg patterning genes in diverged arthropod taxa, including a crustacean, insects, and arachnids, arthropod legs can be aligned in a one-to-one fashion. By 15 comparing the expression of pannier and aurucan, the proximal leg segments can be aligned. A model is proposed wherein insects and myriapods incorporated the proximal leg region into the body wall, which moved an ancestral exite (for example, a gill) on the proximal leg into the body wall, where it invaginated independently in each lineage to form tracheae. For chelicerates with seven leg segments, it appears that one proximal leg segment was incorporated into the body 20 wall. According to this model, the chelicerate exopod and the crustacean exopod emerge from different leg segments, and are therefore proposed to have arisen independently. A framework for how to align arthropod appendages now opens up a powerful system for studying the origins of novel structures, the plasticity of developmental fields across vast phylogenetic distances, and the convergent evolution of shared ancestral developmental fields.

Morphology, Evolution and Usage of Urticating Setae by Tarantulas (Araneae: Theraphosidae)
ZOOLOGIA 30 (4): 403–418, August, 2013 http://dx.doi.org/10.1590/S1984-46702013000400006 Morphology, evolution and usage of urticating setae by tarantulas (Araneae: Theraphosidae) Rogério Bertani1,3 & José Paulo Leite Guadanucci2 1 Laboratório Especial de Ecologia e Evolução, Instituto Butantan.

Rodovia MGT 367, km 583, 39100-000 Diamantina, MG, Brazil. E-mail: [email protected] 3 Corresponding author. ABSTRACT. Urticating setae are exclusive to New World tarantulas and are found in approximately 90% of the New World species. Six morphological types have been proposed and, in several species, two morphological types can be found in the same individual. In the past few years, there has been growing concern to learn more about urticating setae, but many questions still remain unanswered. After studying individuals from several theraphosid species, we endeavored to find more about the segregation of the different types of setae into different abdominal regions, and the possible existence of patterns; the morphological variability of urticating setae types and their limits; whether there is variability in the length of urticating setae across the abdominal area; and whether spiders use different types of urticat- ing setae differently. We found that the two types of urticating setae, which can be found together in most theraphosine species, are segregated into distinct areas on the spider’s abdomen: type III occurs on the median and posterior areas with either type I or IV surrounding the patch of type III setae.
