Under a low magnification of only 52x, approximately twice that of PHIL 10075, this scanning electron micrograph (SEM) depicted the dorsal cephalothorax, i.e., a combination of its head and thoracic regions, of a venomous brown recluse spider, Loxosceles reclusa, found inhabiting a Kentucky farm. Most spiders possess eight eyes (4 pairs), however, recluse spiders only possess six. L. reclusa is sometimes referred to as the violin or fiddle spider, for on its cephalothorax one will see what appears to be coloration in the shape of these stringed instruments, which is quite evident in the color photograph PHIL 1125, depicting a live specimen. Youll also note this spiders four pairs of jointed legs, which places it in the Phylum, Arthropoda, and the Class, Arachnida. Also see PHIL 2224, and 6268 for additional brown recluse images.Created: 2007

Under a low magnification of only 27x, twice that of PHIL 10074, this scanning electron micrograph (SEM) depicted the dorsal cephalothorax, i.e., a combination of its head and thoracic regions, of a venomous brown recluse spider, Loxosceles reclusa found inhabiting a Kentucky farm. Most spiders possess eight eyes (4 pairs), however, as is evidenced in this image, recluse spiders only possess six. L. reclusa is sometimes referred to as the violin or fiddle spider, for on its cephalothorax one will see what appears to be coloration in the shape of these stringed instruments, which is quite evident in the color photograph PHIL 1125, depicting a live specimen.

Under a very low magnification of only 14x, this scanning electron micrograph (SEM) depicted the dorsal surface of a venomous brown recluse spider, Loxosceles reclusa, found inhabiting a Kentucky farm. Most spiders possess eight eyes (4 pairs), however, recluse spiders only possess 3 pairs. L. reclusa is sometimes referred to as the violin or fiddle spider, for on its cephalothorax, i.e., a combination of its head and thoracic regions, one will see what appears to be coloration in the shape of these stringed instruments, which is quite evident in the color photograph PHIL 1125, depicting a live specimen.

Under three increasingly greater magnifications, this being the highest at 3248X (see PHIL 10089, 10090), what is depicted here is an unidentified pore located on the dorsal abdomen of a venomous brown recluse spider, Loxosceles reclusa, found inhabiting a Kentucky farm. Note the material surrounding the pores orifice, and as the magnification increases, it becomes evident that the material is composed of an unidentified bacterial biofilm. It is not known if these were existing symbiotically upon the spiders exoskeleton, or if they were pathologic in nature, signifying manifestations of a progressive disease process? See PHIL 10088 for a black and white version of this image.L. reclusa is sometimes referred to as the violin or fiddle spider, for on its cephalothorax one will see what appears to be coloration in the shape of these stringed instruments, which is quite evident in the color photograph PHIL 1125, depicting a live specimen.Created: 2007

Under three increasingly greater magnifications, this being midway at 732X (see PHIL 10089, 10091), what is depicted here is an unidentified pore located on the dorsal abdomen of a venomous brown recluse spider, Loxosceles reclusa, found inhabiting a Kentucky farm. Note the material surrounding the pores orifice, and as the magnification increases, it becomes evident that the material is composed of an unidentified bacterial biofilm. It is not known if these were existing symbiotically upon the spiders exoskeleton, or if they were pathologic in nature, signifying manifestations of a progressive disease process?

Under three increasingly greater magnifications, this being the lowest at 183X (see PHIL 10089, 10090), what is depicted here is an unidentified pore located on the dorsal abdomen of a venomous brown recluse spider, Loxosceles reclusa, found inhabiting a Kentucky farm. Note the material surrounding the pores orifice, and as the magnification increases, it becomes evident that the material is composed of an unidentified bacterial biofilm. It is not known if these were existing symbiotically upon the spiders exoskeleton, or if they were pathologic in nature, signifying manifestations of a progressive disease process? See PHIL 10086 for a black and white version of this image.L. reclusa is sometimes referred to as the violin or fiddle spider, for on its cephalothorax one will see what appears to be coloration in the shape of these stringed instruments, which is quite evident in the color photograph PHIL 1125, depicting a live specimen.Created: 2007
