I have therefore been able to do some research on this species and observe it extensively. The color mutation is more or less known as Porcellio scaber &#8220;White Out&#8221;.  <\/p>\n\n<p>In the first article, I discussed how Thomas Hunt Morgan experimented with fruit flies and white eyes. He discovered a gene that was linked to the color of the eyes and the sex of the fruit flies. Because of this discovery, I was concerned that this mutation would only occur in the male sex.  <\/p>\n\n<p>If you haven&#8217;t read the article yet, you can do so here:<\/p>\n\n<figure class=\"wp-block-embed is-type-wp-embed is-provider-insektenliebe wp-block-embed-insektenliebe\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"wp-embedded-content\" data-secret=\"cAJZp68Cd7\"><a href=\"https:\/\/insektenliebe.com\/en\/magazine\/breeding-magazine\/the-secret-of-woodlice-without-eyes\/\">Das Geheimnis der Asseln ohne Augen<\/a><\/blockquote><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"&#8220;Das Geheimnis der Asseln ohne Augen&#8221; &#8212; Insektenliebe\" src=\"https:\/\/insektenliebe.com\/en\/magazine\/breeding-magazine\/the-secret-of-woodlice-without-eyes\/embed\/#?secret=DuOFL5E8o7#?secret=cAJZp68Cd7\" data-secret=\"cAJZp68Cd7\" width=\"500\" height=\"282\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe>\n<\/div><\/figure>\n\n<p>So I wanted to take the next opportunity to examine the sexes in this mutation and see if both sexes were present.

Only 2 gray animals emerged. The mutation was therefore quite color stable and we only had to select very rarely.  <\/p>\n\n<p>The behavior of Porcellio scaber &#8220;White Out&#8221; does not differ from that of other isopod species. They like to eat the skin completely after moulting and use it as a source of calcium. <\/p>\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/insektenliebe.com\/wp-content\/uploads\/2020\/03\/IMG_2160.jpg\" alt=\"Porcellio scaber &quot;White Out&quot;\"\/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/insektenliebe.com\/wp-content\/uploads\/2020\/03\/IMG_2147.jpg\" alt=\"Porcellio scaber &quot;White Out&quot;\"\/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/insektenliebe.com\/wp-content\/uploads\/2020\/03\/IMG_2141.jpg\" alt=\"Porcellio scaber &quot;White Out&quot;\"\/><\/figure>\n<\/div>\n<\/div>\n\n<p>Now we come to the question of what color the Isopods&#8217; blood is and whether a pigment is actually necessary for the white eyes or whether they are simply transparent. Vertebrates have red blood. The red color comes from the red blood cells that transport oxygen. That&#8217;s why we humans sometimes have red eyes in photos. This occurs when the flash hits our eye at a certain angle. This makes our blood vessels visible in the eye and they appear red.     <\/p>\n\n<p>Arthropods and molluscs, which include our Isopods, have developed an alternative to our blood. It is called hemocyanin (from the Greek <i>h\u00e4m<\/i>, &#8216;blood&#8217; and <i>kyanos<\/i>, &#8216;sky-blue&#8217;). The name tells us quite a lot. Hemocyanin is colorless. However, if oxygen is transported, it has a sky-blue color.    <\/p>\n\n<p>This confirms that our Porcellio scaber &#8220;White Out&#8221; has white pigmented eyes.<\/p>\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/insektenliebe.com\/wp-content\/uploads\/2020\/02\/Porcellio-scaber-_White-Out_.jpg\" alt=\"Porcellio scaber &quot;White Out&quot;\"\/><\/figure>\n\n<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<p>During my research I came across a new Porcellio scaber mutation. It is called Porcellio scaber &#8220;Lucy&#8221;. The appearance is white, like our Porcellio scaber &#8220;White Out&#8221;, but this mutation has black eyes. Now the question arises whether the white eye color can be transferred to other Porcellio scaber color variants, or whether it is genetically possible to transfer the black eye color to the Porcellio scaber &#8220;White Out&#8221;. I will therefore continue the project and cross different color variants with each other.    <\/p>\n\n\n\n<p>You&#8217;ll find out how I&#8217;m going to do this in the next article.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"wp-block-embed is-type-wp-embed is-provider-insektenliebe wp-block-embed-insektenliebe\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"wp-embedded-content\" data-secret=\"CKRgI6AP4t\"><a href=\"https:\/\/insektenliebe.com\/en\/magazine\/breeding-magazine\/from-the-gray-mouse-to-the-designer-morph\/\">Von der grauen Maus zur Designer Morphe<\/a><\/blockquote><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"&#8220;Von der grauen Maus zur Designer Morphe&#8221; &#8212; Insektenliebe\" src=\"https:\/\/insektenliebe.com\/en\/magazine\/breeding-magazine\/from-the-gray-mouse-to-the-designer-morph\/embed\/#?secret=gsVujAJcqa#?secret=CKRgI6AP4t\" data-secret=\"CKRgI6AP4t\" width=\"500\" height=\"282\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe>\n<\/div><\/figure>\n<\/div>\n<\/div>\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<div data-block-name=\"woocommerce\/single-product\" data-product-id=\"150865\" data-wp-context=\"{&quot;productId&quot;:150865,&quot;variationId&quot;:null}\" data-wp-interactive=\"woocommerce\/single-product\" class=\"wp-block-woocommerce-single-product woocommerce\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:512px\"><div data-block-name=\"woocommerce\/product-image\" data-is-descendent-of-single-product-block=\"true\" data-show-sale-badge=\"false\" class=\"wc-block-components-product-image wc-block-grid__product-image wc-block-components-product-image--aspect-ratio-auto wp-block-woocommerce-product-image\"><a href=\"https:\/\/insektenliebe.com\/en\/shop\/product\/porcellio-scaber-white-out\/\" style=\"\" data-wp-on--click=\"woocommerce\/product-collection::actions.viewProduct\"><img decoding=\"async\" width=\"600\" height=\"600\" src=\"https:\/\/insektenliebe.com\/wp-content\/uploads\/2019\/04\/Porcellio-scaber-22White-Out22-Laub-600x600.jpg\" class=\"attachment-woocommerce_single size-woocommerce_single\" alt=\"Porcellio scaber &quot;White Out&quot;-Laub\" data-testid=\"product-image\" data-image-id=\"199734\" style=\"object-fit:cover;\" loading=\"lazy\" srcset=\"https:\/\/insektenliebe.com\/wp-content\/uploads\/2019\/04\/Porcellio-scaber-22White-Out22-Laub-600x600.jpg 600w, https:\/\/insektenliebe.com\/wp-content\/uploads\/2019\/04\/Porcellio-scaber-22White-Out22-Laub-300x300.jpg 300w, https:\/\/insektenliebe.com\/wp-content\/uploads\/2019\/04\/Porcellio-scaber-22White-Out22-Laub-150x150.jpg 150w, https:\/\/insektenliebe.com\/wp-content\/uploads\/2019\/04\/Porcellio-scaber-22White-Out22-Laub-768x768.jpg 768w, https:\/\/insektenliebe.com\/wp-content\/uploads\/2019\/04\/Porcellio-scaber-22White-Out22-Laub-100x100.jpg 100w, https:\/\/insektenliebe.com\/wp-content\/uploads\/2019\/04\/Porcellio-scaber-22White-Out22-Laub.jpg 820w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><div class=\"wc-block-components-product-image__inner-container\"><\/div><\/a><\/div><\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"padding-top:var(--wp--preset--spacing--30);padding-bottom:var(--wp--preset--spacing--30)\"><h2 class=\"wp-block-post-title has-x-large-font-size\"><a href=\"https:\/\/insektenliebe.com\/en\/shop\/product\/porcellio-scaber-white-out\/\" target=\"_self\" >Porcellio scaber &#8220;White Out&#8221;<\/a><\/h2>\n\n<div data-block-name=\"woocommerce\/product-price\" data-font-size=\"large\" data-is-descendent-of-single-product-block=\"true\" data-style=\"{&quot;typography&quot;:{&quot;fontStyle&quot;:&quot;normal&quot;,&quot;fontWeight&quot;:&quot;700&quot;}}\" style=\"font-style: normal; font-weight: 700; font-style:normal;font-weight:700;\" class=\"has-font-size has-large-font-size wp-block-woocommerce-product-price has-large-font-size\" ><div class=\"wc-block-components-product-price wc-block-grid__product-price\" >\n\t\t\t\t\t<span class=\"woocommerce-Price-amount amount\"><bdi>55,00&nbsp;<span class=\"woocommerce-Price-currencySymbol\">&euro;<\/span><\/bdi><\/span> <small class=\"woocommerce-price-suffix\">incl.
