11/20/2023 0 Comments Lantern fish reproduction![]() Biological samples from the deep sea are hard to come by, but with the help of ichthyologist Theodore Pietsch, an expert on deep-sea anglerfishes at the University of Washington, the team was able to obtain tissue samples from several specimen collections.īoehm and his colleagues sequenced the DNA from 31 specimens, representing 13 species of deep-sea anglerfish. Immunologist Thomas Boehm and his colleagues at the Max Planck Institute of Immunology and Epigenetics in Germany long wanted to know how some anglerfish species can form bodily fusions between individuals, and set out to do an analysis of the animals’ genomes. Evolution produces all sorts of wacky outcomes, and this is one of them.” “I suppose we shouldn’t have too many preconceptions about what is and isn’t possible in nature. “It’s quite shocking,” remarks geneticist Elizabeth Murchison of the University of Cambridge who wasn’t involved in the study. ![]() Over the course of evolution, changes in genes involved in antibody production and cytotoxic T cell responses may have paved the way for the animals’ strange reproductive habits, while for scientists it raises questions about how the fish defend themselves against pathogens in the deep sea. The genomes of species that temporarily or permanently fuse with their mates have undergone radical alterations of key genes that underpin adaptive immunity-a branch of the immune system responsible for the rejection of foreign tissue-making some of them the first known instances of vertebrates that effectively lack an adaptive immune system. Specimens are ethically sourced, helping to fund efforts in butterfly repopulation and land conservation.A new genomic analysis of 13 anglerfish species published today (July 30) in Science provides some clues. ![]() See our listing for custom work for more details.įrames are available empty in standard and custom sizes and finishes. Your photographs, artwork, or silhouettes can be used for customized butterfly wing art. Expect the average dimensions for each size:Ĩx10 Frame: inner opening approx 7.5x9.5” ![]() SIZES are approximate, as each frame is handmade from real pine tree wood, which has individual variations, and comes out slightly unique. These are heavy, sturdy frames, with thick glass. Variations in wood grain and resulting finish are to be expected. Every frame is handmade, and one of a kind. Solid wood (pine, unless otherwise noted) with your choice of finish. Shadow box frames are handmade in central Minnesota. Please use the box for notes during checkout. Requests will be honored as closely as possible. Specific wing colors, species and shape requests are welcome. *Wings chosen based on artist interpretation and availability. SPECIAL WINGS include most metallic colored wings, intricate pattern wings, and other more coveted and/or rare species.Though they tend to be more golds, neutral shades and earth-tones, there are vibrant colors included in the mix. Species information and story card included. Each piece is artist signed, one of a kind, and even prettier in person. Printed using acid-free archive-quality materials on waterproof paper.
