        • A Sea Biscuit's Life

          This video shows the life cycle of the sea biscuit Clypeaster subdepressus and is part of my master's thesis project at the Biosciences Institute of University of São Paulo. We collected adults from sand beds of São Sebastião Channel (São Sebastião, SP, Brazil) and induced gamete release (eggs and sperm). We did the fertilization in vitro and followed the embryonic development in the laboratory, under light microscopy. Embryos become swimming larvae, approximately 0.2 mm wide, which we fed with microalgae until metamorphosis. A diminute sea biscuit grows inside the larva. When the minuscule podia and spines are formed the larva sinks and undergoes metamorphosis. The juvenile sea biscuit resorbs the larval tissue and begins to explore its new habitat, between sand grains. Scientific version of the video (aka article): http://www.plosone.org/article/info:doi/10.1371/journal.pone.0009654 We did the footage in the Marine Biology Center of University of São Paulo (CEBIMar-USP), located in São Sebastião, SP, Brazil, northern shore of State of São Paulo. http://www.usp.br/cbm You can find more information about this project in the website. http://mestrado.organelas.com Download the soundtrack from the netlabel AEROTONE. http://tinyurl.com/MyFirstTrumpet-Frerk This video is under a Creative Commons by-nc-sa license. http://creativecommons.org/licenses/by-nc-sa/2.5/br/ [taxonomy:binomial=Clypeaster subdepressus] [taxonomy:kingdom=Animalia] [taxonomy:phylum=Echinodermata] [taxonomy:class=Echinoidea] [taxonomy:order=Clypeasteroida] [taxonomy:family=Clypeasteridae] [taxonomy:common=Sea biscuit] [taxonomy:common=Sand dollar]

          • Dragonfly nymph sheds its skin

            02:05

            from Andy Holt Added 479 32 8

            The site of a dragonfly nymph emerging from the water and crawling up a stem, where it sheds its skin to reveal an adult dragonfly is well documented, however, this is just the final stage of a series of moults that have occurred throughout the dragonfly's life. Each moult allowing the nymph to grow beyond the confines of its rigid exoskeleton and facilitating a gradual metamorphosis towards the final adult stage. Although the earlier moults are less spectacular transformations than the final moult to the flying adult dragonfly, these intermediate moults still bring about subtle changes, including a steady development of the wing buds. Look out for the wing buds splitting and raising at the outset of the moult. By the time it emerges from the water a hawker nymph will have moulted 12-15 times.

Final fashion project by Leyre Valiente. A fantastic and metaphorical journey from fetus (when we all are pure and simple) to chimaera; the complicate yet beautiful monster we get to be when we grow up. C H I M AE R A (From lat. chimaera, and this from gr. cimaira, fantastic animal) 1 Greek Mythology a fire-breathing female monster with a lion's head, a goat's body, and a serpent's tail. 2 something hoped for but illusory or impossible to achieve. 3 Biology an organism containing a mixture of genetically different tissues, formed by processes such as fusion of early embryos, grafting, or mutation. (Concise Oxford English Dictionary © 2008 Oxford University Press) Chimerical animal, fantastic, bizarre. Taboo became flesh. Light sketch of our nature, hidden, terrible, magical. A mutant made of scars, indelible traumas, experiences, fears, desires... Built from parts of itself or from others, sewn without an anesthetic. Unic in its species. Beautiful on its complexity. The monster is different and superior. That is why it produces fear and the need of having it under control. Made equally of dream and nightmare. It seduces and attracts because it is strange and misterious, ethereally intangible. It is splendid, hypnotic, although being fearful. It is as part of this world as good and evil, but it is quite above it and can fly overhead with its dragon wings. It sinks imaginary ships with its tentacles and devours souls with its jaws. It is carnivorous, cruel like a kid burning ants. It hides in the shadows like a cursed creature because of its fear of being hunted, judged. Its soul is dark, because it has seen the light. The chimera laughs, mocking the human being, “And you dare to judge me?” COLLECTION DESCRIPTION: The human being suffers along all his life, a series of emotional and conductual modifications that lead to self-reeducation of the character, and sometimes, to traumas that change (mutate) the personality creating a new being. The fetus is clean and pure, and is educated to stay that way, educated to tame the creature beneath. But his experiences make him react and learn, making the monster show up in some occasions. This monster does not have to be something ugly or negative. He is just different, and because of that, he causes rejection. That rejection can make the creature grow apart from his environment and the way he is supposed to be, becoming something dark and gloomy. That's when he learns to build shields around himself to block the sadness out, and only when he feels comfortable in his new form, will he be strong enough to emerge proudly as this complex and beautiful new creature: the chimaera. The mutating skin: Skin-tone silk and knit fabrics. Textures like veins, tendons and bones showing up under the skin, translated to dresses by chords sewn beneath the fabric. Simmetry. Stitches imitating scars. The slithering body: Shiny black leather pleated and overlaped creates the shape of a dark slippery sea creature. Saint George and the dragon: A contrast between the strengh of the brass armor parts and the soft silk that imitates the wings of the dragon.
