Hydra budding, SEM
Hydra budding. Coloured scanning electron micrograph (SEM) of a Hydra sp. freshwater hydrozoan budding. Hydra commonly reproduce by budding - a form of asexual reproduction in which a new organism develops from an outgrowth or bud on another one (as seen here). They catch small swimming crustaceans such as daphnia using stinging and adhesive cells on their tentacles (top). Prey is ingested via a mouth (circular, upper centre) at the base of the tentacles. Magnification: x50, when printed 10 centimetres wide

EDITORS COMMENTS
This print captures the intricate process of Hydra budding, revealing the fascinating world of a freshwater hydrozoan. In this coloured scanning electron micrograph (SEM), we witness a moment of asexual reproduction as a new organism develops from an outgrowth or bud on another Hydra sp. specimen. Hydra, known for their ability to reproduce through budding, showcase their remarkable survival strategy in this image. With stinging and adhesive cells on their tentacles, they skillfully capture small swimming crustaceans like daphnia for sustenance. The top view showcases these tentacles in all their glory while highlighting the prey-catching mechanism. At the base of these magnificent tentacles lies a circular mouth where ingested prey enters the Hydra's digestive system. This central feature is prominently displayed in the upper center of the image, drawing our attention to its vital role in nourishing this unique creature. With a magnification factor of x50 when printed 10 centimeters wide, Steve Gschmeissner's masterful use of SEM technology allows us to explore every minute detail with awe-inspiring clarity. From vibrant colors to intricate textures, this photograph brings forth not only scientific knowledge but also artistic appreciation for nature's wonders. As we delve into this mesmerizing snapshot from Science Photo Library, let us marvel at how life perpetuates itself through cloning and budding among these extraordinary aquatic creatures called Hydra.
