A Victorian Illustration Meets its 21st Century Counterpart
By Chuck Peters, Maine, USA
Having recently purchased a copy of Arabella Buckley’s delightful Life’s Children: Glimpses of Animal Life From the Amoeba to the Insects in a used bookstore, an illustration on page 49 caught my eye. It depicts a hydra delicately dangling from the roots of duckweed. As a high school biology teacher, my classroom is reasonably well stocked with aquaria and terraria that provide my students and me a variety of living material to observe. In one small tank we have large populations of both duckweed and brown hydra, but it had never occurred to me to look among the dangling roots for this type of behavior. Eager to check on Monday morning after having just read the book, my first observation was met with success! Just as Ms. Buckley described in 1880, I could readily see at least two hydra thus poised, and managed to capture a photo that is eerily similar to her drawing.
Photographic notes: The duckweed with attached hydra was transferred from the original tank to a glass “microaquarium” made of microscope slides to facilitate photography. Nikon D80 with 100mm macro lens, f16 at 1/60 sec, with bracket mounted flash, hand-held.
