Macroinvertebrates in the San Marcos River
When one thinks of critters in the San Marcos River, fish, turtles and, on the occasional terrifying day, water moccasins come to mind. There are also tons of small (but large enough to be seen by the unaided eye), backboneless critters called macroinvertebrates, and Kellie Donajkowski, Edwards Aquifer Research and Data Center education program manager, told a group of curious locals all about the ones in the San Marcos River. This was the fifth course in a lecture series spearheaded by Lifelong Learning Director Marianne Reese that occurred on six consecutive Fridays at the San Marcos Public Library.
Donajkowski said that the macroinvertebrate category encompasses a wide array of creatures, including crawfish, leeches, spiders, mussels, worms, slugs and snails.
