Robert Higgins: The Father of Mud Dragons and Loricifera
Robert Higgins, a marine biologist, has dedicated his life to studying meiofauna, tiny creatures that live in the spaces between sand grains. Among his many discoveries, Higgins has found new species of kinorhynchs, mud dragons, and even a new phylum of animals called Loricifera.
Higgins’ Early Career and the Discovery of Kinorhynchs
Higgins’ journey into the world of meiofauna began in the 1950s at the University of Colorado. While studying invertebrates, he encountered tardigrades, microscopic animals known for their resilience. Fascinated by their adaptability, Higgins decided to focus his master’s thesis on them.
One summer, Higgins traveled to the University of Washington’s marine laboratory, where he was tasked with collecting kinorhynchs. Despite never having seen one before, he developed a technique called “bubble and blot” to extract them from sediment samples. This method revolutionized the study of kinorhynchs and became a standard practice in meiofauna research.
The Discovery of Loricifera
In 1974, while collecting meiofauna off the North Carolina coast, Higgins discovered a strange creature unlike anything he had ever seen before. He preserved the specimen, but it wasn’t until years later, in collaboration with Reinhardt Kristensen from the University of Copenhagen, that he realized its significance.
In 1982, Kristensen collected more specimens of the same animal near France. Together, they discovered that these creatures represented a new phylum, which they named Loricifera, meaning “girdle wearer.” This discovery was a major breakthrough in zoology, as only four new phyla had been described in the 20th century.
Higgins’ Legacy in Meiofauna Research
Throughout his career, Higgins played a pivotal role in promoting the study of meiofauna. He co-founded the International Association of Meiobenthologists and launched its newsletter, fostering communication and collaboration among researchers. He also co-authored the “Introduction to the Study of Meiofauna,” a seminal work that has become a standard textbook in the field.
Higgins’ generosity and mentorship extended beyond his colleagues. He designed and shared research tools, such as the “mermaid bra” net, which is still used by meiofauna researchers today. He also encouraged younger scientists, including Fernando Pardos, who went on to become a leading kinorhynch taxonomist.
The Importance of Interstitial Spaces in Science
Higgins’ work highlights the importance of interstitial spaces in science. Just as meiofauna thrive in the gaps between sand grains, scientific discoveries often occur in the spaces between formal settings. Casual conversations, chance encounters, and unexpected observations can lead to groundbreaking insights.
