The Calusa Nature Center and Planetarium has announced that its Nature Speaker Series 2022 guest speaker for June is Sylvester “TJ” Muller, an open water diver and caver. It will take participants on an underground photographic and educational journey to discover the unseen connections to our Florida ecosystem through underwater caves. His presentation is at 7 p.m. Wednesday, June 8 at the Calusa Nature Center Planetarium.

“Very few people visit these caves, so we’re especially excited to see Mr. Muller’s photos and hear his stories about Florida’s hidden ecosystem.” said Carrie Nameth, CNCP’s environmental education coordinator.

Mr. Muller is an experienced open water and cave diver, having reached depths of 405 feet and explored some of Florida’s tightest caves. He will share photos of dives in several underwater caves and describe the unique features and life found there. He will explain the connection between the caves and the Florida surface ecosystem and the work he has done to protect these endangered treasures.

“TJ is an avid, passionate diver and a great storyteller,” said CNCP friend and administrator Britta Soderqvist. “His talk is not to be missed if you love Florida and its wild places.”

Mr. Muller served on the board of directors of the cave diving section of the National Speleological Society for eight years and is its past president. During his tenure, he undertook the only successful lawsuit against a municipality on behalf of the NSS, preserving Alachua Sink/Mill Creek for future generations. He organized and reworked the management plan for Eagles Nest Cave, twice saving it from permanent closure.

Tickets are available online at, $15 for non-members and free for CNCP members.
