Over the past few weeks I found a couple of unusual animals in my education trawls. Both of my new friends were caught in the same net pull. One was something that, while rare, I’ve encountered a handful of times. The second critter is something that I’ve seen before, but never caught alive in any of the hundreds of trawls I’ve done.
The first animal is a common or brown spiny sea star. What makes this one uncommon, however, is the fact that it has six arms rather than five! Also, close examination of the photograph revealed that the sea star appears to have multiple madreporites, which is the organ that they use to control the amount of water in their bodies. They usually only have one. It seems the extra leg may have emerged after the body got damaged, but this is just a guess. One other thing that is exciting about this sea star is that it is the first one that I’ve encountered in the backwaters following hurricane Irma!
Nesting season is in full swing for the burrowing owls here in southwest Florida. I recently joined Alli Smith, a graduate student from the University of Florida, to assist with owl monitoring efforts taking place on Marco Island. Alli is the research manager for Audubon of the Western Everglades, and heads up the volunteer-run program OWL WATCH. Alli worked at Rookery Bay Research Reserve last year as an avian intern with Audubon.

Things outside are starting to change! Have you started to notice? It’s a slight change every day, but our days are getting longer and our nights are getting shorter. This does not just affect us humans either. The equinoxes are one of the many signals flora and fauna around the world use to time their annual cycles.
I have been monitoring shorebirds using the many different habitats within Rookery Bay Reserve this winter. For the most part, I have been counting similar breakdowns of diversity (number of different species) and abundance (number of individuals) over the whole season. These last few weeks though, I have begun to see some shifts in my survey data as well as in the birds themselves!
