Aquarists thought that Leif, a Meller’s chameleon on view in Waters of the World, was just gaining weight. Then a series of X-rays revealed that she was full of developing eggs – so full, in fact, that “she looked like a gumball machine,” says senior aquarist Stacy Wozniak. About a month ago, the 2-foot-long lizard spent a morning laying 60 oval eggs in the moss at the back of her habitat.

The scientists, staff and volunteers of Shedd's annual West Indian Rock Iguana Research Expedition have returned home after a successful trip to the Bahamas.
Working with Dr. Chuck Knapp gave us a new appreciation for the difficult and rewarding nature of field work. Our team of volunteers and scientists have returned to our day jobs, but the work of Dr. Knapp and Dr. Trevor Zachariah (pictured) continues. One of Dr. Knapp's goals is to use the data the volunteer groups gathered to help the Bahamian government protect a large part of South Andros Island. The 47 iguanas collected, carefully measured and tagged will bring Dr. Knapp closer to his goal of securing a protected area for the Andros Iguanas.

Few animals at Shedd have the drawing power of the big alligator snapping turtle sitting doing nothing. With his back to the crowd. What is it that fascinates people? Try size, longevity and perceived danger. Here are the facts:
Oh, yes, these turtles get big – in fact, Macroclemys temmincki, as scientists know it, is the largest freshwater turtle species in North America. Alligator snappers can grow to 175 pounds in the wild, and even heavier – the record is 251 pounds – in aquariums and zoos, where the meals are more regular.

All of the day-to-day operations on the R/V Coral Reef II are all handled by just three people. Our two captains, Captain John Rothchild and Captain Lou Roth, don't just navigate the boat. They also fix whatever breaks and keep everything in ship shape. They are helped by Chef Matt Cohen, who cooks our breakfast lunch and dinner. In this podcast, Captain Lou Roth talks about life on the R/V Coral Reef II and why he always enjoys the annual iguana research trip.

We have been working hard to collect and study as many iguanas as we can over the past few days, and each day we look forward to returning to the R/V Coral Reef II (pictured) so that we can hook up our satellite terminal and download all of your questions and comments. It feels great to know students across the United States are learning along with us, and we really enjoy answering your questions. At night we are busy processing all of the blood samples that are collected from the iguanas we collected, but we are doing our best to answer as many questions as we can each night. We have answered some of your questions below, and we look forward to answering more soon.
"What is the longest iguana you've ever found?"
Head to tail iguanas can be as long as 52 inches (132 centimeters)
"How do iguanas talk to each other?"
Iguanas don't exactly talk to each other like people do, but they do communicate with one another through bobbing their heads, puffing up their bodies and other movements.

Here are answers to some of the questions members of the Rock Iguana Research Expedition have received over the past few days:
"What types of fish live in the water? Can you take pictures of them under the water?"
There are hundreds of fish in the Bahamas, but some of the more common fish we might see while snorkeling in Andros include: spotted eagle rays, barracuda, parrotfish, needlefish, snappers, nassau grouper, sergeant majors, bluehead wrasse and nurse sharks. Hopefully you can research some of these fish on your own. Yes, it is possible to take pictures underwater with special waterproof cameras.

Iguana research proves to be hard, but rewarding.
From our floating research station, the R/V Coral Reef II, we are studying the Bahamian Andros iguana. Finding iguanas can be difficult, and today was our first day scrambling over rocky, brush-choked terrain searching for these large, endangered lizards.
Adrenaline surges through you when an iguana is spotted and it takes teamwork to surround and collect each animal. We spotted ten animals and were able to collect and release four of them. Dr. Knapp is gathering a wealth of data which he hopes will lead to a National Park set up specifically to protect the Andros iguanas.
Shedd has been active in Rock Iguana conservation, studying several Rock Iguana populations in the Bahamas since 1994. Volunteers have been helping researchers through Shedd's annual Iguana Research Expedition for the past 13 years.
Through its partnership with Wilderness Classroom, students, teachers, parents and friends will be able to learn right along with researchers and volunteers via blogs, photos, videos, and more. This unique opportunity will allow you to share the experience with us from your own home or classroom.

Two green tree pythons, sisters Jasmine (pictured) and Ivy, have joined the Animal Encounters program. You’ll see one or the other 4-foot snake comfortably looped on a branch, held by a staff member, as if she were on a tree – because this species is almost completely arboreal. The deep pits visible in the upper and lower lips detect infrared radiation—heat from warm-blooded prey. Hidden in the rain forest canopy, its prehensile tail grasping a branch, a green tree python strikes from an S-shaped position to grab a rodent on the ground or a baby bird in a tree, constrict and swallow it whole. Being nocturnal and a little shy—and well-fed—Jasmine and Ivy are well-behaved around guests. See them soon!
