It has been my experience that most of the iguanas that have egg-related problems once will have them again. Reproduction in the iguana is complicated, involving the interplay between temperature, light cycles, humidity, season, availability of adequate nesting sites and more. Mating and egg-laying take place between January and March, the hottest months. Reproduction in the marine iguana begins during the cold and dry season. A spay renders the animal incapable of breeding. As mentioned, calcium is extremely important in maintaining normal physiology. If you do not see membranes, it may still be a post-ovulatory condition, it is just in the stage prior to the deposition of the shell. Although this looks strange at first, it offers the best healing potential. There are around 4,500 marine iguanas per square mile in the galapagos islands. Many iguanas sold through pet stores advertised as "captive born" are the progeny of gravid females that were caught in the wild, then allowed to oviposit in captivity. The Galapagos hawk is a natural predator of the marine iguana. However, in captive pet iguanas, unless we are trying to breed them, we really don't want them to ovulate. It is a common misconception that all iguanas brought to veterinarians gravid are in life-threatening danger of being unable to pass eggs. Located on Turneffe Atoll, 25 miles off the coast of Belize…, A rail car and 70-foot steel tugboat were recently purpose-sunk Hempstead Reef in an expansion of New York State's artificial reef program. This is quite serious, as mammary cancer is a common disease in the older female dog, and can potentially kill the pet if not caught and treated in time. The problem is that a female will normally become anorectic, or lose her appetite, for about four weeks prior to egg laying. They still must be managed medically, but once stabilized it may be possible to induce oviposition and avoid the need for surgery. Some females also turn red.

It sure is a lot easier and safer than doing surgery later on an animal that is depressed, hypocalcemic and near death. And amazing prices in Costa Mujeres! The cycle will repeat again the following breeding season. Mature male iguanas have a very typical appearance: broad heads; large, ornate opercular scales; extensive, fanlike gular flap; impressive dorsal spines; and often, especially in breeding season, brilliant colors. Marine Iguanas are the only ocean lizards in the World. Whether that represents two distinct seasons or just a late laying (fall) is a matter of debate. In fact, with reptiles, doesn't it seem that we usually encourage captive-breeding of the animals to cut down on the importation and exportation of wild-caught animals and decrease the numbers of sick and stressed lizards? If you suspect that your pet may be gravid, have it examined by an experienced herpetoculturist or your favorite herp veterinarian.

Galapagos Marine Iguana Reproduction Territory is very important concern for the Galapagos Marine Iguana. Noyes, Park Ridge, NJ. If left in that condition, the follicular membranes will coalesce, forming one large mass of friable yolk. It is sometimes possible to distinguish between pre- and post-ovulatory egg retention by taking an X-ray. Once stabilized, which may take a few hours to a few days, the animal can be induced to lay, assuming all other medical factors are in check or, if not, taken to surgery for removal of the eggs. If an appropriate beach area is not available, they have been seen swimming miles upstream or downstream to find such a place. They must be medically managed, stabilized and then, if the owners are willing, taken to surgery to have the source of the problem, the reproductive tract, removed. Reproduction and Offspring The iguanas live in colonies of 20 to 1,000 lizards. A major change in the marine algal flora occurred between November 1982 and July 1983. It is not uncommon, as well, for these animals to show signs of hypocalcemic tetany, as their body tries to maintain the eggs at the expense of their calcium homeostasis.

Even some zoos, with their highly skilled herpetologists, have a hard time getting these animals to consistently reproduce in captivity. If they do breed, and the eggs are fertile, oviposition (egg laying) and incubation represent yet another obstacle. It is best to take all the factors into consideration when assessing gender. The species age can reach up to 60 years while the average age of these species is about only 12 years. In pre-ovulatory egg retention, the animal develops mature follicles, but due to some physiological intervention, there is follicular stasis prior to actual ovulation. Once the sutures have been removed (they must be left in at least four weeks), the skin flattens out, looking like normal belly skin. If at the time of the eight-week recheck the eggs are now post-ovulatory, or if the patient is doing poorly (lethargic, weight loss, tremors), I recommend hospitalization and attempting to induce oviposition with calcium and oxytocin.
