If you live in the St. Louis area, consider enrolling in our Keeper for a Day program, for students in Grades 2 through 8. Working alongside a keeper in our Children's Zoo, you'll help care for some of our zoo animals, and go behind the scenes to learn what it takes to be a zookeeper. Work hard in school, not just in classes on science and nature but in all subjects. Chances are you still don't know for sure what you want to do when you grow up.
Fennec foxes mate for life. After a gestation period of about 50-53 days, a female will give birth to a litter of 2 - 5 young. Fennec foxes have extremely large ears that help them to keep cool in the hot desert. The ears also enable the fox to hear prey that may be hiding underground or far away.ennec foxes weigh approximately 3 - 3.5 pounds and are about 15 inches in length not including the tail. This makes it the smallest member of the Canidae family, who has members such as wolves and coyotes. The coat is a red to tan color to help it blend in with its surroundings.
Sperm can remain alive in these glands and fertilize eggs for up to 3 weeks. A hen will have maximum fertility for only about 3 to 4 days after one mating. For this reason, the male-to-female ratio in a flock must be enough to ensure mating of every hen every 3 days or so.Sperm do not break through the eggshell.Instead they travel up the oviduct to the infundibulum to join with the egg yolk. hen will have maximum fertility for only about 3 to 4 days after one mating.
