Meet our new baby crested gecko

We welcomed a new baby crested gecko into our Animal Ambassador colony on Sunday, August 12, 2018! Unlike human babies, juvenile hatchling crested geckos are capable of taking care of themselves as soon as they hatch. The hatchling was separated from its parents, Pogo and Terra, since it’s safer for the young one. Incubation time for crested gecko eggs can take anywhere from 60–140 days, depending on the temperature they are being incubated at. Right now it is only a couple of inches long, but will eventually reach to a size of 4–8 inches.

Though it won’t be ready to meet visitors quite yet, you can visit our other crested geckos and all our Animal Ambassadors daily in the Animal Discovery Room (ADR) from 1:30 to 4:00 p.m.

Make a Donation

Our new Turtle Tank

We house about 50 species of animals and attempt to maintain variation in the ADR when accepting animal donations. Please contact us if you are interested in donating your animal or used animal enclosure to find out if it meets all of our criteria. ADR animals must be easily handled and even-tempered.

Check out our beautiful 300-gallon tank purchased by donations from the Sally Molander Memorial Gift fund and from our generous Lawrence Hall of Science visitors. Observe the turtles exploring their new habitat, sunbathing in their larger land area, and showing off their swimming skills.

We Care About Our Animals

Special care is taken to ensure that all of our animals are housed correctly, with the proper diet, substrate, heat, lighting, humidity, and enrichment. Trained undergraduate Animal Discovery Room (ADR) student assistants, with the help of teen volunteers, conduct daily checks of all animals, under the supervision of the ADR Manager. ADR assistants and interns are the first to notice any changes in the animals’ behavior or physical appearance. If there is a behavioral or physical change in an animal, it is monitored and may receive vet care depending on the severity of the situation. In order to monitor all of the ADR animals, we conduct monthly weight checks. New or sick animals are weighed weekly and monitored closely to ensure that they are adjusting well and staying healthy. When needed, we administer medication or provide other special care recommendations suggested by our knowledgeable veterinary staff.

UC Berkeley Office of Laboratory and Animal Care (OLAC) veterinarians provide care for all our animals according to campus animal care and USDA regulations. Veterinarians are available 24/7 to provide quality veterinary care and advice. They do routine checkups on all of the animals, as well as operations and x-rays, and provide other veterinary services.
