Mocca, the Colombian Red-tailed Boa
Mocca is the largest snake we have in our animal colony. She’s approximately 13 years old, is almost 8 feet long, and weighs about 28 pounds. It usually takes two staff to pick her up, but once one person gets her wrapped around their waist, Mocca can hang on as if she were wrapped around a tree and hold herself up. Despite her intimidating size, she is a gentle giant and can be quite shy, preferring to spend much of the day curled up resting or observing visitors from the security of her hiding places. She is a boa constrictor and will wrap around her prey, such as a large rat, to devour it whole. She uses her strong muscles to swallow her prey, slowly digesting it. She only needs to eat once every three weeks! Mocca can also be a little bit of a picky eater, and sometimes takes up to an hour to decide she finally wants to eat a rat. At the Hall, we only feed previously frozen rats and mice, which we carefully defrost, warm up, and rub in a bedding that smells like a live rodent. This way we help protect our snakes from possible harm from a live rodent that might not be too keen on being eaten!
Visit Mocca and all our Animal Ambassadors on weekends and select holidays in the Animal Discovery Room from 1:30 to 4:00 p.m.
There are a number of animals in the Animal Discovery Room that have served us well for many years and are now ready to retire from the world of education. In some cases, we have more of one species than we really need. We are looking for permanent homes for these wonderful animals. A small adoption fee helps ensure that each animal goes to a family that is ready to take on the responsibility of adoption. Here is a current list of adoptable animals as well as criteria for adopting them.
Criteria For Adopting
- You must set up a time with the Animal Discovery Room Manager to talk about species-specific enclosure requirements and the animal's husbandry needs and history*. See Contact Us page for general contact information.
- You must provide your own enclosure with proper set up and food for the animal prior to picking it up.
- You must pay the $15.00 adoption fee for most animals. Mice are a $5.00 flat adoption fee, regardless of how many are adopted at once. Rats are $5.00 each.
*Note: Not all adoptable animals are recommended for households with small children.
Make a Donation
We house more than 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.
This October we’ll be unveiling our new pond-turtle tank! This beautiful 300-gallon tank was 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 while they chase live fish and even each other.
We Care About Our Animals
Special care is taken to ensure that all of our animals are housed correctly, with the proper substrate, heat, light, humidity, and enrichment. Undergraduate Animal Discovery Room (ADR) helpers, with the assistance of teen interns, conduct daily checks of all ADR animals. Helpers 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 to ensure that they are adjusting well and staying healthy. When needed, we administer medicine, supplied by our veterinarians.
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.
