The Gift of Grub: How Our Education Department Teaches with Teeth

Posted by in Feeding Our Animals

A clouded leopard skull model is great for teaching about carnivore teeth. Check out those canines!

There are many different types of teeth inside a mammal‘s mouth. This makes it easy for us to tell what a mammal eats, just by looking at its teeth. In the Education department, we teach about the three main groups of “eaters.” For these lessons, we use a variety of skull biofacts to show the different types of teeth.

Carnivores are animals that eat meat. They have large, sharp canine teeth for catching their food, with scissor-like molars to help tear meat into smaller pieces. Any of the cat skulls work well for this group, but my favorite is either a cougar or clouded leopard. They are smaller, so they are easier to take on programs, and the clouded leopard has huge canines. At the zoo, our mammalian carnivores include lions, cheetahs, and African wild dogs.

Take a look at the flat molars in the capybara's mouth. They're prefect for grinding plants.

Herbivores are animals that eat plants. They have flat, grinding molars with “clipping” teeth in the front. Some herbivores don’t even have teeth in the front! I like to use a model of a capybara skull for my sample herbivore. We have many members of this group at the Zoo, including giraffes, elephants, antelope, porcupines, and lemurs.

Once I’ve taught kids about these two types of teeth, I always bring out a “mystery skull.” I’ll carry it around, let them touch it, and then ask for votes on what the animal eats. Most of the time I can’t fool them; they figure out that it is a trick question and the animal is really an omnivore. Omnivores are animals that eat “everything” (that’s the “omni” in the word). Typically that means a combination of both plants and meat. These animals have some combination of both types of teeth. They typically have sharp, carnivore-like teeth in the front and flat, herbivore-like teeth in the back. Omnivores at the Zoo include raccoons, maned wolves, grizzly and Andean bears, and most of our primates.

The "mystery skull" omnivore I use: a raccoon!

Of course, there are lots of other “ivores” at the Zoo, like insectivores, piscivores, nectarivores, and frugivores. (That’s bugs, fish, nectar, and fruit eaters, if you wanted to know.) We’ll even teach about sanguinivores (blood eaters) from time to time, although we don’t have any on exhibit at the Houston Zoo. The next time you visit, imagine the teeth inside your favorite mammal’s mouth. They might reveal more than you think!

Give the Gift of Grub: Duplicating Nature

Posted by in Feeding Our Animals,Reptiles

The Houston Zoo is kicking off our holiday fundraising campaign – the Gift of Grub — to help defray the costs of caring for our animals and provide everything we need to keep them healthy and happy in 2011! This is a fun, new blog series that will tell the story of exactly what it takes to feed our furry, finned and fanged friends here at the Houston Zoo.  

In the commissary, besides all the produce we work with, we deal with lots of what’s known as feeder animals.  In the wild, while some animals, called herbivores, feed only on vegetation, some also eat insects and other animals (omnivores), while other species exist exclusively on meat (carnivores). To maintain optimum health, providing feeder animals is necessary. It occurs in nature, so it needs to occur here at the Zoo, where we, along with the keepers and our vet team, are committed to ensuring the best diet for each animal’s specific needs. 

Did you know we use 98,750 of rodents per year? We get mice and rats in different sizes, from 10 to 300 grams. Our large rodent order is delivered on Tuesday. These mice and rats are raised in a controlled environment and are disease free. We also obtain rabbits for are larger bird of prey, larger boas and pythons and at times some of our large cats.

 Throughout the year the Zoo holds special events and during that time we also have goat carcasses. Most recently, at our Feast for the Beasts event, our African lions and our Komodo dragon, enjoyed this special meal. 

We also use 18 million crickets, which also come in sizes from pinheads (newly hatched) to adult size crickets. Meerkats and reptiles thrive on them.  Birds, lizards, slow loris, marmosets, tamarins and other small mammals also eat crickets…. but during the months of April, May, June and July our biggest users of crickets are the Houston toads (there will be a whole blog post coming soon on those!).

Our crickets come from our supplier on Tuesdays and Thursdays. The delivery driver  has made comments a few times of escaped crickets in the back of the truck! 

Next time I will talk about more food items bought at the store that are used to supplement animal diets.
