Introducing Animals: Kangaroos and Kin

They're famous for hopping, but how much do you know about the group of marsupials known as the macropods? What's the difference between a wallaby and a kangaroo? And what on earth is a pademelon? (Hint: it's not a fruit!)

Keepers, interpreters, guides, and docents can explore the fascinating life of macropods—kangaroos and their kin—as the San Diego Zoo Global Academy presents the newest module in Introducing Animals, our series about animal species and other taxonomic groups. Introducing Animals: Kangaroos and Kin explores the behavior, ecology, reproduction, and conservation of these unique animals.

Hop right into this comprehensive introduction to their fascinating world "Down Under." Remarkable images show them in ways you've never seen before, and video provides insights into their behavior. Interactivity sprinkled throughout the modules engages participants in the learning process, and questions at the end of each section ensure that they have mastered fundamental concepts before they move on. The Kangaroos and Kin module takes about 90 minutes to complete, although participants progress at their own pace and may repeat the entire course or sections of the course as many times as they like. Introducing Animals: Mammals is a recommended prerequisite.

This module can easily be integrated into your current training program. Providing online modules that team members can complete anywhere and at any time overcomes one of the major challenges of training: getting all participants together in one place at one time. At the San Diego Zoo and Safari Park, participants complete online modules on their own before attending group training programs. They are able to master key vocabulary and concepts, giving them a solid foundation that allows them—and their trainers—to make the most of in-class and on-site training.

The module is an awesome resource for interpreters, but it offers insights to veteran animal keepers too, providing a glimpse of natural history that helps keepers address husbandry concerns. It addresses common questions and provides an up-close exploration of what macropods are all about. Whether you've worked with these animals for years or you're a brand-new interpreter or docent, the module will equip you with a better understanding of these amazing animals.

The Kangaroos and Kin module joins Lemurs, Penguins, African Penguins, Hamadryas Baboons, Old World Monkeys, Mammals, Birds, Giraffes, Rhinoceroses, Elephants, Cats, Orangutans, Great Apes, Lions, Cheetahs, Polar Bears, Giant Pandas, Tigers, and Gorillas in the Introducing Animals series. (Look for a reptile module coming later this year!)

Texas Association of Museums and San Diego Zoo Global Academy Collaborate

Texas Association of Museums logoSan Diego Zoo Global's facilities are accredited by the American Association of Museums, so it is not an infrequent event when San Diego Zoo Global Academy talks with museums about online training. The question is often "how can we do more with museums?" With that in mind, San Diego Zoo Global Academy was introduced to the Texas Association of Museums, and together we talked about possibilities for collaboration. Here is what we are thinking about: the Texas Association of Museums was envisioning creating TAM Talks for their members, and the Academy is envisioning using our platform to share more museum content with museums. A TAM Talk will be a 10-minute talk about museum topics by museum experts, for a museum audience. Given that, we are going to assist the Texas Association of Museums with creating TAM Talks, making them available to TAM members, and then also making those talks available to museums outside of Texas.

The Texas Association of Museums recently invited the Academy to its annual meeting in Houston. We want to take this opportunity to thank TAM, and their attendees, for making us feel so welcome, and for their enthusiasm about this collaboration and their great interest in the TAM Talk concept. We will share more as we build on this great start!

Getting Better All the Time:
A Responsible Framework for Utilizing Third-party Reviews to Advance Animal Welfare and Provide Greater Transparency

Excellence Beyond Compliance logoBy James F. Gesualdi

To keep ahead, each one of us, no matter what our task, must search for new and better methods—for even that which we now do well must be done better tomorrow.
—James F. Bell

There is always a way forward. A better way. And a way to change the trajectory of circumstances, events, and factors like public perception and the public trust, which remain vital considerations to the zoological community. The way begins with us and how we view and act upon our ability to change ourselves, our organizations, the zoological community, and the use of external controls like the Animal Welfare Act (AWA) regulations and inspections, and accrediting association standards, guidelines, and other reviews.

Recently, the United States Department of Agriculture, Animal and Plant Health Inspection Service, Animal Care unit completed its listening sessions on the concept of using "third-party inspections," such as those associated with accreditation and certification, to factor into determining the frequency of agency inspections. The prospect of considering third-party or non-agency "inspections" is part of the agency's ongoing examination into the potential reallocation of agency resources to more effectively administer the AWA. The listening sessions, press releases, statements, and media coverage all suggest that there is great concern over supplanting agency inspections, and strong support for the agency's current inspection model. Other potential concerns relate to qualifications of the third-party reviewers. The comment period closed March 21, 2018. For more information on documents and comments, see regulations.gov/docket?D=APHIS-2017-0102.

Official federal agency inspections produce formal inspection reports generally available online and by request. This also establishes a record of compliance history, as well as a basis for enforcement action, if warranted. There is simply no substitute for such inspections.

As noted in Excellence Beyond Compliance, and in previous columns, the AWA is best viewed as a starting point rather than an ending point for animal welfare-related efforts. That starting point or baseline should remain (but can certainly be improved upon). With this in mind, voluntary and novel use of third-party "reviews" can provide a great service to all stakeholders concerned about the well-being of the animals in our care.

Given the effort and time invested in presenting and critiquing the concept, here are some preliminary ideas to make the most of the knowledge gained from this process to date, in order to continuously improve regulatory efforts and animal welfare using third-party "reviews" (but not as a substitute for agency inspections).

  1. Agency AWA inspections should continue (and be improved).
  2. Third-party "reviews" (though sometimes referred to as inspections in the context of accreditation and certification) should be recognized as important supplemental means of assessing and improving current conditions.
  3. Third-party reviews should be encouraged and voluntarily employed in addition to, but not a substitute for, agency inspections.
  4. It must be understood that any third-party reviewer(s) must be fully qualified for the task at hand, including possession of appropriate credentials, experience, and expertise.
  5. Following third-party reviews—including but not limited to those for accreditation and certification—focusing on improvements or incidents, the following information should be proactively and voluntarily disclosed:
    1. Identification of good practices worthy of consideration and potential adoption at other facilities.
    2. Commitments to undertake and implement improvements, e.g., animal welfare or other enhancements, perhaps in the form of an improvement or advancement plan.

Such use of third-party reviews would bolster but not replace agency inspections, positively reinforce use of voluntary third-party expertise, further disseminate good practices to enhance animal welfare, support and reinforce continuous improvement, and provide greater transparency and accountability for all involved. These are all things the public demands and values. Most importantly, such a responsible framework for greater use and disclosure relating to third-party reviews demonstrates how we live our commitment to the well-being of the animals entrusted to our care.

Teh Aquarium Vet logoSomething Fishy Is Going On
By Dr. Rob Jones, "The Aquarium Vet"

In my last article, we discussed osmoregulation in freshwater fish. Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids to maintain the homeostasis of that organism's body water.

This month, we look at marine fish. Remember that the internal environment of a fish is between 8 and 10 parts per thousand (ppt) salt (humans are 9 ppt, for comparison). Seawater is 35 ppt (although in some parts of the world it may be as high as 40 ppt). Marine fish are, therefore, in a solution that is higher in salt levels than their body—i.e. hyperosmotic (or hypertonic) to the fish. This means that they are constantly having water leave their body via the massive surface area of the gills. As such, there is a constant threat for them to become dehydrated or hypovolemic (a condition of decreased blood volume). So, how do marine fish combat this loss of water that is constantly migrating outward?

Marine fish avoid dehydration by drinking lots of seawater to replace the H2O leaving the gills. They drink up to 20 percent of their body weight every day (so the saying "drinks like a fish" only applies if you are a marine fish!). The problem is that they are ingesting lots of salts, particularly sodium (Na+), potassium (K+), and chloride (Cl-). Specialized cells called chloride cells are present in very high numbers in the gills of marine fish. They use a lot of energy to actively excrete these excess ions from the body.

Marine fish can absorb sodium (Na+) and chloride (Cl-) across the oesophageal wall (partly a passive and partly an active process), and both water and all the monovalent ions are absorbed across the intestinal wall. Between 60 and 80 percent of the water and monovalent ions that are drunk will be absorbed this way. Only about 20 percent of the divalent ions (calcium Ca2+ and magnesium Mg2+) are absorbed across the intestinal wall, and the remaining 80 percent pass through and out in the feces. In marine fish, the intestinal lining is a very important osmoregulatory organ.

The kidneys in marine fish work to conserve water, and so produce very small quantities of urine. In fact, only 5 to 10 percent of the water drunk each day is actually excreted as urine. The kidney, however, is involved in the excretion of excess divalent ions (of the only 20 percent absorbed from the gut), as well as retaining the monovalent ions. The urinary bladder also plays an important role in water absorption and active sodium reabsorption to help maintain osmotic balance. A marine teleost's daily urine rate is about 1 to 2 percent of its body weight (compare this to a possible 15 percent for freshwater fish).

The diagram below provides a summary of osmoregulation in a marine fish.

It is for the above reasons that reducing the salinity of seawater is beneficial in reducing osmotic stress in marine fish during quarantine or any other stressful period.

I look forward to seeing some of you at the Regional Aquatics Workshop Conference RAW 2018 at The Florida Aquarium in Tampa, May 14–18. The Aquarium Vet will have a booth, so please drop by and say "G'day!"
