Lesson Content
Healthy Appearance: Skin and Coat
A healthy marine mammal's skin and coat are vital indicators of overall health. Generally, you should look for smooth, intact skin without excessive scaling, lesions, or discolorations. For example, a healthy dolphin's skin will be smooth and glistening, while a sea lion's coat will be sleek and shiny.
Examples:
* Healthy: Smooth, shiny skin (dolphin); Sleek, well-groomed fur (sea otter)
* Unhealthy: Lesions or wounds, excessive peeling, discoloration (redness, paleness), visible parasites (e.g., barnacles)
Breathing Patterns and Activity Level
Breathing should be regular and relatively effortless. The frequency varies depending on the species and activity level, but generally, it should be calm. Abnormalities include labored breathing (e.g., wheezing, rapid breathing), discharge from blowholes, and changes in buoyancy (e.g., struggling to stay afloat).
Activity level is also a key indicator. Healthy animals are typically alert, active (playing, swimming, interacting), and exhibit normal behaviors for their species. Watch for lethargy, lack of interest in food or interaction, and unusual postures (e.g., listlessness).
Examples:
* Healthy: Regular, quiet breaths; Energetic swimming and play
* Unhealthy: Labored breathing (gasping); Lethargy (lying still for extended periods); Loss of appetite
Observational Techniques and Importance of Documentation
When observing marine mammals, take detailed notes. This can include the animal's name, the time of observation, and a specific description of what you see. Note any changes compared to previous observations. The more detailed your observations, the better you can inform veterinary staff of any possible issues. Consider drawing diagrams or taking photographs to further enhance your notes. The purpose of detailed documentation is to provide valuable information to medical staff to diagnose and treat health problems.
Key areas to observe: Skin condition, breathing, posture, activity, appetite, and interactions with other animals (if applicable).

Day 2: Marine Mammal Trainer - Health & First Aid (Extended)
Welcome back! Today, we're building on what you learned about observing marine mammal health. We'll dive deeper into specific visual cues, understand the impact of environmental factors, and practice our observational skills.
Deep Dive Section: Beyond the Basics - Context Matters
While identifying the 'normal' appearance and behaviors is crucial, understanding the context is equally important. Think of it like being a detective. Just because a seal isn't behaving *exactly* like others doesn't *automatically* mean something is wrong.
Consider these factors when assessing an animal:
- Species Differences: Different marine mammal species have varying 'normals'. For example, a sea otter's fur naturally has more air trapped within, giving them their characteristic fluffy appearance. Comparing an otter's fur to a dolphin's skin would be misleading.
- Age & Life Stage: A young pup will exhibit different activity levels than a mature adult. Similarly, a pregnant female might have altered behavior.
- Environmental Conditions: Water temperature, time of day, and presence of other animals (including predators or other enclosure mates) can influence an animal's behavior. A dolphin might be more active during feeding time or when it's interacting with enrichment items.
- Prior History: If you know an animal has a previous health condition, you may be more alert to certain signs. Knowing an animal's medical history will help you determine its baseline.
By considering these factors, you can make a more informed assessment, avoiding unnecessary alarm and quickly identifying legitimate problems.
Bonus Exercises
Exercise 1: Photo Analysis
Examine the following photos (links provided – you may need to find your own, for example by searching images of specific marine mammals) and describe the animal's:
- Skin and coat condition
- Breathing pattern (if visible)
- Activity level (based on what you can see)
- Any potential concerns. Justify your observation based on the context of the picture.

Exercise 2: Case Study – The Curious Case of the Slow Swimmer
A trainer notices a bottlenose dolphin swimming slowly and appearing less active than usual. The dolphin's appetite is normal, and it interacts with trainers as usual. Its skin looks smooth and healthy. Consider these additional facts:
- It's the breeding season.
- The water temperature is slightly cooler than usual.
- The dolphin is normally one of the most energetic in the pool.
What might be some possible causes? What further observations would you make? What would you report, and to whom?
Real-World Connections: Every Observation Counts
Your observations are the foundation of good animal care. Here's how it translates into the real world:
- Early Disease Detection: Subtle changes in behavior or appearance can be early indicators of illness, allowing for prompt veterinary intervention, which increases the likelihood of a positive outcome.
- Effective Training Programs: Understanding an animal's baseline behavior helps trainers recognize stress signals and adapt training methods to ensure the animal's well-being.
- Research and Conservation: Data collected by trainers contributes to scientific understanding of marine mammal health and behavior, supporting conservation efforts.
- Teamwork: Clear and concise communication of your observations is critical. It involves everyone, from senior trainers to veterinarians, working together.
Challenge Yourself: The Observation Log
Create a simple observation log template. Include sections for:
- Date and Time
- Animal's Name/Identification
- Observed Behaviors (Detailed Description)
- Skin/Coat Condition
- Breathing Pattern
- Activity Level
- Environmental Factors (Water temp, Weather, other Animals)
- Any Concerns (with a brief explanation)
- Trainer's Name
Practice using this template during your observations. This will enhance your skills and assist you in developing your documentation skills.

Interactive Exercises
Image Recognition: Spot the Difference!
Examine a series of images (provided by the instructor, or using online resources) of marine mammals. Some images will show healthy animals, and others will show signs of illness or injury. For each image, identify the key observations that led you to your conclusion. Explain what makes them unhealthy, and how they differ from the images of healthy marine mammals.
Behavioral Observation Simulation
Watch a short video clip (provided by the instructor) of marine mammals in a pool or enclosure. While watching, take notes on the animals' behaviors, including breathing, activity, and social interactions. Then, compare your notes with another student or the instructor to discuss and compare observations. Discuss any subtle signs of illness or injury, and how to report any findings.
Observation Checklist Creation
Develop a checklist that marine mammal trainers can use to observe a common marine mammal species in their care (e.g., dolphins, sea lions, otters). The checklist should include areas to record observations on skin, breathing, activity level, appetite and interactions with other animals. Create a system for rating the severity of the findings (e.g., normal, mild, moderate, severe), and guidelines for what level needs to be reported to a supervisor.
Practical Application
Visit a local aquarium or marine park (if available) and observe the marine mammals. Practice using your observational skills to identify signs of health and illness. Take detailed notes, and then compare your observations with an experienced trainer or veterinarian.
Key Takeaways
Healthy skin and coat are smooth and intact; watch for lesions, discoloration, or parasites.
