Introduction to Marine Mammal Behavior
Marine mammal behavior is incredibly diverse, influenced by their species, environment, and individual personalities. Understanding their natural behaviors is the foundation of good animal husbandry. This knowledge allows trainers to recognize signs of stress, illness, or well-being, and to develop effective training and enrichment programs.
Key areas we will explore include:
- Social Behaviors: How they interact with each other.
- Foraging Behaviors: How they find and eat food.
- Resting Behaviors: How they sleep and conserve energy.
- Communication: How they communicate (vocalizations, body language).
Social Behaviors
Social behaviors vary significantly between species. For example, some dolphins live in complex social groups called pods, exhibiting behaviors like:
- Play: Jumping, chasing, and object manipulation.
- Affiliation: Physical contact, rubbing, and synchronized swimming.
- Cooperation: Working together to solve problems, like gathering food.
- Dominance hierarchies: Specific social structures.
Other marine mammals like seals might be more solitary except during breeding season. Observing social behaviors helps trainers understand their social needs and provide appropriate enrichment.
Foraging Behaviors
Foraging behaviors relate to how marine mammals find and consume food. These behaviors are essential for survival and can vary widely depending on the species and their environment. Examples include:
- Hunting: Pursuing and catching prey (fish, squid, crustaceans).
- Feeding: Consuming the prey.
- Exploration: Searching for new food sources.
Understanding foraging behaviors helps trainers to provide appropriate diets, design feeding stations, and create opportunities for natural foraging behaviors in managed settings. This is often replicated in training with food as the primary reward.
Resting Behaviors and Conservation of Energy
Marine mammals have different methods of resting depending on their environment and species. This is often crucial for energy conservation. Some examples include:
- Surface resting: Dolphins and whales might 'log' or 'spyhop' while sleeping near the surface.
- Bottom resting: Seals often rest on the ocean floor or on land.
- Breathing patterns: Marine mammals have to consciously control their breathing, and this changes when they are resting, allowing the trainer to identify their state.
Understanding these resting behaviors helps trainers provide suitable resting areas and recognize signs of stress or lack of sleep.
Communication: Sounds, Body Language, and More!
Communication is vital for marine mammals, helping them to interact, navigate, and maintain social bonds.
- Vocalizations: Whistles, clicks, and other sounds convey information.
- Body language: Posture, gestures, and facial expressions (in species that can make them) signal intentions and emotions. Specific body postures help indicate health and wellbeing.
- Touch: Physical contact, like rubbing and playful interactions, strengthens social bonds.
By observing these communication methods, trainers can develop a deeper understanding of the animal's needs and emotional state.

Day 3: Marine Mammal Behavior - Extended Learning
Building on the Basics
Today, we're expanding your knowledge of marine mammal behavior beyond basic identification. We'll explore how these behaviors are influenced by environmental factors, and how you can use this understanding to improve animal welfare and enhance training techniques.
Deep Dive: Behavioral Ecology and Context
Understanding marine mammal behavior isn't just about identifying what they do; it's about understanding why they do it. This involves considering their behavioral ecology – the study of the ecological and evolutionary basis for animal behavior. Key concepts to consider include:
- Environmental Influences: Behavior is heavily influenced by their environment. Consider the effects of:
- Enclosure Size/Complexity: How does space and enrichment impact foraging, social interaction, and resting behaviors?
- Water Quality: Does poor water quality influence breathing patterns or activity levels?
- Social Group Dynamics: Are there hierarchies? How does the presence or absence of specific individuals alter behavior?
- Adaptive Significance: Many behaviors serve a purpose for survival and reproduction. Understanding this helps interpret unusual behavior and identify potential welfare concerns.
- Communication: Marine mammals communicate through vocalizations, body language, and tactile interactions. Understanding these forms of communication is crucial for effective training and building positive relationships.
Bonus Exercises
Exercise 1: Observation Log
Choose a marine mammal species (e.g., dolphins, sea lions). Watch a video of the species in a zoo, aquarium, or natural environment. Keep an observation log. For 30 minutes, note down:
- Specific behaviors observed (e.g., swimming, resting, playing, vocalizing).
- Potential triggers for these behaviors (e.g., presence of food, another animal, change in environment).
- How these behaviors might relate to the animal's needs (e.g., social interaction, foraging, rest).
Exercise 2: Case Study Analysis
Research a case study or article about a marine mammal in a captive environment exhibiting unusual or undesirable behaviors (e.g., repetitive behaviors, aggression). Identify the potential environmental or social factors contributing to these behaviors. Propose how you would approach addressing these issues, considering enrichment, social adjustments, and training techniques.
Real-World Connections
Understanding behavior is essential in the following ways:
- Welfare Assessments: Behavioral observations are fundamental in assessing an animal's welfare state. Changes in behavior (e.g., lethargy, increased aggression, repetitive actions) can indicate stress or illness.
- Enrichment Design: Knowledge of natural behaviors allows trainers and caregivers to design effective enrichment programs (e.g., puzzle feeders, novel objects, social opportunities).
- Training Effectiveness: Understanding what motivates each animal (e.g., social interaction, food, play) allows trainers to tailor training programs and reinforce desired behaviors.
- Conservation Efforts: By observing behavior in captive animals, you can gain insights that can inform conservation efforts for wild populations. For example, studying foraging behavior in captivity can help conservationists understand the impact of habitat loss on wild populations.
Challenge Yourself: Advanced Observation
For a more advanced exercise, attempt to create an ethogram – a detailed catalog of behaviors observed for a specific species. This requires creating a list of well-defined behaviors and recording the frequency, duration, and context of each behavior over an extended observation period.
Further Learning
Continue your exploration with these topics:
- Ethograms and Behavioral Budgets: Learn about different methods of quantifying and analyzing behavior.
- Stress and Welfare in Captive Animals: Explore how environmental stressors impact animal well-being.
- Specific Training Techniques: Learn about various training methodologies that utilize behavioral principles.
- Animal Communication: Research the different forms of communication utilized by marine mammals, particularly in the context of training.
Consider exploring scientific publications, documentaries, and attending workshops or online courses on marine mammal behavior and animal training.
Interactive Exercises
Behavioral Observation Worksheet
Download and print a simple observation worksheet. Spend 15-20 minutes observing videos or, if possible, live marine mammals (safely and responsibly). Note down as many different behaviors as you can, categorizing them into social, foraging, or resting. Share your observations and insights with your classmates.
Behavioral Matching Game
Match common marine mammal behaviors (e.g., spyhopping, tail slapping, porpoising) with their descriptions (e.g., breaching the surface to look around, hitting the water surface with their tail, jumping high out of the water). This game can be played as a flashcard activity, either online or with physical cards, reinforcing behavior identification.
Scenario Analysis
Read the following scenario: * *A trainer notices a dolphin is spending excessive time near the bottom of the pool and not interacting with the other dolphins. The dolphin also seems to be listless during training, and is not accepting food as readily as before.* Analyze the scenario. What behaviors did the trainer observe? What might these behaviors suggest? What should the trainer do next to ensure the dolphin’s welfare? This is best carried out in a group and discussed with your classmates.
Practical Application
Imagine you are a new marine mammal trainer. You're observing a dolphin named 'Echo' in a new habitat. Describe three different behaviors you would expect to see from Echo, what they might indicate about the dolphin's well-being, and how you would react if one behavior looked abnormal (like a loss of appetite).
