The Sea of Cortez, with its rich waters and stunning biodiversity, is home to some of the most captivating marine species in the world. Among the most iconic are whale sharks and sea lions, two animals that enchant visitors with their size, grace, and playfulness.
Yet, despite their popularity, many myths and misconceptions surround these creatures. Some of these myths are harmless, while others could negatively impact conservation efforts or tourist interactions. In this blog post, we’ll debunk the top five whale shark myths, and sea lion myths, separating fact from fiction so that you can appreciate these animals even more on your next adventure to the Sea of Cortez.
Myth #1: Whale Sharks Are Dangerous Because They Are Sharks
When people hear the word “shark,” they often think of sharp teeth, aggressive behavior, and danger lurking beneath the waves. This association with famous predatory sharks like great whites leads some to believe that whale sharks must be dangerous too. However, this couldn’t be further from the truth.
Fact: Whale sharks are the gentle giants of the ocean. Though they hold the title of the largest fish in the sea, reaching lengths of up to 40 feet (12 meters) or more, they are filter feeders, not hunters. Whale sharks feed on plankton, small fish, and other microscopic organisms by filtering water through their enormous mouths. Despite their size, they pose no threat to humans, making them one of the safest large animals to swim alongside in the ocean. Snorkeling with whale sharks in the Sea of Cortez is a humbling and awe-inspiring experience, and there’s no need to fear these magnificent creatures.
Myth #2: Sea Lions Are Friendly All the Time
Sea lions, particularly those in the Sea of Cortez, have a reputation for being playful and curious. Tourists often expect to encounter friendly sea lions eager to interact and engage in water acrobatics. While it’s true that sea lions in the Sea of Cortez can be inquisitive and even approach swimmers, there’s more to their behavior than just playfulness.
Fact: Sea lions can be both playful and territorial. While many sea lions, especially younger ones, are known for their friendly demeanor and may even come close to swimmers out of curiosity, it’s important to remember that they are wild animals. Adult males, in particular, can be quite territorial, especially during the breeding season. They are known to aggressively defend their territory from perceived threats, including boats or humans that get too close to their resting areas. In fact, activities around sea lion rookeries in La Paz are closed from June-August for the mating season, to avoid encounters with territorial males.
It’s essential to approach sea lions with respect and care. On guided snorkeling tours, knowledgeable guides will teach you how to interact with sea lions safely, ensuring that you enjoy the encounter without disturbing the animals or putting yourself at risk.
Myth #3: Whale Sharks Are Whales
One of the most persistent myths surrounding whale sharks is that they are, in fact, whales. The confusion stems from the name, their massive size, and perhaps their filter-feeding behavior, which is similar to that of baleen whales like blue or humpback whales.
Fact: Whale sharks are not whales; they are sharks. The name “whale shark” can be misleading, but these creatures are a “whale of a shark” and not the other way around! They are the largest species of fish in the world, their skeletons are made of cartilage rather than bone, they breathe through gills, and they have multiple rows of tiny teeth—though they don’t use them for feeding.
The term “whale” in their name simply refers to their enormous size, not their biological classification. Knowing the difference helps in understanding their behavior and biology better, which adds depth to your experience when you swim with them.
Myth #4: Sea Lions Are Just Like Seals
People often confuse sea lions and seals. While it’s true that they are both members of the pinniped family (which also includes walruses), there are important distinctions between the two.
Fact: Sea lions and seals are quite different in terms of appearance, behavior, and physiology. One of the most noticeable differences is that sea lions have external ear flaps, while seals do not—they only have small holes for ears. Sea lions are also more agile on land due to their larger, rotating front flippers, which they can use to “walk” on land, whereas seals tend to wriggle on their bellies. This makes sea lions more social and active on rocky shores. Where they can often be seen sunbathing or climbing around, unlike seals that prefer a quieter, more solitary lifestyle.
When you visit the Sea of Cortez and witness sea lions in action, understanding these differences enhances your appreciation of their unique adaptations to life both in and out of the water.
Myth #5: Whale Sharks Are Social Creatures
Many people imagine whale sharks as social animals, gathering in specific places to feed together. This perception leads to the belief that whale sharks interact with each other or form groups like other marine animals, such as dolphins or whales.
Fact: Whale sharks are known to gather in large numbers when conditions are right. For example, whale sharks congregate in areas with abundant plankton blooms, which serve as feeding hotspots. These gatherings, known as “aggregations,” can sometimes involve dozens or even hundreds of whale sharks, all feeding in the same area. One of the most famous aggregation sites is in the Sea of Cortez near La Paz. However, whale sharks do not exhibit the same complex social structures as dolphins or whales, and while they aggregate, they do not really interact.
Conclusion
Whale sharks and sea lions are two of the most fascinating creatures in the Sea of Cortez, drawing visitors from around the world to witness their beauty and grace. However, myths and misconceptions can cloud our understanding of these animals, leading to misunderstandings or even harmful behavior. By debunking these common myths, we hope to inspire a deeper appreciation for whale sharks and sea lions, leading to respectful, informed, and conservation-minded interactions .
