As a marine biologist with a keen interest in the behavior and ecology of marine species, I can provide an insightful response to your question regarding shark-whale interactions.
Sharks are apex predators in the ocean, known for their diverse diets and hunting strategies. Whales, on the other hand, are massive marine mammals that occupy various niches within the marine ecosystem. The relationship between sharks and whales is complex and can vary greatly depending on the species of shark and whale involved, as well as the environmental context.
Do sharks attack whales? The answer isn't straightforward. It's essential to recognize that sharks are not a monolithic group; they encompass a wide range of species, each with its own set of behaviors and dietary preferences. Similarly, whales are a diverse group, including baleen whales that filter feed on tiny plankton and krill, and toothed whales like orcas that are known for their predatory prowess.
Predation and Scavenging: In general, sharks are opportunistic feeders. They will attack and consume prey that they can overpower. However, attacking a healthy adult whale is not a common occurrence for several reasons. First, whales are much larger and stronger than sharks, making them formidable opponents. Second, the energy expenditure required to take down such a large prey might not be worth the nutritional gain for most shark species. That said, sharks may indeed attack whales if the whale is injured, weakened, or already dead. In these cases, sharks act as scavengers, taking advantage of an easy meal.
Orcas and Sharks: Orcas, or killer whales, are a special case. They are known to prey on sharks, particularly great whites. Orcas are highly intelligent and social predators that hunt in groups, using coordinated strategies to take down their prey. They have been observed flipping sharks out of the water to disorient them and then consuming their internal organs, which are rich in nutrients.
Unprovoked Attacks: It's also worth noting that it is more common for whales and dolphins to engage in unprovoked attacks on sharks. This behavior is not fully understood but may be related to territorial disputes, competition for resources, or simply play behavior. Dolphins, in particular, have been known to harass sharks, often in a manner that suggests they are not doing it for food but rather for other reasons.
Size and Strength: The sheer size and strength of whales often deter sharks from engaging in direct confrontations. While some large shark species, like the great white, might be capable of taking on smaller or juvenile whales, such encounters are rare and not the norm.
Ecological Role: Both sharks and whales play crucial roles in their respective ecosystems. Sharks help maintain balance by preying on sick or weak individuals, thus contributing to the overall health of the marine environment. Whales, particularly baleen whales, are important in nutrient cycling, as they feed on the ocean floor and bring nutrients to the surface when they excrete.
In conclusion, while it is true that sharks may attack whales under specific circumstances, such as when the whale is injured or deceased, it is not a typical behavior. The dynamics between these two groups of marine animals are governed by a complex interplay of factors including size, strength, intelligence, and ecological roles. Understanding these interactions is vital for the conservation and management of both shark and whale populations.

They will if the whale is injured or already dead (or near death). In most cases sharks tend to run away from whales and wouldn't be able to fight them do to sheer size and strength. It is actually more common for whales and dolphins to attack a shark unprovoked, and orcas can eat sharks.
