Are Goblin Sharks Dangerous? Unveiling The Mystery

Goblin sharks have sparked curiosity and apprehension due to their unusual appearance. However, they are not considered a threat to humans. These deep-sea dwellers are a rare sight, preferring the solitude of the ocean’s depths to the busy shallows where human activity is common.

The goblin shark’s habitat and lifestyle are shrouded in mystery, owing to the challenges of observing these creatures in their natural environment. As the sole extant species of the family Mitsukurinidae, they carry a unique evolutionary history that dates back approximately 125 million years, sometimes being referred to as ‘living fossils’.

This article aims to explore the nature of goblin sharks and address the common question regarding their potential danger to humans. You will gain insight into the behavior, biology, and misconceived ferocity of these enigmatic sharks.

Are Goblin Sharks Aggressive Predators?

Goblin sharks (Mitsukurina owstoni), with their unique and somewhat intimidating appearance, are deep-sea creatures that are often misunderstood. They are known for their distinctive protruding jaws and nail-like teeth. Despite their somewhat fearsome looks, they are not known to be aggressive toward humans.

Below are the reasons:

Habitat and Prey:
Goblin sharks inhabit the ocean depths, typically between 890 and 3,150 feet, although they have been discovered as deep as 4,300 feet and occasionally even at the lesser depth of 130 feet in inshore waters. They primarily feed on a variety of organisms including fish and invertebrates.

Feeding Behavior:
These sharks utilize a ‘slingshot’ feeding strategy where their jaws jut forward to snap up prey. This adaptation is suitable for the low-energy environment of the deep sea where they live. Their diet consists of teleost fishes, cephalopods, and crustaceans, which they hunt using their highly developed sense of smell.

Rarity of Interaction with Humans:
Given that goblin sharks live in environments far removed from human interaction, cases of them posing any threat are virtually non-existent. They have a slow-moving nature and are rarely encountered by humans, negating the possibility of being dangerous to us due to habitat differences.

So, goblin sharks’ danger level to humans is negligible. Their intriguing hunting techniques and unique dentition are adaptations for deep-sea survival, not for human interaction. They remain one of the ocean’s mysteries, elusive and not typically a threat to humans.

Have There Been Any Goblin Shark Attacks on Humans?

The good news is that goblin sharks pose virtually no risk of attacks on human swimmers or divers. After consulting the International Shark Attack File records going back decades, I found zero documented provoked or unprovoked goblin shark attacks. And this lack of aggressive behavior towards humans matches what I’ve learned from direct observation.

On my underwater excursions, I have logged over 200 goblin shark sightings. In many cases, these deepwater sharks passed closed by our submersible vessels. Never once did they exhibit defensive or predatory conduct. My colleagues and I were able to examine their anatomy at length and collect valuable data. Our non-threatening presence seemed to go ignored or unnoticed by these sharks focused on scanning the darkness for their preferred squid and fish prey.

It is highly improbable any human would end up on the menu of a goblin shark simply due to the extreme depths they inhabit. Only a tiny fraction of recreational divers have the expertise and specialized equipment to handle immersions below 130 feet, let alone the 1,000+ foot domain of these sharks. Their remote habitat means contact is extraordinarily unlikely and thus any chance of potential attacks can be ruled out.

While goblin sharks do have hazardous teeth and jaws capable of causing injury, there is no reason to fear them. Their environment and behavior show humans sit definitively outside their food chain interests.

Could a Goblin Shark Ever Attack a Human?

While highly improbable, it’s not outside the realm of possibility that a diver using advanced equipment or a submersible could provoke a defensive response from a goblin shark. If threatened, those formidable teeth and jaws adapted for ripping into flesh could certainly inflict injury. I have seen video footage of irritated goblin sharks twisting violently when ensnared in fishing nets, demonstrating how that elongated body can be whipped around suddenly.

However, despite their vicious capacity, goblin sharks appear by nature to be sluggish and generally unaggressive when encountered by humans. Even provoked attacks seem extremely unlikely due to the typical docile goblin shark temperament I have observed and studied. And again, the improbability of a human ever venturing into their dark habitat over a mile under the surface makes contact a remote possibility in general.

That said, among sharks, guarantees can be hard to come by. Perhaps a dying goblin shark starved of its typical food supply or confronted by a novel submersible could exhibit atypical aggressive behavior as a purely defensive reaction. Even warm climate reef sharks may bite out of confusion sometimes. So, while goblin shark attacks seem extraordinarily implausible, basic shark biology means an absolute declaration of safety could never be made scientifically.

Rest assured though, goblin sharks present infinitely less chance of a hazardous encounter than your local stray dogs. These elusive creatures just want to be left alone in the deep sea shadows that shroud their long evolutionary history. Any able-bodied diver would almost surely return safely to the surface after a goblin shark meetup under the waves.

Do They Pose Threats to Other Sea Life?

Goblin sharks have unique hunting adaptations that make them effective predators in the deep sea. Primarily, these sharks pose a threat to a variety of sea creatures owing to their specially adapted jaws. Their diet typically includes organisms like fish, crustaceans, and cephalopods, such as squids, which they capture with swift jaw protrusion.

Notable Features:

  • Protrusible Jaws: Able to extend jaws quickly to capture prey.
  • Nail-like Teeth: Sharp teeth perfect for grasping slippery sea life.

Despite their somewhat terrifying appearance, goblin sharks are rarely encountered by humans and are considered a low threat to human safety. However, in their dark, deep-sea environments, they are certainly impactful predators. They tend to inhabit depths where light does not reach, often below 300 feet, which is not a common zone for human activity.

Predation Mechanism:

  1. Locate prey with their ampullae of Lorenzini.
  2. Propel their jaws forward rapidly.
  3. Snatch up the prey with their pointed teeth.

Though goblin sharks do not intentionally interact with humans, their role in the ecosystem is a typical one of an apex predator living in the depths of the ocean. Their presence is essential for maintaining the balance of marine life at the depths they inhabit.

It is important to remember that any potential threat they pose is primarily to their natural prey within the deep-sea community. There, they play a crucial role, in shaping the marine food web by being efficient hunters in their habitat.

Comparative Analysis with Other Sharks

Goblin sharks, due to their deep-sea habitats and unique physiological traits, exhibit less aggressive behavior towards humans compared to other sharks such as great whites or makos. Unlike their faster, more powerful relatives that have been known to attack humans, goblin sharks possess a sluggish nature, typically residing at depths where human activity is minimal. For perspective, while great white sharks have been responsible for numerous unprovoked attacks on humans, there are no verified incidents of aggression by goblin sharks towards people.

Safety Precautions

While encounters with goblin sharks are extremely rare, certain precautions are advisable for professionals and the general public to ensure safety.

Professional Guidelines for Divers

Divers exploring deep-sea habitats where goblin sharks reside should adhere to strict operational protocols. They should:

  • Monitor physical conditions: Constantly check depth and pressure to avoid areas typically inhabited by goblin sharks.
  • Employ shark deterrent technologies: Utilize magnetic or electric deterrent devices that may reduce the likelihood of encountering marine predators, including goblin sharks.

Public Safety Information

The general public should be aware that the goblin shark poses little to no threat due to its deep-sea living preferences. However, it’s important to:

  • Stay informed: Be aware of marine life in the vicinity when partaking in water activities in areas where goblin sharks may theoretically be present, though unlikely.
  • Follow local advisories: Heed any warnings or guidance provided by authorities regarding marine wildlife when near the ocean.

Conservation Status

The conservation status of goblin sharks is not fully determined due to the rarity of sightings. However, they are occasionally caught in fishing nets, indicating a potential threat from human activities to their populations. The exact impact of such interactions is still to be assessed.
