Creature Feature: Goblin Shark
In this series, the Shark Trust will be sharing amazing facts about different species of sharks and what you can do to help protect them.
Written by guest contributor – Yolanda Evans.
Mysteriously slithering around the dark mesopelagic of the western Pacific, the glorious Goblin shark swims in search for their next meal. This illusive shark is one of the most unique-looking sharks to ever exist, having a long snout called a rostrum and protrusible jaws, hailing them their common name, Goblin. Their rostrum is covered with small pores called the ampullae of Lorenzini, jelly-filled pores in the snouts of many sharks that are able to pick up changes in the electro-magnetic field, for example the muscle contractions of nearby fish. However, these pores can only detect movement only a few inches in front of the shark!
In addition to their rostrum, these sharks poses and amazing ability to protrude their jaws out or their cartilaginous skull by something called slingshot feeding. This is when the jaws are shot forward, extending 8.6-9.4% of the Goblin sharks total body length. However, this fast jaw action also creates a powerful suction-known as a pharyngeal suction-forcing their prey deeper into their mouths.
While many sharks range from greys to blues to browns, this stupendous shark can be a very pale pink! However, this unusual colour is not from a pigment in their skin, but from the thinness of their skin! Their skin has such a great transparency that the oxygenated blood that flows in their capillaries-tiny blood vessels-causes what would be their grey skin, to become pink. This amazing ability might actually been an adaptation for the shark, they live 270m-1300 m deep, red light wavelengths cannot be seen, making the spectacular shark near invisible to both prey and predators!
Their scientific name, Mitsukurina owstoni, comes from the British naturalist Alan Owston who is credited with discovering the shark, and from Kakichi Mitsuriki, the Japanese scientist who identified and described the shark. While the English common name is only from their long rostrum, the direst translation into Japanese is Tengu-zame, base of the Tengu, a Japanese mythological half-man-half-bird who had red skin and a long nose, a comparison more fitting.
Despite their somewhat intimidating appearance, the Goblin shark is not an aggressive species, predating on mainly small bony fish, crustaceans, and cephalopods. Long slender teeth that protrude out from their jaws, appearing almost like blades, are perfect for clutching onto their prey. Nonetheless, the most threat they create towards humans is disrupting our internet as they are known to bite down onto submarine cables!
Like many other shark species, Goblin sharks main threat is by-catch from deep-sea longlining and deep-sea trawling. They are listed by the IUCN as least concern. Unfortunately, being relatively understudied, this may be incorrect as there is a very minimal amount of knowledge about the lives of these sharks. Leaving the question: what else is there to know about the truly incredible Goblin shark?
SCIENTIFIC NAME: Mitsukurina owstoni
FAMILY: Mitsukurinidae
MAXIMUM SIZE: Up to 3.8 meters (12.5 feet) in length
DIET: Feeds primarily on deep-sea fish, but also crustaceans and cephalopods
DISTRIBUTION: Goblin Sharks have a wide but patchy distribution, found in deep waters of the Atlantic, Indian, and Pacific Oceans.
HABITAT: Primarily found in the deep sea, typically between 200 and 1,200 meters (656 and 3,937 feet) in depth. They are occasionally seen at shallower depths, but are typically associated with steep slopes and canyons on the continental shelf and slope.
CONSERVATION STATUS:
Due to their deep-sea habitat and elusive nature, they are rarely encountered and little is known about their population trends. However, they are sometimes caught as bycatch in deepwater fisheries, and there is concern over the potential impacts of deep-sea mining activities on their habitat.

It’s time to catch up with 12-year-old Mia DaPonte, New England’s youngest ever female PADI Master Scuba Diver, in her latest blog for Scubaverse!
It’s still a little too cold to get in the water here in New England. I wish I had a drysuit! To get my ocean fix, I asked my mom to take me and my friends to the Biomes Marine Biology Center.
What is Biomes? It’s a rescue center near my house that’s home to all kinds of ocean animals—and they’re all local! It’s truly awesome to experience. There are so many cool creatures there, like skates, sharks, stingrays, horseshoe crabs, tropical fish, lobsters, seahorses, octopuses, and even some reptiles that were given up by their owners.
Darwin the turtle is always fun to watch. He’s huge and has his own home, but he also gets to wander around the place on his own when he feels like it!
They have lots of touch tanks. I got to touch sharks, turtles, and even hold a horseshoe crab! (There’s a little lip on the side of their shell where you can hold them—but don’t do this without permission! Their gills always need to stay in the water.) I also touched stingrays! They felt slimy but rough at the same time.
One of my favorite things to do is see the octopus and watch it play with the toys in its tank. I always check to see if any seahorses are pregnant and look for the babies when they’re born. The babies are kept in their own tank at first to stay safe, and then moved when they’re big enough.
We got lucky this time—there was a baby skate in a mermaid’s purse that was ready to hatch any day! It was in a special tank with a light. When you press the button, the light turns on so you can see the baby skate moving around inside the purse!
As our visit was ending, the owner, Mark, sat down with us and told us how he started Biomes. When he was 14 years old, he began rescuing sea animals. His love for the ocean started when he was young—just like mine! As he got older, he started a traveling business, bringing animals to classrooms and doing shows. Eventually, he turned it into something bigger, and now Biomes is a huge center full of rescued animals.
He told us that most of the fish and animals are rescued from fishing boats or the cold waters of New England—places where tropical fish wouldn’t survive the winter. They try to rescue babies whenever they can, so they have a better chance of adapting. Darwin the turtle actually hatched in Mark’s hand!
My mom gets a pass to Biomes every year because I love going there so much. There are always new animals to see and feedings to watch. One time, I even got to feed the octopus!
If you ever come to Rhode Island, you have to check out Biomes!
Every year, South Africa’s Sardine Run draws thousands of visitors, eager to witness one of the most spectacular marine wildlife events on the planet. Shoals of sardines stretch for miles, attracting a feeding frenzy of predators, including dolphins, seabirds, whales, and, of course, sharks. But while this natural wonder is a goldmine for ecotourism, some argue that it disrupts marine ecosystems or that shark tourism is an unnecessary risk.
The reality?
The Sardine Run doesn’t just showcase nature’s brilliance, it actively protects it.
A Predator Worth More Alive Than Dead
Sharks are the apex predators of the Sardine Run, and their presence is a major draw for divers, filmmakers, and tourists. But beyond the thrill, there’s a critical financial argument to be made: sharks are far more valuable alive than dead. A report by Oceana found that shark ecotourism generates hundreds of millions of dollars globally, while a single dead shark, caught for its fins or meat, is worth mere pennies in comparison.
According to Pew Trusts, reef sharks in Palau contribute an estimated $1.9 million each over their lifetimes through tourism, whereas a single dead shark fetches only $108 at market. The same economic principle applies to South Africa’s waters, where a live shark supports local businesses, jobs, and conservation efforts through sustainable tourism. The question then becomes: why are some still advocating for the mass culling of these creatures when they’re worth exponentially more alive?
Sharks Are Not the Enemy
Despite their economic value, sharks face persistent threats in South Africa. Misguided fears about shark attacks fuel calls for lethal control measures like drumlines and shark nets; outdated and ecologically damaging practices that indiscriminately kill marine life, including endangered species.
Ironically, these same sharks drive South Africa’s multimillion-dollar dive tourism industry, proving that their survival is inextricably linked to the economy.
By protecting the predators of the Sardine Run, South Africa preserves an ecological spectacle while securing jobs in tourism, hospitality, and marine conservation. It’s ensuring that communities along the coast continue to benefit from this natural event for generations to come.
From Passive Observers to Active Conservationists
“In the end, we will conserve only what we love; we will love only what we understand; and we will understand only what we are taught.”
Baba Dioum’s quote perfectly encapsulates why the Sardine Run and shark conservation efforts are so vital.
“We will conserve only what we love.” Experiencing the Sardine Run first and seeing sharks glide effortlessly through bait balls and feeling the sheer energy of the ocean, creates an emotional connection that turns spectators into advocates. It’s hard not to love something so breathtakingly wild.
“We will love only what we understand.” Sharks have long been vilified, but when people see them in their natural role as apex predators, shaping marine ecosystems, their fear turns into fascination. The more we understand sharks, the more we appreciate their importance in maintaining ocean health.
“We will understand only what we are taught.” Ecotourism, like responsible Sardine Run expeditions, plays a huge role in education. Through firsthand encounters, expert guides, and conservation messaging, people learn that sharks are worth far more alive than dead. This, in turn, supports coastal economies, balancing marine ecosystems, and ensuring the future of this natural phenomenon.
Critics argue that the Sardine Run disrupts natural feeding patterns or stresses marine life due to increased human activity. However, scientific studies suggest that well-managed ecotourism can actually enhance conservation efforts. The presence of responsible tour operators discourages illegal fishing, promotes marine research, and generates funds for conservation initiatives.
Furthermore, ecotourism advocates education and awareness. Anyone who’s ever been lucky enough to experience the sardine run will tell you how incredible it is to witness the greatest shoal on Earth and often leave as passionate champions for ocean conservation. In an age where marine species are vanishing at alarming rates, the Sardine Run may be one of the few large-scale events that turn passive observers into active conservationists.
The Sardine Run is an opportunity to teach, inspire, and create lifelong ocean ambassadors. If we want to protect sharks and the marine environments they support, we need more people to experience, understand, and ultimately, fight for them.
My Sardine Run Experience (Still Seems Surreal!)
Experiencing the Sardine Run firsthand in Cintsa on South Africa’s Wild Coast was one of the most incredible events of my life. I swam alongside foraging dusky sharks in focused grace, watched hundreds of common dolphins expertly and intelligently herd sardines into bait balls, observed the honed precision of countless Cape gannets diving, and saw gentle but giant Bryde’s whales effortlessly slicing through the schools.
My friends who stayed longer even had the amazing opportunity to interact with humpback whales. Cintsa is a hidden gem for the Sardine Run, offering an untouched wilderness without the intense competition of other operators. The encounters I had weren’t just breathtaking, they reinforced why this natural event is invaluable for conservation and ecotourism.
I will be forever grateful to Go Dive Mossel Bay for their incredible passion for the ocean and the unforgettable experiences they’ve given me. Their expertise and dedication to marine conservation made my Sardine Run adventure in Cintsa extraordinary. Cintsa is truly a hidden gem for the Sardine Run, offering an intimate, untouched wilderness where the ocean comes alive without the crowds.
The Bottom Line: The Sardine Run is Vital for Conservation in South Africa
The real controversy isn’t whether the Sardine Run is good or bad for conservation. It’s why we aren’t doing more to protect the species that make it so extraordinary.
Instead of fearing sharks or debating their presence, we should be celebrating them as a cornerstone of South Africa’s ecotourism economy.
Every shark in the Sardine Run represents a long-term financial investment, one that benefits local communities far more than a fleeting profit from finning or culling.
So, the next time someone asks whether the Sardine Run is a threat, remind them of this: a dead shark is worth a few dollars, but a live shark fuels an entire industry. South Africa’s future… both ecological and economic… depends on making the right choice.
