If you’re a seafood lover—or just curious about what goes on behind the scenes—read on for 10 incredible seafood facts that will truly blow your mind.
1. The Deepest Fish on Record Lives Over 27,000 Feet Below the Surface
Did you know that the deepest fish ever recorded was discovered at a staggering 27,000 feet below the ocean’s surface? The Macrourid (a type of deep-sea fish) can withstand immense pressure in the dark, icy depths of the ocean. These resilient fish are far beyond what most of us think of when we imagine the average fish swimming in the sea.
2. Some Fish Can Change Gender
A surprising number of fish species can change their sex in response to environmental factors. For example, Clownfish (yes, the same ones made famous by Finding Nemo) are born male, but if the female of their group dies, the largest male will transform into a female to ensure reproduction continues. This natural phenomenon helps ensure the survival of the species.
3. Seafood Has More Omega-3s Than Most Other Foods
If you’re looking for a heart-healthy, brain-boosting food, seafood is a powerhouse. Salmon, mackerel, and sardines are especially rich in omega-3 fatty acids, which are essential for reducing inflammation and supporting brain health. In fact, seafood has been shown to provide more omega-3s than any other food group.
4. Oysters Can Change Their Sex Multiple Times
Not only do some fish change sex, but oysters are also capable of altering their gender multiple times throughout their lives. They start off as males, and later in life, they can switch to females. This unique trait makes them incredibly versatile in their reproductive capabilities.
5. The World’s Most Expensive Fish Can Cost Over $3 Million
When it comes to extravagant seafood, the bluefin tuna takes the prize. One particular tuna caught in Japan in 2019 sold for an astounding $3.1 million. While this is an extreme case, it underscores the rarity and demand for high-quality seafood in global markets, particularly in sushi restaurants.
6. Shrimp Are the Most Consumed Seafood in the World
Among all seafood types, shrimp reigns supreme as the most consumed. Over 4 million metric tons of shrimp are harvested globally each year. Whether served in cocktails, pasta, or stir-fries, shrimp has become a universal favorite across cultures.
7. Lobsters Were Once Considered “Poor Man’s Food”
In the 17th and 18th centuries, lobsters were so plentiful that they were primarily used as fertilizer and fed to prisoners, servants, and children. It wasn’t until the late 19th century that lobsters became a luxury seafood item, as their supply dwindled and demand increased.
8. Some Fish Have Built-In Sunscreen
Many fish living in shallow waters have evolved the ability to protect themselves from the sun’s harmful rays. Parrotfish, for example, secrete a mucus cocoon around themselves at night, which acts as a barrier against UV rays and parasites. This natural sunscreen keeps them safe as they swim through the sunlit waters.
9. There Are Over 3,000 Types of Edible Fish
Did you know that there are over 3,000 different species of edible fish? While salmon, tuna, and cod may be the most common, the diversity of fish available around the world is astounding. From the exotic tilapia to the elusive halibut, each species offers unique flavors and textures for culinary exploration.
10. Seaweed is a Superfood for Seafood Lovers
You might not think about seaweed as part of the seafood family, but it is often consumed alongside seafood dishes for both flavor and nutrition. Seaweed is packed with vitamins, minerals, and fiber, and is often paired with fish in sushi rolls or added to broths. It’s a natural, sustainable food source that has been used for centuries in coastal cuisines.
Conclusion: Seafood is Full of Surprises
