11 Fascinating Facts About Seafood

Did you know that oysters have the ability to change their gender? Studies suggest that every oyster undergoes this transformation at least once in their lifetime.

Seafood encompasses a wide variety of species, shapes, and sizes. The term seafood refers to any sea creature that is considered fit for consumption.

It is surprising when someone claims that they do not like seafood because there is so much more to it than just a fish or a few oysters.

If you are not familiar with the different types of seafood, fret not. We have compiled some interesting facts about seafood to enlighten you.

Seafood is packed with essential nutrients!

Although the amounts of various vital nutrients differ among different seafood species, it is safe to say that seafood is a great addition to any diet.

Salmon, for instance, is rich in vitamin A and omega-3 fatty acids. Other nutrients that are found in seafood in healthy quantities include vitamin D, vitamin B1, vitamin B3, vitamin B12, and more!

Humans have been consuming fish for over 165,000 years!

During the early years, humans were primarily hunter-gatherers who were always on the move in search of better hunting grounds or more abundant crops.

Seafood was one of the foods that our ancestors consumed regularly. It is possible that the first instances of humans adopting a more sedentary lifestyle occurred in tribes that lived by the sea and had a steady supply of seafood.

The earliest evidence of seafood consumption dates back to 165,000 years ago and was found in a sea cave in South Africa where collections of empty shells were discovered.

The mantis shrimp is one of the most terrifying shellfish.

We are fortunate that the mantis shrimp is not capable of growing to large sizes because if it were, it would be downright frightening.

Why, you ask? The mantis shrimp has a punch so powerful that it can generate the same force as a rifle shot. Its punch is so strong that it creates a shockwave that can dismember its prey and boil the water around it.

Fatty fish such as salmon, mackerel, and sardines are abundant in omega-3.

If you are not familiar with omega-3, it is an essential nutrient that is beneficial to your body.

While all fats were once considered unhealthy, some, such as omega-3, are actually good for you. Eating seafood rich in omega-3 can help reduce the risk of heart attacks, strokes, and alleviate arthritis symptoms.

Studies have also shown that omega-3 consumption can prevent age-related vision loss and improve night vision.

Shrimp and prawns are not the same.

Many of us have experienced confusion between shrimp and prawns. Although both are crustaceans and have 10 legs, they differ in many ways. Shrimp can survive in both fresh and saltwater, while prawns can only live in freshwater. Prawns are usually larger and have three sets of claws, unlike shrimp, which only have two. It’s essential to note that there’s no such thing as certified organic seafood. There are no governing bodies that regulate the seafood industry to ensure that everything is chemical-free and up to standard. Lobsters have two claws, and they serve different purposes. The larger of the two is the crusher claw, which is primarily used for crushing hard shells or exoskeletons. The other claw is smaller and more serrated, used to tear the prey’s flesh to shreds. Some fish, such as King mackerel, swordfish, and sharks, contain high levels of mercury and should be eaten in moderation. Seafood isn’t limited to animals; it can also include sea vegetation. Oysters are born male but have both male and female reproductive organs and can fertilize their eggs without the need for another oyster.

Research has shown that every oyster undergoes a gender transformation at least once during its lifetime.

Overfishing has affected more than 85% of the world’s fisheries.

The United Nations Food and Agriculture Organization warns that urgent action is needed to change the way we farm and consume seafood, as 87% of the world’s fisheries are under significant stress.

This puts certain species at risk of extinction, causes a dramatic decrease in their population, or leads to overexploitation.

Although some people dislike seafood, it remains a popular choice for many, and its demand is increasing every year.

As the world’s population grows, the issue of overfishing becomes more pressing, and unsustainable levels of seafood consumption threaten its availability in the future.

It’s important to realize that, if we’re not careful, we may face a decline in seafood supply over the coming years, despite its delicious taste.
