8 Critically Endangered Marine Animals

Have you ever wondered about the incredible life beneath the ocean’s surface? We often marvel at the vast, mysterious world of marine life, from the playful dolphins to the majestic whales. But did you know that many marine animals are hanging by a thread? Yes, even the ones we love to watch on documentaries or dream of seeing on a snorkeling trip.

World Ocean Day on June 8th brings attention to this urgent issue. Our oceans, which cover over 70% of the Earth's surface and are home to possibly a million species, are in jeopardy. But what’s driving these species to the brink? How can you, sitting at home, make a difference? Stick around, because by the end of this post, you’ll know and hopefully be inspired to take action! Let's dive in knowing the Endangered Marine Animals on Earth!!

Oceans are our planet's lungs. They produce more than half of the world’s oxygen. They absorb up to 90% of the heat generated by greenhouse gases. But our relentless activities are putting these magnificent ecosystems under severe stress.

Climate Change: Oceans absorb heat, which affects marine life and causes coral bleaching. The critters that call coral reefs home suffer the most.

Pollution: Imagine dumping at least eight million tonnes of plastic into the ocean every year. Scary, right? Add to that harmful chemicals and human waste.

Overfishing and Bottom Trawling: These practices are decimating marine populations and ripping apart ecosystems.

Ever seen a shark with a head that looks like a hammer? That's the Great Hammerhead Shark. It’s the largest of its kind, reaching up to 6.1 meters (20 feet) and weighing around 450 kg (about 992 pounds). They thrive in warm coastal waters around the globe and can live up to 20-30 years. But here's the catch— they reproduce only every two years.

Threats: These magnificent creatures are targeted for their fins, which is a sad consequence of the lucrative shark fin soup trade. They also end up as bycatch in fishing nets. As a result, the IUCN (International Union for Conservation of Nature) lists them as critically endangered.

With a snake-like body that can reach up to 1.3 meters (about 4.3 feet) and weigh around 6.5 kg (14 pounds), the European Eel is a fascinating creature. Born in the Sargasso Sea, these eels migrate all the way to European rivers. They return to the Sargasso to spawn and die—a journey so epic it could be the plot of a blockbuster.

Threats: Migration barriers like dams and turbines, combined with overfishing, have driven their population to a crisis point. The European eel is alarmingly scarce.

Imagine a sea star with 16-24 limbs, each stretching up to one meter (about 3.3 feet). These are the Sunflower Sea Stars. They used to be abundant along the Pacific coastline of North America.

Threats: Over the past 30 years, their population has declined by 90%, primarily due to a mysterious wasting syndrome possibly linked to rising water temperatures. Scientists observe no natural recovery.

Looking more like a pancake than a shark, the Angelshark is a flat, nocturnal bottom-dweller that can grow up to 2.5 meters (about 8.2 feet). They inhabit the Eastern Atlantic and Mediterranean Sea, living for around 15 years.

Threats: They fall victim to bycatch in bottom fishing gear. Imagine a species with an 80% population contraction in just a century! Shockingly, they’re now critically endangered.

Another hammerhead species, these sharks are non-aggressive and tend to be shy around divers. They prefer tropical to warm waters.

Threats: Like their great cousins, Scalloped Hammerheads are targeted for their meat and fins. Although populations in the northwest Atlantic and Gulf of Mexico have stabilized due to bans and treaties, the IUCN still classifies them as critically endangered.

These sharks, which can grow up to 3.5 meters (around 11.5 feet) and live up to 25 years, are constantly on the move to breathe. They inhabit tropical and subtropical waters worldwide.

Threats: They are highly sought after for their flesh and fins and are a mainstay in commercial fisheries. You can learn more about their critical status from the IUCN [here](https://www.iucnredlist.org/species/39374/2911619).

These whales are massive, reaching up to 16 meters (about 52 feet) and weighing around 70,000 kg (about 154,324 pounds). Unfortunately, there are fewer than 250 mature individuals left.

Threats: They are often entangled in fishing gear and struck by ships. This is a significant concern along the east coast of North America. The slow and cumbersome efforts to keep them safe make their future uncertain. Learn more on the IUCN site [here](https://www.iucnredlist.org/species/41712/105108669).

These warm-water reef fish are bicolor patterned and primarily inhabit the Caribbean Sea and Gulf of Mexico.

Threats: High commercial and recreational fishing pressure has slashed their population by 80-90% since the 1980s. They were classified as critically endangered in 2016 by the IUCN. Get more details [here](https://www.iucnredlist.org/species/7862/13498379).

You might be wondering, "Is there anything I can do to help these distant creatures?" Absolutely! Here are a few actionable steps:

Reduce Plastic Use

Ever thought about how much plastic you use daily? From water bottles to shopping bags—every little bit counts. Try to minimize your plastic usage. Opt for reusable bags, bottles, and straws. Every piece of non-used plastic is a victory for marine life.

Support Sustainable Seafood

When you buy seafood, are you sure it’s sustainably sourced? Check for labels like the Marine Stewardship Council (MSC) certification that ensures your seafood is sourced responsibly. Avoid species that are overfished or endangered.

Promote and Support Conservation Efforts

Donate to organizations like WWF, IUCN, or Ocean Conservancy. Your money can fund vital research and conservation programs that can make a real difference.

Participate in Beach Clean-ups

Join a local beach cleanup activity. It's a fun, community-driven way to keep our beaches and oceans clean. Plus, it’s highly rewarding to see immediate results.

Educate Yourself and Others

Keep yourself informed and spread the word. Social media is a powerful tool—use it! Share information, raise awareness, and inspire others to act.

Get Involved Legally

Support policies and laws that aim to protect marine environments. Advocacy can pressure governments to enforce stricter regulations on fishing practices, pollution, and marine conservation.

Our oceans are wonderlands teeming with life but facing unprecedented threats. The critically endangered marine animals we've discussed are a testament to this crisis. But it’s not all doom and gloom. By reading this blog post, you’re already taking the first step toward making a difference.

Remember, every small action counts. Whether it’s reducing plastic use, supporting sustainable seafood, contributing to conservation programs, or participating in local cleanup drives—all these efforts add up.

Let’s act now. Our planet’s future, and that of the amazing creatures within it, depends on us.

Feeling inspired? Great! Here’s what you can do next.

1. Reduce Your Plastic Footprint: Ditch single-use plastics. Go reusable.

2. Inform Yourself: Get smart about your seafood choices.

3. Donate to Conservation Efforts: Every dollar counts. Start with organizations like WWF or Ocean Conservancy.

4. Join a Beach Cleanup: It’s fun, effective, and creates instant positive impact.

5. Spread the Word: Use your voice. Share this blog. Educate others.

We have the power to change the fate of these critically endangered marine animals. Let's do it!
