Must-watch marine conservation movies
We live in a time where the conservation of our oceans & seas has become critical. We must act now, but sometimes it can be difficult to know where to start, or how to inspire people to change. Over-fishing, climate change, animal abuse, pollution, habitat destruction and complacency are all contributing to the death of marine life. Fortunately, we also live in a time where information can be shared quickly all around the world. We live in an age where very talented and brave (sometimes risking attack or imprisonment) marine conservation activists can make a film and get it seen by millions, in the hope that it will change our attitudes and behaviours.
Here is our list of MUST-SEE films on marine conservation. Some are not easy to watch. Some will leave you in tears. They are all excellent. Let us know if we have missed any that you think we should watch and add to the list!
Blackfish
Blackfish tells the story of Tilikum, a performing killer whale that killed several people while in captivity. Along the way, director-producer Gabriela Cowperthwaite compiles shocking footage and emotional interviews to explore the creature’s extraordinary nature, the species’ cruel treatment in captivity, the lives and losses of the trainers and the pressures brought to bear by the multi-billion dollar sea-park industry. Blackfish is a film that has had a huge global impact.

The End of the Line
Imagine an ocean without fish. Imagine your meals without seafood. Imagine the global consequences. This is the future if we do not stop, think and act.
Directed by Rupert Murray, The End Of The Line is the world’s first major documentary about the devastating effect of overfishing and examines the imminent extinction of bluefin tuna, brought on by increasing western demand for sushi; the impact on marine life resulting in huge overpopulation of jellyfish; and the profound implications of a future world with no fish that would bring certain mass starvation.
Filmed over two years, The End of the Line follows the investigative reporter Charles Clover as he confronts politicians and celebrity restaurateurs, who exhibit little regard for the damage they are doing to the oceans.

The Last Ocean
The Ross Sea, Antarctica is the most pristine stretch of ocean on Earth. A vast, frozen landscape that teems with life – whales, seals and penguins carving out a place on the very edge of existence. But an international fishing fleet has recently found its way to the Ross Sea. It is targeting Antarctic toothfish, sold as Chilean sea bass in up-market restaurants around the world. The catch is so lucrative it is known as white gold. Ecologist David Ainley knows that unless fishing is stopped the natural balance of the Ross Sea will be lost forever.

A Plastic Ocean
Plastic Oceans has assembled a team of the world’s top scientists and leading film makers to produce a powerful, high-end documentary in high definition ‘A Plastic Ocean’. This will play a key role in sending out the message to the world. Accompanied by scientists, conservationists and engineers, the film follows the journey of two explorers as they travel to some of the most remote parts of the world, documenting the environmental issues associated with plastic pollution and its impact on the environment, ecosystems and human health.

Creature Feature: Undulate Ray
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.
This month we’re looking at the Undulate Ray. Easily identified by its beautiful, ornate pattern, the Undulate Ray gets its name from the undulating patterns of lines and spots on its dorsal side.
This skate is usually found on sandy or muddy sea floors, down to about 200 m deep, although it is more commonly found shallower. They can grow up to 90 cm total length. Depending on the size of the individual, their diet can range from shrimps to crabs.
Although sometimes called the Undulate Ray, this is actually a species of skate, meaning that, as all true skates do, they lay eggs. The eggs are contained in keratin eggcases – the same material that our hair and nails are made up of! These eggcases are also commonly called mermaid’s purses and can be found washed up on beaches all around the UK. If you find one, be sure to take a picture and upload your find to the Great Eggcase Hunt – the Shark Trust’s flagship citizen science project.
It is worth noting that on the south coasts, these eggcases can be confused with those of the Spotted Ray, especially as they look very similar and the ranges overlap, so we sometimes informally refer to them as ‘Spundulates’.
Scientific Name: Raja undulata
Family: Rajidae
Maximum Size: 90cm (total length)
Diet: shrimps and crabs
Distribution: found around the eastern Atlantic and in the Mediterranean Sea.
Habitat: shelf waters down to 200m deep.
Conservation Status : As a commercially exploited species, the Undulate Ray is a recovering species in some areas. The good thing is that they have some of the most comprehensive management measures of almost any elasmobranch species, with both minimum and maximum landing sizes as well as a closed season. Additionally, targeting is entirely prohibited in some areas. They are also often caught as bycatch in various fisheries – in some areas they can be landed whilst in others they must be discarded.
IUCN Red List Status: Endangered

Guarding Against Coral Invaders
Protecting (Dutch) Caribbean Reefs from Unomia stolonifera
Recent reports highlight the concerning spread of the invasive soft coral, Unomia stolonifera, currently devastating Venezuela’s marine ecosystems and detected in Cuba. With the potential threat of its expansion to the (Dutch) Caribbean islands, urgent action and awareness are essential to safeguard marine biodiversity and local economies from possible catastrophic consequences.
Invasive species are animals or plants from another region of the world that don’t belong in their new environment. These species can have major ecological effects by decimating native flora or fauna. They can also cause large economic losses and impact human health. Invasive species also pose a significant threat to marine ecosystems worldwide, including the Dutch Caribbean. Among these invaders is the octocoral species Unomia stolonifera or “Pulsing Xenia”, originally from the Indo-Pacific. With its rapid growth and lack of natural predators, this species can outcompete native species and disrupt fragile marine habitats such as seagrass beds and coral reefs.
Background
The invasive soft coral U. stolonifera was first identified in 2014, off the coast of Venezuela. It is believed to have been introduced via the illegal aquarium trade. Since this species can reproduce sexually and asexually (or fragment), even small pieces can regenerate to spread. Once introduced it quickly took over shallow reefs and hard substrate at depths of 0-50 meters, outcompeting local corals and seagrass for space. Follow on surveys found that this coral species exhibited average percentage cover as high as 80%, vastly outcompeting native corals. In highly colonized areas, fish are disappearing due to loss of habitats.
In 2022, during a survey conducted in Cuba by the University of Havana, an unknown octocoral was discovered which was later identified as the invasive Unomia stolonifera. It is suspected that the coral larvae arrived in ballast water from fossil fuel ships originating from Venezuela, as nearby sites adjacent to Venezuelan ports have been heavily affected by the invasion.
How to help
Prevention through continuous monitoring, particularly in high-risk areas such as marine harbors and oil facilities, is paramount. Early detection plays a pivotal role in mitigating the threat posed by Unomia stolonifera.
The public’s involvement and awareness are also vital. Local communities, recreational divers, tourists, and all stakeholders are urged to participate in early detection efforts by reporting sightings (photo, location and date) of this invasive coral to their respective Protected Area Management Organization (PMO’s)- the Fundacion Parke Nacional Aruba (FPNA), STINAPA Bonaire, CARMABI Curaçao , Saba Conservation Foundation (SCF), Nature Foundation St. Maarten (NFSXM) and St. Eustatius National Parks (STENAPA). If an invaded area is confirmed, follow the recommendations by the local PMO’s.
Keys to Success
Despite the challenges, early detection is key to mitigating the threat posed by Unomia stolonifera. With continued vigilance, research, and community engagement, there is hope for containing this potential issue before it becomes a major threat.
