SeaLife launches new underwater housing for iPhone
SeaLife is introducing a new compact and lightweight underwater housing for Apple’s iPhone. The new SeaLife SportDiver housing will allow divers to take photos and video with their iPhone down to 130 feet or 40 meters. The SportDiver can encase iPhone 7, 7 Plus, 8, 8 Plus, X, Xr, Xs, Xs Max, 11, 11 Pro Max, and SE (2nd Gen) models.
The heavy-duty housing is constructed of Polycarbonate, stainless steel, aluminum and optical grade glass. And while the SportDiver housing is “heavy duty”, it is not heavy, weighing less than 1.5 pounds (641 grams), and is lightweight for travelling and offers almost neutral buoyancy in water depending on which iPhone model is used.
The SportDiver is easy to hold and use and offers a large shutter lever and rear control buttons for easy operation, even with dive gloves. Snorkelers and Divers can get more creative with their photos or video shot by using advanced camera settings. Adjust Zoom, Exposure (EV), Auto/Manual Focus, White Balance, Tint, Lens selection, RAW+JPEG mode, Live Photo and Background Blur (on available iPhone models).
The SportDiver housing includes the free SeaLife SportDiver camera app for iOS 12 and up and unlike other smartphone housing apps, there are no annoying in-app purchases or ads. You can easily switch between photo and video mode. The SportDiver App uses the iPhone camera technology native to each iPhone® model.
The App Playback mode shows full size photos and videos with vertical thumbnail strip to easily locate your images. Videos start playing automatically when selected. All files are also saved to iPhone camera roll. The SportDiver housing automatically connects to your iPhone and the SportDiver app using Bluetooth® Low Energy (LE) 5 wireless technology. No cables or buttons touch the phone and offers ultra-low power consumption for both the phone and the housing which is powered by two AAA batteries that last over 50 hours of continuous use.
For enhanced imaging results, a removable underwater color-correction filter is included with the SportDiver which restores natural underwater colors. The filter easily attached or removes underwater and includes a safety tether to prevent loss. The SportDiver housing features triple 1/4-20 tripod mounts which mounts to any light or light tray with standard tripod threads such as SeaLife’s own range of Sea Dragon underwater photo/video lights. SeaLife also offers the SportDiver and Sea Dragon underwater light combined dubbed the “SportDiver Pro 2500 Set”.
For the phone’s safety and protection, the SportDiver has a sturdy holding spring and rubber grip tabs that securely hold the iPhone® in place and add shock-protection. The SportDiver has “Dual Leak Alarms” which include an internal moisture alarm and a vacuum pressure alarm which alert the diver with on-screen warnings, audio and LED signal in the unlikely event the waterproof seal is compromised and there’s a loss of housing pressure or moisture is detected. The door of the SportDiver is sealed with a TPE O-ring and a robust cam-lock sealing latch that easily and securely locks waterproof door. To prevent interior fogging from residual moisture, the SportDiver uses the anti-fogging agent “Moisture Muncher” capsule which prevents fogging and internal condensation.
Deliveries of the SportDiver iPhone housing are planned to start in November, 2020.

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.
