New series: Intro to REEFS GO LIVE with The Central Caribbean Marine Institute – CCMI (Watch Video)

Published

on

Introduced by Jeff Goodman…

Exploring a coral reef is beyond the experience and possibly dreams of many people, especially younger ones. Seeing and knowing the incredible diversity and complexity of marine life is exciting and enlightening in both vocational and educational ways.

With today’s incredible advances in communication technology, we are now able to communicate ‘live’ with divers underwater from anywhere in the world. The Central Caribbean Marine Institute – CCMI are doing just that!

As our reefs and greater oceans are being stripped of wildlife, it is important that we learn more about these unique habitats and species before they are beyond saving. With CCMI, students are able to talk with marine scientists diving on a coral reef, in real time from anywhere in the word.

Baba Dioum, a Senegalese forestry engineer born in 1937, famously once said: “In the end, we will conserve only what we love; we will love only what we understand and we will understand only what we are taught.”

Covid -19 is affecting us all and as a result CCMI have told me that at present, they cannot confirm when they will be running more live broadcasts but all the previously run broadcasts are available.

Let me introduce you to CCMI ‘Reefs Go Live’ and over the coming weeks, Scubaverse will be a showing a selection of past programme videos and keeping you up to date for future events.

REEFS GO LIVE

As terrestrial beings, most people are challenged to understand the unique processes of the ocean or even fathom being able to take the plunge and dive below the waves. Among the challenges is that urban, rural and geographically land-locked people perceive the ocean to be a distant place beyond their reach. In addition, scientists are often conducting research on relevant topics at remote locations where it is virtually impossible for the majority of the general public to gain a first-hand experience. This reality creates enormous financial, logistical, physical constraints on bringing people into the field where they can directly explore the ocean.

CCMI’s education team has developed a transformational, interactive education programme using Virtual Live Experiences (VLEs) methods to connect students and the public to real-time coral reef activity, in an informal science setting. Scientists use high tech face masks and streaming computer equipment to deliver live lessons from the underwater and lab environment. Innovative technology enables VLEs to reduce barriers to learning by communicating interactive ‘real-life’ experiences in an informal, scalable science setting.

The project is structured to deliver curriculum-relevant lessons which are currently oriented to the Cayman Islands and UK national science curriculum for students in year 5 and year 6 classrooms, and which can be streamed directly anywhere in the world. This groundbreaking work was piloted in local schools initially and has the potential to become an international project, as students have tuned in from Bermuda, the UK, Peru and the United States.


Do you want your students to be a part of this adventure below the waves? Contact CCMI here and look for the Reefs Go Live videos to be posted here and on CCMI’s YouTube channel.

Creature Feature: Undulate Ray

Published

on

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 BonaireCARMABI 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.
