Primary classrooms throughout Ireland are celebrating cephalopods throughout the month of October with the launch of the Explorers Education Programme’s new educational resources focusing on squid.

Marine scientists around the world have been studying squid for many years, learning about their evolution, what they eat and what eats them, as well as their habitats and distribution in the global ocean,” says the Marine Institute’s Patricia Orme.

“When talking about cephalopods, we often think of the charismatic octopus, or the cuttlefish and their ability to change colours. However, squid also have special qualities, including the ability to see long distances in the dark, and being able to fly above the water.”

Squid have also been a point of interest for storytellers, artists, film-makers and museum curators the world over, says Cushla Dromgool-Regan of the Camden Education Trust.

“Led by the work of scientists, researchers and storytellers, the Explorers team are delighted to have produced a series of resources that will inspire teachers and children to learn more about the ocean, and possibly become ocean explorers themselves,” she adds.

Lineages among oceanic squids which have been said to puzzle researchers for over a century have been resolved by scientists at NUI Galway (NUIG).

A team at the NUIG Ryan Institute has been able to name the different family groups and says this provides important clues as to how squid evolved.

The findings have been published in the Zoological Journal of the Linnean Society.

Lead study author Dr Fernando Angel Fernández-Álvarez at NUIG's School of Natural Sciences spent five years collecting tissue from squid during oceanic cruises and when sampling from commercial trawlers.

“The aim was to solve the relationships among this amazing group of animals. I believe this study is an important milestone for the field and a good starting point for performing in-depth studies on the evolutionary trends that shape the huge diversity of oceanic squids,” he said.

“Our research could also be useful as we try to understand how our oceans will respond to ever-increasing pressures from human activities,” he added.

The research team used a method known as genome skimming to reveal the full sequence of DNA and identify relationships among squid.

Each of the discovered groups was named based on the rules dictated by the International Code of Zoological Nomenclature, the team says.

It suggests that scientists will have a way to accurately identify and describe the biodiversity of these marine creatures in the future.

Oceanic squids are a highly significant part of the marine food web.

They are voracious predators and provide the main meal of toothed whales and other endangered megafauna.

They include the largest group of commercially fished cephalopods, the flying squids.

The researchers also discovered what they say are "unexpected and as yet, unexplained, relationships".

"For instance, delicate deep-sea glass squids are more closely related to powerful muscular Humboldt squids and to the unusual monogamous diamondback squid, than to other oceanic squids," the NUIG team states.

“How these remarkable changes in form came about is not yet understood," Prof Louise Allcock of NUIG's School of Natural Sciences, Ryan Institute, explained.

“Oceanic squids are an amazingly diverse group of cephalopods – molluscs with arms and tentacles like squid, octopus and cuttlefish - with fascinating adaptations to their watery environment," she said.

" For example, glass squids use their body cavity as a fluid-filled buoyancy chamber, while chiroteuthids develop fishing lures at the end of their tentacles," she said.

“This study also highlights the importance of public scientific collections in addressing long-standing scientific issues," Prof Allcock added.

"We supplemented the material we collected ourselves with samples from various museums including the Smithsonian Institution in the USA, the Biological Reference Collection of the Marine Science Institute in Spain and the Australian Museum, allowing us to have a truly comprehensive oversight of oceanic squids globally,“ she said.

The study was funded by the Irish Research Council through the Government of Ireland Postdoctoral Fellowship Awards.

Deep sea fishing is alive and well off the west coast of Ireland, and not only is it a hugely enjoyable sport - just one catch can be enough to feed the whole family.
That's what The Irish Times' Elizabeth Birdthistle discovered in the last of her series on catching your dinner in Ireland.
Birdthistle set out for the waters off Inis Boffin with John Brittain, who has been skippering his angling boat Bluewater for 20 years for the charter fishing season between April and October.
The boat takes up to 12 anglers who are more than eager to pay €70 a head to catch large cod, pollack and mackerel in abundance. Even novices are welcome, as the fee covers all rods, tackle and tuition.
Squid and octopus are also on the cards, as are some larger quarries such as sharks and ray - though these can only be fished in a tag-and-release programme. Smaller catches also get thrown back to propogate.
"The biggest shark caught here weighed 150lbs," writes Birdthistle,  "and, as with all sharks caught, Brittain must tread with caution to release the giant hook or else the shark returns to the deep with part of his hand.
"The tagged sharks have been caught as far away as the Grand Banks off Newfoundland and the Cape Verde islands.

Marine Protected Areas (MPAs) - FAQS

Marine protected areas (MPAs) are geographically defined maritime areas where human activities are managed to protect important natural or cultural resources. In addition to conserving marine species and habitats, MPAs can support maritime economic activity and reduce the effects of climate change and ocean acidification.

MPAs can be found across a range of marine habitats, from the open ocean to coastal areas, intertidal zones, bays and estuaries. Marine protected areas are defined areas where human activities are managed to protect important natural or cultural resources.

The world's first MPA is said to have been the Fort Jefferson National Monument in Florida, North America, which covered 18,850 hectares of sea and 35 hectares of coastal land. This location was designated in 1935, but the main drive for MPAs came much later. The current global movement can be traced to the first World Congress on National Parks in 1962, and initiation in 1976 of a process to deliver exclusive rights to sovereign states over waters up to 200 nautical miles out then began to provide new focus

The Rio ‘Earth Summit’ on climate change in 1992 saw a global MPA area target of 10% by the 2010 deadline. When this was not met, an “Aichi target 11” was set requiring 10% coverage by 2020. There has been repeated efforts since then to tighten up MPA requirements.

Marae Moana is a multiple-use marine protected area created on July 13th 2017 by the government of the Cook islands in the south Pacific, north- east of New Zealand. The area extends across over 1.9 million square kilometres. However, In September 2019, Jacqueline Evans, a prominent marine biologist and Goldman environmental award winner who was openly critical of the government's plans for seabed mining, was replaced as director of the park by the Cook Islands prime minister’s office. The move attracted local media criticism, as Evans was responsible for developing the Marae Moana policy and the Marae Moana Act, She had worked on raising funding for the park, expanding policy and regulations and developing a plan that designates permitted areas for industrial activities.

Criteria for identifying and selecting MPAs depends on the overall objective or direction of the programme identified by the coastal state. For example, if the objective is to safeguard ecological habitats, the criteria will emphasise habitat diversity and the unique nature of the particular area.

Permanence of MPAs can vary internationally. Some are established under legislative action or under a different regulatory mechanism to exist permanently into the future. Others are intended to last only a few months or years.

Yes, Ireland has MPA cover in about 2.13 per cent of our waters. Although much of Ireland’s marine environment is regarded as in “generally good condition”, according to an expert group report for Government published in January 2021, it says that biodiversity loss and ecosystem degradation are of “wide concern due to increasing pressures such as overexploitation, habitat loss, pollution, and climate change”.

The Government has set a target of 30 per cent MPA coverage by 2030, and moves are already being made in that direction. However, environmentalists are dubious, pointing out that a previous target of ten per cent by 2020 was not met.

Conservation and sustainable management of the marine environment has been mandated by a number of international agreements and legal obligations, as an expert group report to government has pointed out. There are specific requirements for area-based protection in the EU Marine Strategy Framework Directive (MSFD), the OSPAR Convention, the UN Convention on Biological Diversity and the UN Sustainable Development Goals. 

Yes, the Marine Strategy Framework directive (2008/56/EC) required member states to put measures in place to achieve or maintain good environmental status in their waters by 2020. Under the directive a coherent and representative network of MPAs had to be created by 2016.

Ireland was about halfway up the EU table in designating protected areas under existing habitats and bird directives in a comparison published by the European Commission in 2009. However, the Fair Seas campaign, an environmental coalition formed in 2022, points out that Ireland is “lagging behind “ even our closest neighbours, such as Scotland which has 37 per cent. The Fair Seas campaign wants at least 10 per cent of Irish waters to be designated as “fully protected” by 2025, and “at least” 30 per cent by 2030.

Nearly a quarter of Britain’s territorial waters are covered by MPAs, set up to protect vital ecosystems and species. However, a conservation NGO, Oceana, said that analysis of fishing vessel tracking data published in The Guardian in October 2020 found that more than 97% of British MPAs created to safeguard ocean habitats, are being dredged and bottom trawled. 

There’s the rub. Currently, there is no definition of an MPA in Irish law, and environment protections under the Wildlife Acts only apply to the foreshore.

Current protection in marine areas beyond 12 nautical miles is limited to measures taken under the EU Birds and Habitats Directives or the OSPAR Convention. This means that habitats and species that are not listed in the EU Directives, but which may be locally, nationally or internationally important, cannot currently be afforded the necessary protection

Yes. In late March 2022, Minister for Housing Darragh O’Brien said that the Government had begun developing “stand-alone legislation” to enable identification, designation and management of MPAs to meet Ireland’s national and international commitments.

Yes. Environmental groups are not happy, as they have pointed out that legislation on marine planning took precedence over legislation on MPAs, due to the push to develop offshore renewable energy.

No, but some activities may be banned or restricted. Extraction is the main activity affected as in oil and gas activities; mining; dumping; and bottom trawling

The Government’s expert group report noted that MPA designations are likely to have the greatest influence on the “capture fisheries, marine tourism and aquaculture sectors”. It said research suggests that the net impacts on fisheries could ultimately be either positive or negative and will depend on the type of fishery involved and a wide array of other factors.

The same report noted that marine tourism and recreation sector can substantially benefit from MPA designation. However, it said that the “magnitude of the benefits” will depend to a large extent on the location of the MPA sites within the network and the management measures put in place.
