Every year The Deep welcomes a small number of students behind the scenes, allowing them to undertake crucial research for their end of year thesis, focusing on the marine environment.

By looking into topics such as behaviour, reproduction, feeding and habitats - to name a few - they are not only working to complete their studies, but their findings can play a crucial role in the continual development of species management within aquariums.

Many of our students come form Hull University and are studying for either their Bachelors or Masters Degree in Marine Biology, Zoology or similar subjects. These studies have allowed them to progress onto complete a PhD in their chosen topic or provided them with the knowledge and experience needed to undertake conservation work out in the field and across the globe. 

Choon (pictured) is one of our 2018 students. She is currently in her 3rd year at Hull Univeristy where she is completing a her degree in Zoology. Choon is researching our  Blue Spotted Ribbontail Rays and the Blue Spot Rays within the Lagoon of Light. By examining the behavioural interactions between the two species during feed times, such as food competition, she hopes to establish if there is a dominance hierarchy present between the two separate species alongside the hierarchy that is already evident between individuals of the same species. Similar interactions between the rays and Zebra sharks will also be explored.

Other topics being researched this year include: Sophie is invesitgating behaviour and communication in Gentoo penguins; Matt is measuring the production of planular larvae in corals in repsonse to the type of food consumed and the light they are exposed to, to identify the best conditions for optimal reproduction within aquariums and Jessica is working to develop a Health Index for Corals. Jessica is comparing two seperate species of corals, using their photosynthetic activity and polyp extension as a measure of health in response to various factors such as food, salinity, light and air exposure.

You may see them around the aquarium with a dashing blue clip board or armed with a go-pro camera. We wish them the best of luck with their studies and the final production of their research dissertation later in the year.

Our used cooking oil from the cafe and Two Rivers Restaurant is collected and recycled! EYB Oil Solutions is a Hull based business specialising in turning oils and fats into clean energy. 

After collecting the oil it is taken to a processing plant where it goes through a filtration process, allowing it to be used for a variety of energy needs. Most of the oil is turned into biofuel for vehicles, with the rest being sold to the grid for residential energy. Gav has a great passion for his local area and the environment and we think he is a star! You can learn more about his business on his website

Did you know?

• More than 3,000 homes are flooded in the UK each year because of fat, oil and grease blockages
• £90 million is spent every year on clearing fat, oil and grease blockages across the country – money that could be passed to you in savings
• As well as causing blockages leading to flooding, build-ups of fat, oil and grease can also put waste water pumping stations out of action

• The Deep uses rapeseed oil provided by AAK Oil.  Rapeseed oil has a high smoke point meaning it lasts longer than other types of oil. It is also low in saturated fats, contains lots of vitamin E and is grown locally!

The Deep is delighted to welcome a stunning photographic gallery of marine creatures from underwater photographer Nuno Vasco Rodrigues. His gallery demonstrates life, large and small, and captures the beauty and fragility of the underwater world.

Nuno works as the Assistant Curator at Oceanário de Lisboa and as a researcher at MARE-IPLeiria in Portugal. He has a special interest on fish ecology and uses his images as a tool for research, conservation and education, and as such, has published a variety of scientific papers on the life he has studied.

He is the author of the book Marine Fishes of Portugal and co-author of two books about marine fauna, one of which is currently being finalised (Marine Fishes of São Tomé & Principe, Africa). His photos have been published in exhibitions, newspapers, magazines and both national and international books. Nuno has been passionate about the ocean and its inhabitants from a very young age, he became SCUBA certified in 2000 and hasn’t stopped diving since.

Nuno’s work has only once been seen in the UK once as part of the 2017 Manchester Science Festival, but has not featured as part of a longstanding exhibit. 

Katy Duke, CEO at The Deep is thrilled to give Nuno the opportunity to display his images here at The Deep. Having worked together for many years through The Deeps partnership with Oceanário de Lisboa, she feels it is afantastic chance not only to be able to showcase a diversity of species but also the important relationships aquariums across the world forge. We are all working together to protect our world’s oceans, so exhibiting Nuno’s stunning images is a wonderful way to celebrate this.

Nuno Vasco Rodrigues has praised The Deep for the work it is doing and commented on how he feels it is a great honour to have the opportunity to display my work at such a renowned organisation that is actively engaged in marine conservation and education. Hull´s maritime history, makes The Deep a great location to engage audiences with the marine environment.

The gallery is free to view and can be found on the third floor of The Deep. Nuno’s images will be on display from Friday 2 February 2018 until the end of January 2019.

The annual animal census is underway at The Deep, from the tiny Leaf cutter ants to the enormous Green sawfish, every animal needs to be counted and accounted for. 

With over 5,000 animals representing over 300 different species, The Deeps’ Aquarists have a huge task on their hands to accurately record each individual animal within the aquarium. Armed with just a clicker and a clipboard, the swift colourful flash of a moving reef fish really drives home the difficulty of this job. With many constantly on the move, a lot of patience is needed and at times, a lot of re-counts!

Curator, Ben Jones tells us more: “With many of our animals on the move all the time the annual census can take a number of days to complete. With so many to count, the species are usually divided up between the Aquarists so it really is a team effort to complete.

Our animal records are completed on a daily basis, but each year a compulsory review of all our populations is required to comply with our Zoo License. This activity simply confirms our species numbers as we enter the New Year”.

2017 welcomed a number of new residents into this past year’s census, including the two Loggerhead Sea Turtles who arrived back in the spring of 2017, as well as a whole host of reef fish species following the refurbishment of the Lagoon of Light exhibition. Successful breeding of the David Bowie spider and the culturing of a number of jellyfish species, all will add to the upcoming final figure.

Amongst those being counted, some are threatened with extinction. This count is not only important for confirming numbers, but is shared with other zoos and aquariums across the globe, providing essential data for planning breeding programmes for these vulnerable and engendered creatures.

The Deep welcomes two brand new jellyfish species and celebrates a UK first! Visitors can now see both the majestic Pacific sea nettle and the stunning Mediterranean jellyfish in the Cool Seas zone.

After welcoming some polyps of the Mediterranean jellyfish from L'Oceanografic in Valencia, Spain, our specialist jellyfish Aquarists have managed to culture this species for the first time in the UK.

Each polyp releases tiny jellyfish called ephyra, each only 1-2mm across, initiating the delicate task of raising them into adulthood. Sometimes known as an 'egg jellyfish' the centre of their body becomes coloured with the food they have eaten. They can be found in the waters of the Mediterranean Sea and its coastal lagoon and can grow up to 35cm in diameter. Despite their size, they have a mild sting, so beachgoers need not to worry about them as much. They have a near translucent body and clusters of colourful oral arms underneath. These blue-purple appendages are essentially the jellyfish's mouth parts, where they can digest the plankton on which they feed.

Jellyfish are closely related to corals and one trait of the Mediterranean jellyfish really highlights this - it glows! Like corals, the frilly oral arms of this jellyfish contain plant-like algae called zooxanthellae, allowing it to generate its own food from the sun through photosynthesis. This algae contains fluorescent pigments, protecting the zooxanthellae from the harmful rays of the sun.

Aquarist Shoshana says; "We are so excited to be able to share these beautiful jellies with our visitors. Rearing a new species of jellyfish always presents a challenge, some jellyfish can be are very sensitive in the early stages so getting them through the difficult period really creates a sense of achievement. They are a fast growing species, so once we get them to the size of a 10p coin the pressure is lessoned slightly. We have a number of different life stages growing behind the scenes so we hope to have them on display for a while. We now have four very different species on display, so it’s great to be able to show off the diversity of shapes, sizes and colours within the jellyfish family".

Also joining the jellyfish exhibits this week are the Pacific sea nettle. Reaching up to 45cm in diameter, they trailing their long stinging tentacles behind them as they drift through the water. These stinging tentacles pack a punch and are capable of paralyzing even small fish and other jellyfish for them to eat.
