The Deep

mangrove swampThe Deep is a public aquarium in the city of Kingston-upon-Hull (often referred to simply as Hull) in East Yorkshire, and it’s a great place for a family day out.

The building was designed by world class architects, Sir Terry Farrell and Partners and opened in 2002. Perched right on the confluence of the River Hull and the Humber estuary, it still looks pretty modern today. It’s 5 minutes walk from Hull Marina and a short distance from the city centre.

Our visit to The Deep was on a rainy day last year and we’re very glad we went when we did, especially as we’d been considering going for some time. Unfortunately, like so many museums, parks and historic sites we like to visit, the aquarium has been closed since March this year due to Covid-19. We can only hope this wonderfully educational resource can survive financially to continue in the future.

Ocean knowledge

The journey through the aquarium begins with taking either the scenic lift or the stairs – eight flights of them – up to the third floor, where the main cafe (Castaways) is located. We chose the stairs (and my knees will  never forgive me). The ‘scenic lift’ is very very popular and queues to get in it were quite long when we were there.

The winding route down takes us through over 4 billion years of ocean history.

Looking down at the visitors The first display is The Awakening Earth, which comprises hands-on activities and 4D screens showing creatures that would have been swimming around in the oceans up to 400 million years ago. These included Dunkleosteus (370 m years ago) Ichthyosaur (240 m years ago) and Xiphactinus (80 m years ago).

There are also living starfish to see, a species which appeared on Earth around 450 m years ago. Starfish typically have five arms but some have up to forty! Those we saw all had only five:

This freshwater creature was also around almost 400 m years ago. It is called a tiktaalik and it grew to 3m in length, had sharp teeth and looked like a cross between a fish and a crocodile. It was, however, technically a fish and it lived on a continent called Laurentia, which was around the equator and had a warm climate.

The Lagoon of Light is a lovely display, being an open  stretch of  blue, tropical water filled with aquatic life found in a mangrove lagoon. Hundreds of colourful, tropical fish, rays and small sharks delight all visitors and are particularly popular with children.

There are information boards along the route, some specifically aimed at children, others for older visitors. They are all so useful and informative, like these about the importance of mangrove swamps:

There are also smaller tanks with living sea creatures of all types from specific environments of today, including Coral Reefs.

Lovely and colourful, and home to 25% of marine life on Earth, the variety of life on coral reefs is equal to that of the Amazon rainforest. It includes tiny plankton to predatory sharks  – all of which depend upon each other for survival. Worryingly, coral is very sensitive to environmental change, pollution and overfishing and the future of these fabulous reefs remains severely threatened.

The Kingdom of Ice is intended to give visitors a glimpse of  life in the polar realm and its importance to the ocean food chains, global warming, ocean acidification and so on.  The Gentoo penguins proved popular with adults and children alike and it was difficult to get close enough to the glass to take photos. We managed a few in the end.

There are so many different ocean environments as well as displays of some species in the Amazon Flooded Forest to visit. To show them all here would mean a very long post, so here are a few random photos, including a few information boards. There are tanks full of clown fish for all Nemo fans to enjoy, but the little fish must have been hiding in the anemones when we were there. Not surprisingly, another name for them is anemonefish. (The photo of the information board below is rather blurred, unfortunately.) At feeding times, the hiding clown fish readily emerge from amongst the stinging tentacles.

The main tank, called The Endless Ocean, fills the centre of the building, extending from the ground floor to the top, and can be viewed through large ‘windows’ on several levels, including an underwater viewing tunnel. The tank is filled with 550,000 imperial gallons of water (660,000 US) and 87 tons of salt. A variety of sharks can be seen, including White tip, Grey reef sharks and Zebra sharks, rays, and the only pair of Green sawfish in the UK. Turtles and rays swim past regularly, too. And although it wasn’t feeding time when we took these photos, we caught a glimpse of a diver in the tank, too.

The Endless Ocean can also be viewed from the Tunnel, which is 10 m below the surface. The tunnel is made is 6 inch thick acrylic and can take the weight of three elephants. It was very hard to take photos through, so the few we took aren’t very clear:

The Deep is a wonderful place for a day out, or for anyone on holiday in the East Yorkshire area. Children are fascinated by it and spend lots of time on the hands-on activities. There are cafes and picnic areas (some outside for when the weather is good). On rainy days the aquarium does get quite packed but it all adds to the fun. We had a great day there and learned a lot about the oceans and some of the hundreds of species that live in them.

The following quote from the ‘Welcome to Yorkshire’ website sums up the objectives of The Deep:

The Deep is an environmental and conservation charity, not run for profit, and is dedicated to increasing the knowledge and interest of the world’s oceans through its participation in vital research and conservation schemes around the world.
