Scuba diving for marine biology

Marine biology and scuba diving go hand in hand.

Isobel is 13 year'sold, from Cardiff,  and already an accomplished scuba diver with over 30 logged UK dives including a night dive, sea dives and wreck dives. She has already seen loads of different marine life.

She learnt to dive because she wants to be a marine biologist.

WELSH DIVING is going to support Isobel  as one of our student apprenticeships to help her achieve her dream. You too can follow her diving adventures through her blog

Isobel will be documenting the wildlife she comes across on dives and discussing conservation techniques to the best of her ability.


July 2017

I completed a series of dives in Swanage, a small coastal town south east of Dorset.

Whilst diving under Swanage pier a peculiar creature caught my eye, which I later identified as the light bulb sea squirt. This peculiar little creature can be found attached to rocks, stones and seaweed all around the UK, however it can not be commonly found in many other places . it grows to just 2cm and stores its eggs and larvae in the atrial cavity. The eggs can be seen from outside because of the sea squirts clear body. Sea squirts inhale water along with the nutrients in that water so that they can digest any plankton. If disturbed they will exhale this water, hence the name ’sea squirt’.



A fair few of the fish on swanage pier had a type of sea lice attached to their heads, some of these lice had grown to around 2 inches long like the one shown below. The sea louse will attach to the fish and begin to feed off the blood, skin and mucus of the host. They then begin to grow whilst still attached.






If you’re looking at marine biology for your future studies and/or career, please get in touch so we can talk you through your scuba diving requirements and get you in the water!

Isobel recently qualified as a PADI Junior Advanced Open Water diver. She undertook a deep dive, learnt how to navigate underwater and perform effective search and recovery exercises. She also led a wreck dive and developed her buoyancy skills.

Isobel said:

Completing the advanced open water course helped me to enhance and build on my current diving knowledge. It also helped me to improve my confidence and open up new experiences within the sport.
