Here you can see nudibranchs found on the coast of Catalunya. Click on a photo and you can get a slideshow.

I agree that scuba diving is not a cheap hobby, especially if you want to invest in your own gear and dive exotic places. I would recommend doing the OW whenever possible, so as not to be limited. Although there is plenty of life to see at <12 meters over Posidonia meadows here on the Costa...

Are you interested in marine conservation? Are you a diver who would like to make a difference? You can support threatened marine habitats as a volunteer with the SILMAR Project. Discover the importance of key species like Posidonia oceanica and dive the magical Medes Islands marine reserve...

A lot of new divers join us as volunteers as it´s a cheap way to gain a lot of underwater experience. After a few weeks of mentoring whilst helping the project with data gathering their technique and air consumption improve no end. Before long they are enjoying hour long dives and not even...

I have been Eco Diving, researching Posidonia oceanica seagrass and other coastal species, with the help of volunteer divers since 2003. I became a voluntary coordinator with the SILMAR Project when it began in 2009, and offer international divers the opportunity to gain underwater conservation...

In Cala Montgó on the Costa Brava, where we have been diving and carrying out research with volunteer divers for the past 12 years, we have witnessed an estimated 25% loss of Posidonia oceanica seagrass beds, mainly as a result of unregulated anchoring by pleasure boats each summer. Where there...

Hey, thanks!

As part of European Shark Week (10 - 18 October 2009) Shark Alliance and its members such as us are targeting the government of Spain with a petition, which you can sign here: http://www.europeansharkweek.org Spain is a major exporter of shark fins to Asia and issues more special fishing...

I want to post the link to a petition for shark conservation but can't find the appropriate forum for this.

;)Do you have a favourite local dive site and a helpful buddy so that you can back into the water easily? You'll need help kitting up, but once you're under it'll be great!

I had to have a mastectomy in June 2007. I was devastated that my diving was to be interrupted mid research season especially when told that I wouldn't be able to dive for 18 months whilst undergoing treatment (chemotherapy & radiotherapy). Diving is my occupation as well as my passion and I...

Hi Lawrence Contrary to what has been said, the Mediterranean sea has a very rich biodiversity, with up to 12,000 recorded marine species, and new species still being discovered. The coastal zones supporting marine seagrasses like Posidonia oceanica are particularly productive as they are the...

Come and experience the wonderful diving in the Mediterranean. You'll be surprised to see the most beautiful corals and sponges, and marvel at the abundance and diversity of marine life. Based on the Costa Brava near the famous Medes Islands you can enjoy a week's stay with 10 dives...

I've finally identified the blenny as Parablennius marmoreus - Seaweed blenny, although a couple of the photos labeled as this blenny on Fishbase seem to be of Parablennius rouxi and Parablennius pilicornis golden variety. According to Fishbase it’s not supposed to be living in the...

Thanks Rick. The size and shape look about right and your link says that it appears in different colours. It doesn't mention the fin spot - which when you can see it is very distinctive. Also it's not supposed to be in the Med, although other species have migrated from the Red Sea. I'll...

This blenny has been found it in a couple of sites in 1 to 8 meters whilst carrying out fish surveys with Kennaecodiving in the Med. It is about 10 cm long with small paired tentacles over the eyes and lives in a hole in the rocks, popping out to feed. It is black apart from a spot on the...

Thanks. That one was all on it&#180;s own and I haven&#180;t seen anymore since. I do see cuttlefish in the same area but I don&#180;t know what a bobtail squid looks like. Does anyone have a photo of a bobtail squid? Are they nocturnal?

Can anyone identify the attached? It looks like an egg case and was found firmly attached to the Posidonia during last summer´s research in the Med. It measured about 1cm diameter by 1.5cm high. I can´t see my attachment, so I´ll put it in my gallery.

We are always looking for volunteers to help with our Posidonia research in the Med.

Thanks for the welcome folks. Yes, it was unusual to find a siphonophore inshore - a result of the traumuntana which was really severe last winter. Planning to dive this weekend with some guys coming over from the UK. Will keep you posted. Gaynor
