The first 2013 dive: Pelagia noctiluca, Mallorca

This is an offshore species, but sometimes, like today, you can find them stranded in big numbers on beaches ... well, approximately 1 km off my beach. 

This species has got the ability to glow at the dark and nervous cells work to move tentacles and capture preys and furthermore to produce a toxin, biological poison.

It's got one cavity, digestive apparatus and guts in one cavity. Only one way in and one way out for feed food.

If you find yourself stuck with so many jellies, better off you are wet-suited.

A short clip.

What about pollution in Mallorca (and everywhere)

Mallorca is a magnificent island, although millions of tourists every year and sometimes the people from the isle itself forget to respect it and throw their rubbish away, no matter where and what damages that can cause. It is a really easy thing to do: throw your rubbish in bins. Of course the world is going to go on and on spinning around for many other thousands of years even with all the world polluted.

But people like me would love to continue looking at and living in a world full of floras and faunas life, not in mere polluted globe, drown in plastic everywhere.

Don't diss please, just respect it.

Today's dive in Majorca

Still wonderful Majorca nearby Can Pastilla, had I had my car I would go somewhere else huh...

Less tourist and more sea-animals, guess they are trying to get back and repopulate after such a summer full of people fishing for sport.

It was good to catch a shy and big octopus... tomorrow I'll annoy him/her a little more...

... and plenty of small jellyfishes, lucky me actually low-sea-temperature won't allow me to dive without wetsuit =)

Winter sea preview at Mallorca

Some general views in the winter sea at Mallorca by Cala Estancia. Freezing water to only dare diving by wetsuit. Super-duper clear water and above all no tourists!

The prehistoric shell!!! Huuuuuge!

How to repair your wetsuit

First off you need a strong glue, Neoprene Cement will do it.

1. Apply this glue to the inner parts of the scratches on your wet suit.

2. Wait 5 minutes to let it dry a little bit.

3. Apply again 'till you fill the scratch doing so. You can consider to sew it using dental floss to get a stronger  repair.

4. Let it all dry for an extra 20 to 50 minutes depending on the glue.

That's it! Just wait a couple of hours before swimming again.

In order to do all this, your wet suit need to be completely dry. 

Scorpionfish

Scorpaena scrofa

Most species of these are dwelling on the bottom and feed on crustaceans and smaller fishes.

General characteristics include a compressed body and ridges/spines on the head.

Spines all have venom glands at their bases.

Body adaptation during free-diving

When you dive you body will eventually adapt to the new more pressurized environment:

1 - A drop in the heart rate (...see reflex bradycardia)

2 - Your blood will have more red cells carrying oxygen (...see splenic contraction)

3 - Your blood vessels will shrink, leading away oxygen that benefits vital organs (...see vasoconstriction)

4 - Blood plasma will fill up blood vessels in the lungs and reduce residual volume. Without this adaptation, the human lung would shrink and wrap into its walls, causing permanent damage, at depths greater than 30 meters.
