Fish

Rockin'! - This is the rock goby (Gobius paganellus). 
Amidst the algae and rocky substrate it was meant to be invisible. I would say that its erect dorsal fins gave it away....

Look at those cute serrated teeth!

Left to dry - It is not the most pleasent of views, but it does not mean it cannot be coverted into something more.

Traditional method from Nazaré, the fish; mackerels in this case (Trachurus sp); are caught and left do dry in trays at the beach. Where they can be seen and bought. Without proper data, I can only hope that these fisheries are sustainable

Leap of faith - A trout (Salmo trutta) doing its best to overcome a waterfall.

Migratory fish species depend on this ability to return to their spawning locations.
"Along the way, you gotta have faith".

Shannon? - I hereby present you: the shanny (Lipophrys pholis). Its fish friends call it Shannon. XD

It is a common species of blenny around rock pools during low tide.

PS: Sorry to have invaded your aquatic privacy... 

Frenzy of feeding fish! - Mullets such as these (Chelon labrosus) feed on detritus on the water column.

So, open your mouths "boys", it is chowder time! Never miss a spec of floating debris that nobody knows where it came from....
