Will you be a fan of the mysterious and fearsome sharks, a connoisseur of the colours, fantasy and variety of the tropical fishes like the Cowfish, the Rockmover Wrasse or the Clown Triggerfish; will you become an specialist in freshwater species such as Barbel or the Goby, or are one of those people who, in the end, always prefer the simple and shy starfish?
Maybe you just won’t be able to decide!

Who knows if you’re make up your mind here, at SEA LIFE Porto, after seeing so many animals, from the most curious to the most friendly, from the rarest to the most enigmatic, maybe you’ll be even more confused. But at the same time, far more knowledgeable and fan of the wonders of the marine world. And a firm advocate of the conservation of the Oceans!
Many of our residents are part, to our great sadness and concern, of the list of endangered species. Others were born right here, under our care and watchful eyes, like the Bamboo Sharks. Others still, have personality traits that are really worth a visit!


Starfish (on the right).
Starfish (on the right).

The starfish belongs to the phylum of echinoderms; they are cousins of sea urchins and inhabit all the oceans around the world. Most starfish have five limbs. But this is not the case for all: some species can have up to 50 well-developed arms and others have limbs so short as to seem pads. Starfish spend the day in search of food, and their favourite prey are sea urchins and mussels.

Starfish have the ability to open the shells of mussels due to the strength of their arms, and they evert their stomachs from their mouths so as to digest molluscs externally. Starfish have a significant regenerative capacity: if they lose a limb, in fact, they are able to grow another one just like it.


– Some species of starfish are bioluminescent.

– The diameters of starfish vary from 2cm to 1metre.

– Starfish arms contain many small suction cups, called ambulacral pedicels, that make it possible for the starfish to move on the substrate.Some species of starfish are bioluminescent.The diameters of starfish vary from 2cm to 1metre.Starfish arms contain many small suction cups, called ambulacral pedicels, that make it possible for the starfish to move on the substrate.



Make sure to check out the Jellyfish. Their tanks are cylindrical and the water is moving inside because Jellyfish aren’t meant to come into contact with hard objects. In the wild, they float about the oceans on the tides and currents. The tanks mimic this pattern.
Most Jellyfish are harmless. If you got stung by a Moon Jellyfish it would be no more than an irritant. Some jellyfish, however, can kill.

– Jellyfish have no nerves; no blood, no heart and no brain, and their bodies consist 95% of water!

– The Moon Jellyfish eat tiny micro plankton and small shrimp called Artemia. These are also known as Sea Monkeys.


Cownose Ray:

Out of all the animals that you may find at SEA LIFE, the Cownose is, without a shadow of a doubt, the most playful! It has two frontal lobes in its head, and two little holes under the eyes, which make her look like a cow!

They can measure up to 2 meters (79 inches), have diamond-shaped body and are also known as golden rays. They like to rest on sandy bottoms where they sometimes hide and search for food, digging up small clams and oysters, their favourite snack, through a very effective strategy of alternating blowing and suction.
Usually they are harmless but, when feeling threatened, they can use their sharp spikes on the tips of their tails to do some damage!

Things To Do:

– Watch them swimming. No other fish beats their elegance. Some say that they resemble an airplane, gliding through the water, some find that they look like birds flapping their wings in a graceful undulating motion!

– Notice how it seems they are always smiling!

– It is highly interactive, it seems to respond to our behaviour. Get closer and find out what we’re talking about!


– Occasionally, they leap completely out of the water and beat against the surface, causing extremely loud strokes.

– Seen in clusters, during their biannual mass migrations (over 10 000 individuals), they look like giant swimming leaves!

– The embryo develops inside the mother, with its “wings” folded over the body and is initially fed by an egg yolk!
