Pearly razorfish

Scientific name: Xyrichtys novacula

Pearly razorfish measures between 15 and 20 cm, although males can reach up to 30 cm. Their elongated shape allows them to quickly hide under the sand to flee from predators, sleep, and hibernate. It feeds on shellfish and crustaceans.

Curiosities

It is highly appreciated in the Balearic Islands, especially in Ibiza, so the ban is lifted for a few days as fishermen attempt to catch it.

Red mullet

Scientific name: Mullus surmuletus

Its coloration varies according to age, environment, depth and mood. It lives on soft, sandy ground and sometimes on rocky bottoms. To feed, it uses the two sensory barbels, stirring the sand to look for its prey.

Curiosities

It swallows the sand to filter it and expels it through the bronchi, retaining the food as small fish and crustaceans.

Oblade

Scientific name: Oblada melanura

It is a fish that lives near the coast between 5 and 20 meters deep both in rocks and in underwater grasslands. It feeds on small crustaceans, fingerlings, and worms. We often see them as they like to approach boats anchored on sandy bottom.

Curiosities

They always swim in a group and in a very orderly way. To eat they rise to the surface and as they are omnivorous we like to feed them in our boat trips.

Painted comber

Scientific name: Serranus scriba

It lives in shallow waters of up to 30 meters between rocks and areas of sand and posidonia, although sometimes we can see them inside sponges. They spawn near the shore leaving the eggs attached to the rocks at the bottom. They are carnivorous fish.

Curiosities

They are a very curious fish who like to stare at the diver and also like to observe octopuses when they move about the bottom of the sea.

Sea cucumber

Scientific name: Holothuria forskali

We find them at depths of up to 70 meters and it travels with three rows of feet and suction cups. Sea cucumber feeds on small organisms that are ingested at the same time as the sand, once the organic matter it contains is used it expels the rest.

Curiosities

For self-defense purposes, it can expel the entire digestive tract and then regenerate it.

Rainbow wrasse

Scientific name: Coris julis

While females are brown and orange, males have predominantly greenish tones with an orange line. They are found in rock bottoms up to 50 meters deep and are not greater than 25cm. They feed on sea urchins and crustaceans.

Curiosities

The females form groups to feed while the males are lone predators. They are also called maids because they clean the impurities of other larger fish with their teeth.

Ornate wrasse

Scientific name: Thalassoma pavo

We find them on rocky bottoms and posidonia meadows. Females display vertical blue lines on their backs while males have a dark red head with green lines. They both feed on small shellfish and crustaceans and they are fast swimmers due to the frantic movement of their pectoral fins.

Curiosities

As a fish that seeks warm waters, it is becoming more frequently seen due to gradually increasing ocean temperatures.

Curiosities

They are of considerable fishery importance, and are often artificially reared on marine fish farms.

Neptune grass

Scientific name: Posidonia oceanica

It is an aquatic plant with roots, trunk, leaves, flowers and fruit. It is endemic to the Mediterranean and we always find it in well-lit areas up to 80 meters deep. Neptune grass takes root on the sand bottoms, fixing it, which is why it is very important in the creation of beaches.

Currently the Posidonia meadows are in clear regression due to water pollution, trawling and boat anchoring. It houses up to 400 types of algae and thousands of animal species.

Curiosities

Neptune grass suffers greatly in polluted waters, so they are indicators of the environmental quality of the water. Historically they have been used to build the roofs of local houses due to their insulating capacity and their ability to prevent the reproduction of bugs.

Sea urchin

Scientific name: Paracentrotus lividus

Urchins are found from just below sea level to depths of 20 meters. It occupies deep, round cavities in soft rocks that it enlarges as it grows. It is herbivorous and feeds on algae, which it sometimes covers with to protect itself from intense light.

Curiosities

They move through the rocks at a speed of 1 meter a day to feed and return to their resting point on the rock.
