Cuckoo wrasse (Labrus mixtus) is a species of wrasse that belongs to the genus Labrus. They are often found in the Eastern Atlantic ocean, from Southern Norway to Senegal, Azores, and Madeira.
These fish are occasionally encountered in the Mediterranean Sea. They inhabit algal zones of rocky shores at depths of 30 to 80 meters.
Cuckoo wrasse is a non-migratory fish, which means they move according to the tide and depth of their home, but not long distances. These fish usually prefer solitary. However, it is normal to encounter them in pairs or with juvenile fish.
How Cuckoo wrasse looks like
Cuckoo wrasse is one of the most colourful fish that shows sexual dimorphism. There are distinct differences between males, females, and even juveniles.
The male fish has a blue head in an orange body. The body is covered with horizontal brilliant blue lines and mottled patterns. The tail is dark blue, while the other fins are covered with blue markings on the margins.
Juveniles and females are colored in a combination of pink, orange, and red.
However, females have three black spots on their back near the dorsal fin, which juveniles lack. They possess white coloration between the black spots, stretching to the tail.
The body of the cuckoo wrasse is slim and elongated, and it has a long, pointed head.
Like other wrasse species, they are ray-finned fish that have long dorsal spines on the back. Their eyes are big and round. Males have bigger heads than females do.
Cuckoo wrasse grows up to 16 inches maximum in length, with an average size of 12 inches. They are among one of the largest wrasse species.
Like most fish, their growth is faster when they are in their juvenile stage and gradually slows down in adulthood.
The female Cuckoo wrasses are usually smaller than the males. The maximum size of a female specimen is about 12 inches.
Cuckoo wrasse has a maximum life span of 20 years. Their average life expectancy is about 10 to 12 years in the wild.
Where Cuckoo wrasse lives ?
Cuckoo wrasse inhabits weedy and rocky areas near the coral reefs. They are found in the eastern Atlantic Ocean and the Mediterranean Sea.
It is common in the coastal waters of Norway, Senegal, Azores, and Madeira. They also occur in the Canary Islands and Cyprus but are absent from the Levantine Sea.
Cuckoo wrasse usually lives at the depths of 40 to 80 meters (130 and 260 ft), but you can also see them at a depth of 2 meters and 200 meters. They are non-migratory fish, so they live in a limited area.
Cuckoo wrasse prefers water temperature of 20 to 24 degrees Celsius (68-75 °F). Their pH preference ranges from 7.8 to 8.4, which is slightly alkaline.
Cuckoo wrasse behavior
Cuckoo wrasse prefers to live in solitary, but they may also live in pairs or with juvenile fish.
They prefer slightly deeper water than the Ballan wrasse and rarely occurs in shallow waters. However, juveniles occasionally live in shallower waters.
These fish become aggressive and territorial when breeding, and the males show parenting behavior, unlike most other wrasse species.
Cuckoo wrasses are protogynous hermaphrodites, which means they can change sex under certain circumstances. All cuckoo wrasse are born females.
When a wrasse group lacks a male for reproduction, the dominant female will transform into a male. Usually, there can be only one male in a group of cuckoo wrasse.
The group can sometimes lose the male when other fish predate on the male or die for different reasons. The dominant female fish takes about seven months for sex reversal.
Cuckoo wrasse eats plankton, crustaceans, mollusks, and worms with their tiny canine-like teeth. They also swallow sand to digest food better. When they mate, it is common for large males to chase smaller males away.
What does Cuckoo wrasse eat?
Cuckoo wrasse is carnivore fish, which means they feed on microscopic organisms or animals. This includes crustaceans, mollusks, worms, and even fishes. They also swallow sand to digest food better.
Cuckoo wrasse prefers feeding in the middle of the day when they are less visible because of sunlight.
Divers can sometimes see them during the daytime, but usually at night. Juveniles are more active in the early morning and late afternoon.
Cuckoo wrasse breeding
Cuckoo wrasses are oviparous, which means female cuckoo wrasse lay eggs instead of giving birth to live young. They spawn in a pair or a group.
The male and female cuckoo wrasse will circle each other for about an hour to figure out if they are ready for mating. Once they are ready, the male releases sperm, and the female releases eggs simultaneously.
For the spawning, the male builds a dish-shaped nest with algae, and that is where these fish lay their eggs. The female fish can lay up to thousand eggs in one spawn.
During the mating season, male cuckoo wrasse becomes territorial, and females are often chased away or attacked by the males.
Work on territory starts when they find their home in the algal zone. Males take every chance to fight with their neighbors to expand their territory. But this is done without much harm.
Once they finish spawning, the male fish guard the eggs until they hatch to protect them from predators, including other wrasse species.
Importance of Cuckoo wrasse
