Let's Hear it for the Humphead Wrasse
The humphead wrasse, Cheilinus undulatus, is also known as the Māori wrasse, Napoleon wrasse, or the blue- tooth grouper. They can usually be found around coral reefs and steep rocky cliffs in the Indo-Pacific, particularly on the east coast of Africa, the west coast of India, and the tropical waters of southeast Asia and the Great Barrier Reef.
The Māori wrasse gets its name from the distinctive markings that adults carry. Males are blue-green or purple, while females are more often red or orange. Both have unique patterns of lines and dots covering their heads, and stripes running down the rest of their body; early researchers compared the patterns on their heads to the tattoos traditionally used by the Māori people. In addition to its striking coloration, C. undulatus is also known for being the largest member of the wrasse family. Males can reach up to 2 m (6.5 ft) long and weigh up to 180 kg (396 lbs), while females tend to be smaller. Males also have a large 'hump' on their foreheads, hence the name humphead wrasse.
Another feature of note in C. undulatus is the set of large teeth fused into a parrot-like beak. They use this beak to predate upon hard-shelled animals like mollusks, urchins, sea stars, and crustaceans. On occasion, they also feed on smaller fish and moray eels. Due to their size, adults have very few natural predators aside from sharks, but larvae and small juveniles are more often opportunistically hunted by other fish.
Like many coral reef fish, the humphead wrasse is a protogynous hermaphrodite. This means that most individuals begin life as a female, and become male later in life-- known as 'super males', they are larger than males who did not transition. Individuals first become sexually mature at 5-7 years old, and females begin transitioning to male at 9-12 years old. Spawning occurs a few times a year, and during this period over a hundred adults can congregate in an area. The female releases about 20 eggs into the water column, where they are fertilized by her chosen partner. Three to four weeks later, the eggs hatch and the larvae migrate to the nearby reef.
Conservation status: C. undulatus is considered Endangered by the IUCN. Populations have declined due to overfishing and by-catch mortalities, loss of their food sources, habitat destruction, and capture of juveniles for the aquarium trade.
If you send me proof that you’ve made a donation to UNRWA or another organization benefiting Palestinians– including esim donations– I’ll make art of any animal of your choosing.
