Fast Facts: Maori Wrasse

-

Known by many names, including the Humphead Wrasse and Napolean Wrasse, this fish is known as a king of the coral reefs. 
 

The Maori Wrasse : Cheilinus undulatus

Description: Reaching up to 2 meters in length and 180 kg in weight, the Maori Wrasse is the largest species in the Wrasse family. They are easily distinguishable by the hump on their foreheads, which become more prominent with age, as well as their puffy lips. Based on the age and gender of a Maori Wrasse, its color patterns vary from red and orange to yellow and green and blues. 

Habitat: Found in the Indo-Pacific's tropical waters, the Maori Wrasse tends to cling to the temperate-coastal habitats of Australia. Maori Wrasse can inhabit all types of reefs, from rocky reefs by the shore to off-shore reefs reaching depths of 60 meters. 

Diet: Maori Wrasse are carnivorous creatures that feed primarily on crustaceans, mollusks, and other benthic creatures. They may even eat smaller fish! Maori Wrasse are significant to the Great Barrier Reef's health as they prey on several predators of the reef's corals, including the Crown of Thorns Starfish. 

Behavior: Maori Wrasse typically form single male-female breeding pairs, although some groups may have multiple males. This species is considered to have a slower maturity to reproduction, around five to seven years; typically, Maori Wrasse can live up 30 years. Additionally, these fish are known to be protogynous hermaphrodites, organisms that can change genders from female to male. Some, not all, Maori Wrasse females may become male at around nine years of age. 

Conservation Status: Since 1996, the Maori Wrasse has been listed on the ICUN's endangered species list. Although numbers range from 50,000 to 100,000 individuals, the Maori Wrasse population is still under threat due to fish trade, loss of habitat, and destructive fishing practices. However, under the protection of CITES, the Maori Wrasse population has been better protected from illegal poaching. 

Unique Traits: This species is unique because its scales color patterns change as the fish matures. As juveniles, Maori Wrasse appear in shades of red-orange; similarly, full-grown female Maori Wrasse are also red-orange. However, males tend to develop blue-green coloring and bright blue markings along their foreheads and bodies as they age. These markings are reminiscent of tattoos seen in the Maori culture, hence the Maori Wrasse's name.

This fish is one of the most recognizable species in both the Great Barrier Reef and Gen Z's childhoods.    The Yellow Tang:   Zebrasoma flavescens Description : The Yellow Tang's bright full-body yellow coloration is what makes distinguishes it from other Tangs. They can grow up to around 8 inches in the wild and have a white barb used for defense and attack on each side of the base of their caudal fin; these barbs are considered to be modified scales of the Tang.  Habitat : A Yellow Tang lives in saltwater reefs all over the world, however, they are most commonly found near Hawaii; about 70% of the Yellow Tang population lives in these waters. This species is native to the Pacific Ocean but may also be found in the Atlantic Ocean.  Diet : As herbivores, Yellow Tangs feed exclusively on plants. Algae is their preferred food source, and Yellow Tangs may even eat the algae off of turtles as part of a symbiotic relationship.  Behavior : Although they do tolerate other individuals

   Not something you'd find at your local buffet.  The Giant Clam:   Tridacna gigas Description : As the largest mollusks in the world, Giant Clams can reach a size of four feet long and weight of 500 pounds. A Giant Clam's main feature, its shell, is made up of two halves that can open and close through use of a hinge. Although their shells range in various sizes, colors, and patterns, all Giant Clams have a fleshy interior mantel that can weigh up to a quarter of the clam's weight! Habitat : These mollusks are primarily found in waters of down to 20 meters in depth in the Indo-Pacific region and other tropical and subtropical areas. Because of their shallow environment, Giant Clams thrive in coral reefs where they embed themselves into the sand. In particular, they thrive in habitats with high calcium carbonate levels that strengthen their shells.  Diet : Through the filter feeding process, Giant Clams gain energy from their main diet of phytoplankton. However, Giant Clam
