Fast Facts: Atlantic Green Turtle

-

A New Year brings fortune, happiness, and luck. What better species is there to start off 2023 than the turtle? 

The Atlantic Green Turtle : Chelonia mydas

Description: One of the most identifiable turtles in the world, the Atlantic Green Turtle has an un-ridged smooth shell that varies from light brown to olive green with dark brown mottling and hexagonal markings resembling plates. Sizes range from 35-48 inches in length and 300-350 pounds in weight; the Atlantic Green Turtle is the largest hard-shelled sea turtle in the world. Its four flippers each have one claw, and every Green Turtle has a tail, although males typically have longer and thicker tails. There is no notable size difference between males and females. 

Habitat: The Atlantic Green Turtle is most often found in the shallow coastal waters of coral reefs, bays, and inlets near the western and eastern US coasts. However, their distribution ranges from all over the world, and Atlantic Green Turtle nesting sites are located in the waters of over 80 countries.

Diet: As the only herbivores of sea turtles, the Atlantic Green Turtle's diet consist of almost entirely of seaweed (sea grasses) and green algae. Occasionally, they will also eat crustaceans and jellyfish. 

Behavior: Female Sea turtles are known to return back to their nesting sites to lay their eggs (which number around 110-150). After hatching, the hatchlings make their way over a stretch of sandy beach to reach offshore (open ocean) areas, where they'll spend the rest of their lives. The hatchlings are able to determine where the ocean is because of an innate instinct to crawl toward the brightest area, the ocean, and away from the shaded vegetation of the land. Besides mating which occurs during the breeding season on foraging grounds, Atlantic Green Turtles are solitary. Additionally, they'll travel thousands of miles from foraging to breeding grounds, where multiple females may gather to lay eggs. A female may be anywhere from 25-45 years old before she breeds; this is unsurprising as Green Turtles can live up to 70 years. And every two to five years, females will return to breeding sites to lay eggs again. 

Conservation Status: The conservation status of the Atlantic Green Turtle is in between Endangered and Threatened, depending on the region, but it is officially considered to be Endangered. Major threats to this species include shore development, which disturbs the nesting sites that the turtles return to each breeding season, and commercial fishing, which involves machinery and nets that harm wildlife. Pollution is another problem as marine wildlife may swallow or get tangled in plastic that is tossed into the ocean. 

Unique Traits:  It may be obvious to some that the Atlantic Green Turtle is not actually green (it's a new year, I had to sneak in some sarcasm.) As stated above, the Atlantic Green Turtle is often brown or olive colored; its name actually comes from its green fat and cartilage and not its outward appearance. Also, Atlantic Green Turtle heads are typically considered to be small in comparison to their bodies and other turtles. However, Atlantic Green Turtle heads are unable to retract despite their small size because their flat shells provide no room for retraction. This is unusual as other turtles are able to retract their heads. Note that no sea turtles are able to retract into their shells.

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, t he 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 t

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
