The Mysterious and Endangered Pink Manta Ray

pink manta ray

The pink manta ray (Mobula granroostae) is a rare species of ray that is endemic to the waters off Australia’s north-western coast. The majestic creature has the unique and spectacular distinction of having a distinctive pink tinge to its otherwise light gray or silver skin. It is one of only two known species of Manta Ray that has this special coloration, and its population has been classified as “Critically Endangered” by the International Union for the Conservation of Nature (IUCN). 

Introduction to the Pink Manta Ray

The pink manta ray is a rare species of ray found primarily in the coastal waters of Australia and the Pacific Islands. They have gained a lot of attention in recent years due to their beautiful coloring, and have become increasingly popular with divers, photographers and animal lovers. Despite their delicate nature and fragile habitats, pink manta rays have managed to maintain a stable population.

The pink manta ray is a species of ray that is renowned for its incredible beauty and is a relatively new species of marine life to the scientific community. It is part of the Mobulidae family and is sometimes referred to as the pink dwarf manta ray. It was discovered in 2009 and was classified by its physical characteristics such as the pectoral fins that are about 1/3 the length of the wings and its broad-angled anterior part of its head. 

History of Pink Manta Ray

The pink manta ray was first observed in the late 19th century by early Australian explorers. Despite its long history in the region, very little was known about its behavior and distribution. In the mid-2000s, several scientific surveys of the pink manta ray population off the northwestern coast of Australia were undertaken, resulting in a better understanding of the species’ behavior, migratory patterns and numbers. 

Behavior and Ecology of Pink Manta Ray

The pink manta ray is typically found at depths of 40-60 m and tends to inhabit areas of broken coral and rocky habitats. The species typically travels in small groups of 1-4 individuals and may sometimes be seen gathering in large groups. The rays’ diet consists primarily of crustaceans and plankton. Pink manta rays can grow to an impressive width of up to 2.3 m and weigh up to 300kg. 


The main threats to the pink manta ray are over-fishing, pollution and habitat degradation. As its population is highly migratory, the pink manta ray may also be affected by oceanic currents and changing climate patterns. Due to its vulnerability, it is listed as Critically Endangered by the IUCN.


In order to protect the species, there is an increasing effort to establish protection areas along the species’ migratory paths. Furthermore, scientific research is also underway to gain a greater understanding of the pink manta ray’s habitat and behaviour, with a view to aiding conservation efforts. In Australia, the species is fully protected under state and federal law and targeted fishing for it is illegal.

Physical Appearance of Pink Manta Ray

Pink manta rays are the smallest species of manta ray, with adults reaching an average length of 6 feet and weight of up to 550 pounds. They have a large, rounded head and short, paddle-shaped fins that help them propel through the water. Pink manta rays get their unique coloring from their specialized diet of benthic crustaceans and small fish.

Habitat and Migration of Pink Manta Ray

Pink manta rays live primarily in the warm waters of the coastal ocean, near the coastlines of Australia and the Pacific Islands. During their yearly migration, pink manta rays are known to travel from one region to the next in search of new prey. It is thought that their range covers an area as wide as 5,000 miles, allowing them to explore various habitats throughout their lifetimes.

Reproduction and Social Behavior of Pink Manta Ray

Pink manta rays are usually solitary animals and tend to be shy and timid around humans. When breeding, males and females form groups and travel together to mate. Female manta rays give birth to up to eight live young per mating season. 

Characteristics and Distribution of Pink Manta Rays

The pink manta ray is one of the smallest manta ray species with a disc width of 2-3.3 m and a mass of up to 230kg. They can be easily identified by their bright pink color and the distinctive triangular marks found on their dorsal sides. The color of the pink manta ray varies from light to dark shades of pink depending on their age and habitat. The pectoral fins of the pink manta ray have also been known to light up with a pinkish hue. 

These creatures are typically found in warm tropical and subtropical waters of the Indian Ocean and Pacific Ocean. They are generally solitary animals, but during their reproductive period, large schools of these majestic creatures can be seen coming together. 

Feeding Habits and Predators

The pink manta ray has a diet of plankton, small fish, and crustaceans. It feeds by straining food from the water with its gill rakers. They have also been observed filter feeding on tiny particles in the water. The predators of the pink manta ray include sharks, large game fish, and sometimes orcas. 

Importance to the Marine Ecosystem

The pink manta ray is a top-level predator that helps maintain the balance of its local ecosystem by controlling the population of its prey. As a species, they are an important part of the ocean’s biodiversity and an integral part of the delicate ocean ecosystem. 

Conservation Status

The pink manta ray is considered to be vulnerable by the IUCN Red List due to fishing activities that can disrupt their migration patterns and disturb their fragile marine habitats. They are also frequently targeted by poachers due to their colorful bodies and elegant shapes, making their conservation status a matter of concern. 

Final Words

The pink manta ray is a species of manta ray that has captivated people’s hearts for many years due to its beautiful colors and graceful appearance. They are an integral part of the marine ecosystem, yet they are vulnerable to extinction due to human activities. Hopefully, with the help of organizations such as the IUCN Red List, we can protect and conserve these incredible creatures for generations to come.
