This sculpture of a giant oceanic manta is 5,5 meters long and contains approximately 5.500 fish hooks. For more information about this sculpture, the exhibition or sales enquiries, please contact us.

Mobula birostris is the largest known ray with a wingspan of up to 700 cm.

 

Giant manta rays are filter feeders, found worldwide in tropical and subtropical waters, where they tend to occupy pelagic, offshore habitats and productive coastlines.

 

Females normally give birth to a single pup, and, on average, the giant manta may produce only 4–7 pups during its estimated lifespan.

 

The global population size of the giant manta ray is difficult to assess, but in most regions, its population sizes appear to be small (< 1,000 individuals)

 

Giant mantas have been recently listed as Endangered on the IUCN Red List of Threatened Species. They are caught frequently as bycatch and have been increasingly targeted over the last decade as demand for their gill plates grows in Asian markets.

 

Their low reproductive rates and conservative life history characteristics make them highly susceptible to population declines, and fisheries are likely to be unsustainable even at low catch rates. In the few places where manta rays are protected, the number of individuals is stable.

 

As a threatened migratory species, giant manta rays would benefit from the implementation of cooperative international agreements to manage and protect its populations. Efforts should be put in place to reduce the unintentional capture of these rays and when they are caught, protocols should be in place for their safe release, to reduce the chances of post-release mortality.
