Durban hinge-beak shrimp
COMMUN NAME IN FRENCH: Crevette danseuse or crevette à long rostre or Crevette danseuse de Durban ENGLISH NAME : Durban hinge-beak shrimp
LATINE NAME : Rhynchocinetes durbanensis
FAMILY : Rhynchocinetidae
In the exhibition: the Durban hinge-beak shrimp can be viewed in the Biodiversity Area, after the Tropical Lagoon.
Geographic distribution: The circumtropical Indo-Pacific.
Habitat: The Durban hinge-beak shrimp prefers to live in groups of sometimes as many as 100 individuals in the gaps and cavities of coral reefs or on the underside of overhangs, at depths of between 2 and 40 m.
Description : it is characterised by its very long rostrum. The male’s pincers are much larger than those of the female.
Diet: the Durban hinge-beak shrimp is both carnivorous and omnivorous.
Size: from 1 to 5 cm
Threats and protective measures: the Durban hinge-beak shrimp is not currently listed as an endangered species by the IUCN. http://www.iucnredlist.org/apps/redlist/search
Species characteristics and ability to occupy an ecosystem niche in the context of biodiversity: the French call the Durban hinge-beak shrimp the ‘dansing shrimp’ because of the way it moves. It lives in groups, is nocturnal and hides itself away to molt.
Resilience: like all crustaceans, shrimps grow to adulthood by metamorphosis and by molting. Molting also enables crustaceans to replace a damaged appendage, or one lost in combat. The new appendage will usually be smaller than the original one.
Services provided to humanity in the fields of medical research, pharmaceutical and cosmetic products: the shells of crustaceans contain chitin. This substance, which is processed to create chitosan, possesses a wide range of extremely useful properties.
Some examples of its applications:
- medicine (surgical thread anti-rides),
- dental surgery (coatings for dental implants - aiding healing and reducing the risk of rejection),
- cosmetics (anti-wrinkle).
