description Sixgill Stingray Overview
The sixgill stingray (Hexatrygon bickelli) is a species of deepwater cartilaginous fish found in the Indo-Pacific region. It is the sole member of the family Hexatrygonidae and is anatomically distinguished from other stingrays by its six pairs of gill slits, whereas most rays have five. This rare species typically inhabits continental slopes and feeds on benthic invertebrates.
help Sixgill Stingray FAQ
Why is the sixgill stingray uniquely named?
The sixgill stingray is a deepwater cartilaginous fish uniquely distinguished by its six pairs of gill slits. This physical trait is highly unusual, as almost all other species of sharks and rays possess only five pairs of gill slits.
When was the sixgill stingray discovered?
The sixgill stingray was first described scientifically in 1980. Because it is a deepwater species, it remained elusive to marine biologists for many decades prior to its official classification.
Where do sixgill stingrays live?
This unique ray lives in deepwater environments, typically inhabiting continental slopes and deep ocean trenches where light is minimal. Their biology is specially adapted to withstand the intense pressure and cold temperatures of these deep-sea habitats.
Are sixgill stingrays dangerous to humans?
Like other stingrays, they possess venomous barbed spines on their tails, but they are not considered a threat to humans. Because they reside in extreme deep-ocean depths, they rarely, if ever, interact with swimmers or beachgoers.
