Dipturus bullisi (lat.) Is a species of cartilaginous fish of the rhombic family of rays of the order of stingrays. They live in the central western and southwestern parts of the Atlantic Ocean . They are found at a depth of up to 549 m. Their large, flattened pectoral fins form a rhombus disk with an elongated and pointed snout. The maximum recorded length is 77 cm. Eggs are laid. They are not the target fishing target [1] [2] [3] .

Content
The species was first scientifically described in 1962 as Raja bullisi [4] . The species is named after the marine biologist Harvey R. Bollis, who helped to collect materials for the study of the rays of the Gulf of Mexico.
These bathydemersal stingrays live in the Gulf of Mexico off the coast of Brazil , Colombia , Honuras , Panama , USA ( Florida , Texas ), Venezuela and Bolivia . They are found along the outer edge of the continental shelf and in the upper part of the continental slope at a depth of 183 to 549 m [2] .
The wide and flat pectoral fins of these rays form a rhombic disk with a rounded snout and rounded edges. On the ventral side of the disc are 5 gill slits, nostrils and mouth. On the long tail there are lateral folds. These skates have 2 reduced dorsal fins and a reduced caudal fin [1] . The dorsal surface of the disc is even light brown; the ventral surface is dark brown. The area on the snout where the ampullar pores are concentrated is darker to the posterior edge of the lower jaw. There are orbital and occipital spines [5] .
The maximum recorded length is 77 cm [4] .
Like other rhombic, these stingrays lay eggs enclosed in a rigid horn capsule with protrusions at the ends. Embryos feed exclusively on yolk [3] . Males reach puberty with a length of about 76 cm. Length when hatched 17 cm [2] .
These skates are not subject to targeted fishing. Potentially by- catch . For the assessment by the International Union for Conservation of Nature of the conservation status βthe type of data is not enough.
