Posterior anatomy of a stingray. (1) Pelvic Fins (2) Caudal Tubercles (3) Stinger (4) Dorsal Fin (5) Claspers (6) Tail. The venom of the stingray has been relatively unstudied due to the mixture of venomous tissue secretions cells and mucous membrane cell products that occurs upon secretion from the spinal blade. The spine is covered with the ...
The common stingray has a plain coloration and mostly smooth skin. The common stingray has been reported to reach a width of 1.4 m (4.6 ft) and a length of 2.5 m (8.2 ft), though a width of 45 cm (18 in) is more typical. [8] The flattened pectoral fin disc is diamond-shaped and slightly wider than it is long, with narrowly rounded outer corners ...
Unlike many other stingrays, this species seldom buries itself in sand. [13] The bluespotted ribbontail ray excavates sand pits in search of molluscs, polychaete worms, shrimps, crabs, and small benthic bony fishes; when prey is located, it is trapped by the body of the ray and maneuvered into the mouth with the disc.
Batomorphi is a clade of cartilaginous fishes, commonly known as rays, this taxon is also known as the superorder Batoidea, but the 5th edition of Fishes of the World classifies it as the division Batomorphi. [2]
The southern stingray (Hypanus americanus) is a whiptail stingray found in tropical and subtropical waters of the Western Atlantic Ocean from New Jersey to southern Brazil. [2] It has a flat, diamond-shaped disc, with a mud brown, olive, and grey dorsal surface and white underbelly (ventral surface). [ 3 ]
For over a hundred million years, the stingray has roamed the world's oceans as an almost mythological animal: extraordinarily graceful, yet potentially lethal.
A minority of authors place this species with the river stingrays in the family Potamotrygonidae. [1] Preliminary morphological examination has suggested that the round ribbontail ray is more related to Dasyatis and Indo-Pacific Himantura than to the congeneric bluespotted ribbontail ray ( Taeniura lymma ), which is closer to the amphi-American ...
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
