Ginglymostoma unami, also known as the Pacific nurse shark is a nurse shark of the family Ginglymostomatidae. It is found in southeastern coast of Baja California, Mexico to Costa Rica including Gulf of California. It is 2.8 meters long. This species differs from Ginglymostoma cirratum between posterior end of the second dorsal fin and the beginning of the caudal lobe, both being shorter; the new species also differs by the position of the insertion of the first dorsal fin with regard to the pelvic fins and in the form and number of keels on the dermal denticles and teeth morphology. The Ginglymostoma unami was previously recognized as G.cirratum exhibiting a divided distribution of a species in the northern half of the Atlantic Ocean. However, that species is now considered to be restricted to just the Atlantic Ocean.[2]

They don't work in a hospital but they might draw blood! I'm Jonathan Bird and this is Shark Academy! The Nurse shark is a somewhat sluggish shark that is often seen resting on the bottom. Far from being a medical professional, this shark's common name is derived from the Old-English word for a "sea floor" shark: "Hurse" The Nurse shark reaches about 10 feet in length but generally ignores people. They are considered totally harmless unless divers annoy them--in which case they actually can bite. The teeth are small but numerous. The Nurse shark’s small mouth is sometimes used to feed by suction. Its favorite food is the conch, which the shark can slurp right out of the shell!
