The yellow stingray (Urobatis jamaicensis) is a species of stingray in the family Urotrygonidae, found in the tropical western Atlantic Ocean from North Carolina to Trinidad. This bottom-dwelling species inhabits sandy, muddy, or seagrass bottoms in shallow inshore waters, commonly near coral reefs. Reaching no more than 36 cm (14 in) across, the yellow stingray has a round pectoral fin disc and a short tail with a well-developed caudal fin. It has a highly variable but distinctive dorsal color pattern consisting of either light-on-dark or dark-on-light reticulations forming spots and blotches, and can rapidly change the tonality of this coloration to improve its camouflage. Relatively sedentary during the day, the yellow stingray feeds on small invertebrates and bony fishes. When hunting it may undulate its disc to uncover buried prey, or lift the front of its disc to form a "cave" attractive to shelter-seeking organisms. This species is aplacental viviparous, meaning that the developing embryos are sustained initially by yolk and later by histotroph ("uterine milk"). Females bear two litters of up to seven young per year in seagrass, following a gestation period of 5–6 months. Though innocuous towards humans, the yellow stingray can inflict a painful injury with its venomous tail spine. This species is taken as bycatch by commercial fisheries and collected for the aquarium trade; it may also be negatively affected by habitat degradation. Nevertheless, it remains common and widespread, which has led the International Union for Conservation of Nature (IUCN) to list it under Least Concern.

This knot is called a round turn and two half hitches. And the round turn of two half hitches is a fantastic knot for tying on fenders. This is a short lesson from our Catamaran sailing Masterclass knot tying lesson. http://masterclass.nautilussailing.com It's also a great knot for tying your dinghy up to a piling. So here are the steps to do a round turn and two half hitches. You go all the way around your stanchion or the dock post, leave quite a bit of tail. So there's our round turn we like to go over and you come back through that triangle, tighten it up, and the second time we come under. And then back over and that tightens it up. And that's a clean looking round turn, two half hitches. And you can see how that is a real strong, solid knot that's gonna hold your fenders or your dinghy to a dock.
