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 is a video on a McKee Craft - yes, a McKee! I know, you haven't heard about these boats in a long, long time. But new ownership has taken over, and the McKee Craft boats are back. Fortunately, they construct these new models exactly as they did the old ones - a hull, a deck, and pressurized foam in-between, which cures into a one-piece boat. But the plot thickens, when you learn that McKee Craft is also building a line of larger boats, called the Aegis. We found one at the Fort Lauderdale Boat Show, and shot this short video to give you an introduction to the new McKees. http://features.boats.com/boat-content/2014/01/mckee-craft-and-aegis-first-look-video/ For more boat videos, visit www.boats.com.
