Bothrops alternatus
Bothrops alternatus is a venomous pit viper species found in Brazil, Paraguay, Uruguay and Argentina. Within its range, it is an important cause of snakebite. The specific name, alternatus, which is Latin for "alternating", is apparently a reference to the staggered markings along the body. No subspecies are currently recognized.
Description
Size
Large and stout, this terrestrial species reportedly exceeds 2 m (6.6 ft) in total length, although the verified maximum is 169 cm (67 in). Most specimens are 80–120 cm (31–47 in) in total length, with females being significantly longer and heavier than males.
Color and markings
The scalation includes 25-35 (usually 27-31/29-33 in males/females) rows of dorsal scales at midbody, 155-183/164-190 ventral scales in males/females, and 38-53/30-44 subcaudal scales in males/females. On the head there are 8-13 strongly keeled intersupraocular scales, 8-10 supralabial scales, none of which are fused with the prelacunal, and 12-14 sublabial scales.
Yarara (disambiguation)
Yarara or Yarará is the common name of the venomous pit viper species Bothrops jararaca endemic to southern Brazil, Paraguay, and northern Argentina. Also known as Yarará perezosa (Argentina), jararaca (Brazil)
Yarara may also refer to:
Nostromo Yarará
The Yarará project is the first unmanned aerial vehicle (UAV) programme in South America to be produced in series and for export. The system is developed by Nostromo Defensa for surveillance, border patrol and reconnaissance. It was unveiled at the Air Show of the Argentine Air Force (Fuerza Aérea Argentina, FAA) on 10 August 2006. The manufacturer says it has been produced in small series for export to an unidentified government customer in the United States.
Design
The vehicle was named after the yarará, a South American snake.
Yarara was developed by Nostromo-Defensa under contracts from the US Southern Command with a system comprising three aircraft delivered in June 2006.
Evolution of the design has seen an increase in the width of the undercarriage footprint to support rough field landings, while a Zenoah 6.5hp engine is an option. The first powerplant is a Modellmotoren 3W 5.5hp two stroke system.
The current Yarara is powered by a single Sonic 35 multifuelled air-cooled wankel rotary engine which produces 5.9KW of output power. It is fitted with a three-bladed propeller at the rear of the fuselage section raised on an engine pylon with integral fuel tank. This engine is designed and built by British Company Cubewano. It is the first kerosene-functioned (heavy fuel) rotary engine flown on a UAV that can JP8 as fuel. It was first flown in this configuration in August 2009.
