High blood pressure symptoms, signs and risks. High blood pressure, or hypertension, doesnât usually cause any obvious symptoms. The British Heart Foundation estimates that up to 5 million people in the UK have undiagnosed high blood pressure. Left untreated, hypertension can lead to serious diseases, including stroke, heart disease, kidney failure and eye problems.
Ringneck Snake (Diadophis punctatus) Description: Ringneck snakes are small -- 10 - 15 in (25 - 38 cm) -- slender snakes that are generally grayish with a yellow or orange band around the back of the neck and a yellow or orange underside. Two subspecies are found in our region.
The green anaconda is the largest snake in the world, when both weight and length are considered. It can reach a length of 30 feet (9 meters) and weigh up to 550 pounds (227 kilograms). To picture how big that is, if about five ten-year-olds lie down head to foot, they'd be about the length of this huge snake. And it'd take about 11 kids to weigh as much as one anaconda.
