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 average size of a green tree snake's clutch can range between five and 12 eggs. When these snakes are full grown, they can range between 3 and 5 feet, with some very large specimens growing to be 6.5 feet. Green tree snakes are diurnal hunters and have keen eyesight.
