Includes hissing loudly, spreading of the neck to appear larger and playing dead. The harmless Eastern Hog-nosed Snake is also well known for it acting ability, which The pattern and coloration of the eastern hognose snake can vary greatly. When compared side by side as in the photo below, it isĭifficult to understand how this mistaken identity occurs.Ī - If the rostral scale (nose) is upturned and pointed, then the snake is a harmless Eastern Hog-nosed Snake ( Heterodon platirhinos). ** Note: Often the harmless Northern Watersnake and Brown Watersnake are mistaken for the venomous Northern Cottonmouth. Then the snake is a Northern Copperhead ( Agkistrodon contortrix mokasen).ī - If the body is black to olive, usually with a series of crossbands and Brown stripe on side of head the snake is an Eastern Cottonmouth ( Agkistrodon piscivorus piscivorus). Northern copperheads are found statewide.Ī - If the body is reddish to light brown with darker hourglass-shaped cross bands, Heat sensing pits - Click Here - Section 2ĭistribution of the Timber Rattlesnake in VirginiaĪ - If the dorsal scales on the head small and/or snake has a rattle, then the snake is a Timber Rattlesnake ( Crotalus horridus).ī - Dorsal scales on head enlarged, no rattle - Click Here - Section 3 Heat sensing pits - Click Here - Section 4 Each snake identification page has two options, A and If test_rect.The identification keys are based on color, pattern and other (r.left, r.bottom-width), (r.right-width, r.bottom-width), Window = _mode((400, 400))ĭef drawOutline(surf, rectangles, color, width): However, I would like to specify the exact rectangular area to be filled. draws a line between 2 coordinates and inflates the line on both sides. Instead of drawing thick lines with I decided to draw rectangles thinly with. This method returns the index of the first rectangle in the list where a collision was detected, otherwise -1. In my solution, I choose to move the rectangle by 1 to one side and check that the rectangle does not collide with any of the adjacent rectangles. Therefore, a rectangle must be modified, it can either be inflated on one side or moved to one side. Since the rectangles do not overlap, they do not collide and a collision check fails. Iterate through all rectangles and create a list of adjacent rectangles: for i, r in enumerate(rectangles): Basically, for each side of a rectangle, you need to check if it is docked to another rectangle in the list, and draw a line segment along that side if it is not docked. ![]()
