Ophionyssus natricis, the reptile mite, is a parasitic mite most commonly found on snakes, but also occurring on captive lizards, turtles, crocodiles, and other reptiles. [1] The parasites feed on snakes, which cause the bodies of the mites to be engorged with blood and fluids from the snake.
Snake scales are formed by the differentiation of the snake's underlying skin or epidermis. [7] Each scale has an outer surface and an inner surface. The skin from the inner surface hinges back and forms a free area which overlaps the base of the next scale which emerges below this scale. [8] A snake hatches with a fixed number of scales.
Just prior to shedding, the skin becomes dull and dry looking and the snake's eyes turn cloudy or blue-coloured. The old layer of skin splits near the mouth and the snake wriggles out, aided by rubbing against rough surfaces. In many cases the cast skin peels backward over the body from head to tail, in one piece like an old sock.

After maturing and mating within the host, the males die and females (length 70–120 cm or 28–47 in) migrate in subcutaneous tissue towards the skin's surface. Around a year after the infection, the female causes the formation of a blister on the skin's surface, generally on the lower extremities, though occasionally on the hand or scrotum.
Female red-eyed crocodile skinks have two working ovaries, but only the right oviduct is functional; therefore, eggs from the left ovary must migrate across the body cavity prior to oviposition. [5] She often curls around the egg and aggressively defends it when approached by a perceived threat. If it is uncovered, she will cover it back up. [6]
