Adults face every-day threats from a wide assortment of possible predators, including birds, mammals, and reptiles. Tadpoles face predation from fish, aquatic insects, birds, turtles, and snakes. Chytridiomycosis caused by chytrid fungus, an infectious disease of amphibians, has had a detrimental effect on Mississippi gopher frog populations. [1]
Ophidiomyces ophidiicola (formerly Ophidiomyces ophiodiicola) is the cause of ophidiomycosis also known as snake fungal disease or SFD in some species of snakes. [1] It is a keratinophilic fungus from the family Onygenaceae of the order Onygenales. O. ophidiicola is an emerging pathogen of captive and wild snakes in North America and Europe. [2]
These small fish maintain so-called "cleaning stations" where other fish, known as hosts, will congregate and perform specific movements to attract the attention of the cleaner fish. [26] Cleaning behaviours have been observed in a number of other fish groups, including an interesting case between two cichlids of the same genus, Etroplus ...
The following is a list of aquarium diseases. Aquarium fish are often susceptible to numerous diseases, due to the artificially limited and concentrated environment. New fish can sometimes introduce diseases to aquaria, and these can be difficult to diagnose and treat. Most fish diseases are also aggravated when the fish is stressed.
This category is dedicated to the various Fish diseases. For an overview of this subject go to Fish diseases. Subcategories.
Pacific gopher snakes prefer warmer temperatures, ideally around 75 to 90 °F (24 to 32 °C), and drier habitats such as meadows, fields and agricultural farmlands. [13] They are seldom found in dense forests or cold environments. To maintain warm internal temperatures, Pacific gopher snakes will often bask in sunlight on rocks.
Adult gopher snakes average between 36-84 in (91–213 cm) in length, or up to 6 or 7 feet, when fully mature. [5] Dorsally, gopher snakes are yellowish or a light, sandy brown, with a series of large, dark brown or black markings and smaller, darker spots along the sides.
In all snakes of the genus Pituophis, the epiglottis is peculiarly modified so that it is thin, erect and flexible. When a stream of air is forced from the trachea, the epiglottis vibrates, thereby producing the peculiarly loud, hoarse hissing for which bullsnakes, gopher snakes, and pine snakes are well known.
