The physiology of underwater diving is the physiological adaptations to diving of air-breathing vertebrates that have returned to the ocean from terrestrial lineages. They are a diverse group that include sea snakes, sea turtles, the marine iguana, saltwater crocodiles, penguins, pinnipeds, cetaceans, sea otters, manatees and dugongs.
The pungi [3] [4] [5] is a Hindu folk music reed pipe instrument [6] that is mostly played by cobra charmers [7] in Sindh and Rajasthan. [8] The instrument is made from a dry hollowed gourd with two bamboo attachments. [9] It is also a double-reed instrument. [10] The pungi is played by Jogi in the Thar desert. [11]
The other was designed for closed bell bounce diving and allowed for exposures up to 120 minutes, and depths to 120 m. The diver breathed heliox in the water and in the bell, air after transfer into the deck decompression chamber, and finally oxygen on built in breathing system (BIBS) from 12 m to the surface.
Litters of 20–40 are common, [5] although fewer offspring may occur, as few as one. [17] The reported maximum is 75 [24] in a single litter. At birth, juveniles are 215–260 mm (8.5–10.2 in) in total length. The minimum total length for a gravid female is about 100 cm (39 in). It seems that sexual maturity is achieved in 2–3 years.
X-ray showing the skeleton of Typhlonectes (Typhlonectidae). Caecilians' anatomy is highly adapted for a burrowing lifestyle. In a couple of species belonging to the primitive genus Ichthyophis vestigial traces of limbs have been found, and in Typhlonectes compressicauda the presence of limb buds has been observed during embryonic development, remnants in an otherwise completely limbless body.

[2] [3] [4] Marine gastropods that have a siphon are either predators or scavengers. [5] Although in gastropods the siphon functions perfectly well as a tube, it is not in fact a hollow organ, it is simply a flap of the mantle that is rolled into the shape of a tube. [1]
The pneumostome or breathing pore is a respiratory opening of the external body anatomy of an air-breathing land slug or land snail. It is a part of the respiratory system of gastropods. It is an opening in the right side of the mantle of a stylommatophoran snail or slug.
The game's concept was inspired when lead designer Jordan Itkowitz had a dream about using the Wii Remote to control a snake, slithering through the grass and striking a mouse. [6] In brainstorming, the idea of the snake and other creatures were left on the cutting room floor, leaving the scorpion and tarantula.
