Halteria (called by See also: A See also:good See also:account of the habits of the tuatara has been given by See also:Newman . They live upon animals, but these are only taken when alive and moving about, e.g. See also:fish, See also:worms, See also:insects . Sluggish in their habits, they See also:sleep during the greater See also:part of the See also:day in their self-dug burrows, and are very fond of lying in the See also:water, and they remain below for See also:hours without breathing . Each individual excavates its own hole, a See also:tunnel leading into a roomy chamber, lined with grass and leaves; part of the habitation is shared socially by a See also:family of petrels, which is said to occupy usually the See also:left See also:side, whilst the tuatara itself lives a solitary See also:life . The male croaks or grunts much during the pairing See also:season; the hard-shelled, See also:long-See also:oval eggs, about 28 mm. long, are laid in holes in the See also:sand, about ten in one See also:nest, from See also:November to See also:January or See also:February . They contain nearly ripe embryos in the following See also:August, but they are not hatched until about thirteen months old; in the meantime they seem to undergo a See also:kind of See also:hibernation, their nasal See also:chambers becoming blocked with proliferating epithelium, which is resolved shortly before hatching during the See also:southern summer . In spite of their imposing, rather See also:noble appearance, when, with their heads erect, they calmly look about with their large quiet eyes, they are dull creatures, but they bite furiously .
