 Attenborough\n\nThis first Episode discusses the keys to success of 
 reptiles and amphibians, looking at thermoregulation, parental care and the 
 time-scales on which reptiles operate.  David Attenborough begins in the 
 Galapogos Islands, using thermal imaging to demonstrate how marine iguanas 
 warm their bodies by basking in the sun before feeding.  Meanwhile, the 
 lizard inhabitants of a Minorcan island have a relationship with its 
 indigenous dead horse arum plants.  David visits Dassen Island to witness 
 one of the world’s greatest concentrations of tortoises — around 5,000 
 of them.  Few reptiles are active at night, but crocodiles can rely on 
 water that retains much of its daytime temperature.  Conversely, 
 amphibians’ moist skin would be damaged by the sun and so most of them 
 are nocturnal.  An exception to this is the waxy monkey leaf frog, which 
 can deal with sunlight by covering its body in a wax secretion.  A puff 
 adder illustrates the relative inactivity of reptiles compared to mammals:  
 one large meal can last up to a year. When it hatches at the onset of 
 winter, the young painted turtle stays underground, near frozen until the 
 spring when it can emerge.  David wonders if the dinosaurs’ immense size 
 allowed them to maintain warm blood.  The largest living reptile is the 
 leatherback turtle and indeed is able to be so large because of insulating 
 body fat.\n\nWheelchair accessible around the corner at  411  28th
