How do animals adapt to warm environment

1. Sweating 2. Panting 3. Saliva spreading 4. Retreating in caves of burrows 5. Dormancy (estivation) 6. higher Body To (eg. Camels: as high as 40°C) 7. Fur

present in humans & chimpanzees

Sweat glands

Sweating - duckbill platypus - deer - mice, rats, cats

snout, base of tail, paws

- low volume - high in Hb - resists influx or outflow of H20 (helps during drastic dehydration) - blood flows normally even when the tissues are dehydrated - also helps in hypoxic montane habitats

Bilaminar, oval wafer

How many advantages of high body temp. Cite one

1. Totally independent of environmental temperature (o°C - 45°C) 2. Faster CNS function (information acquisition, processing, and response) 3. Fast and coordinated biochemical reactions (enzyme-catalyzed) 5. Low muscular viscosity 6. cna be active at night

How many advantages of high body temp. Cite one

Energy expensive - have to feed daily

Nocturnal Existence

1. Big eyes 2. Packed with rods 3. Tapetum lucidum 4. Echolocation 5. Rely on sense of smell

- thick reflective membrane (15 cells wide) - collects and re-emits light back to the retina - gives rods a second chance to absorb the image information, thus maximizing the little light available to them. As this light is reflected off the tapetum, the animal's eyes appear to glow.

Tapetum lucidum

largest mammal living today; it is also the largest mammal to have ever lived.

Blue Whale

An adult can grow nearly as long as three school buses and weigh over 400,000 pounds - as much as 24 African elephants.
