Q & A

What unique ability do flying fish possess that aids in their escape?
-Flying fish have the unique ability to get airborne with an extra thrust from their tails, allowing them to glide for hundreds of meters when they are pursued by predators.
What predators pose a threat to flying fish when they are in the air?
-Frigatebirds are the primary predators that pose a threat to flying fish when they are airborne. If the flying fish gain too much lift, they become easy prey for the frigates.
What is the average success rate of polar bears during this time of year?
-During this time of year, polar bears on average succeed only once in 20 hunts.
How does a polar bear hunt a seal to avoid detection?
-To prevent her scent from betraying her, a polar bear makes a wide sweep to get downwind of the seal and then tries to catch it underwater.
What challenges do polar bears face as summer continues with rising temperatures?
-As summer continues and temperatures rise, each hunt requires more energy, which drains the bears of their reserves. Food becomes harder to find, and they must expend more energy to hunt, further depleting their energy stores.
How do wolf packs ensure the survival of their young in the harsh northern environment?
-Wolf packs in the north ensure the survival of their young by working together. The young are raised not only by their parents but also by their aunts and uncles, collectively trying to ensure that each pup reaches near-adult size before the snow returns.
What is the strategy of wolves when hunting adult hares?
-When hunting adult hares, wolves work as a team. One wolf gets close enough to bite the hare's tail, while others run on either side to prevent the hare from changing direction. This coordinated effort increases their chances of catching the prey.
How does the Namib Desert's hotrod ant adapt to the extreme heat?
-The hotrod ant adapts to the extreme heat by using their long legs to raise their bodies above the scorching sand, which can reach 70 centigrade. They must keep moving to avoid overheating and dying like their prey.
What makes the army ant colony so effective in hunting?
-The army ant colony is effective in hunting because it acts as a superorganism with a sensory system of two million antennae, a skeleton made from the bodies of workers, a defense system of soldier ants, and a coordinated system for dealing with waste. They work together, transcending individual size, to flush out wildlife in the jungle.
How do dolphins hunt fish during low tide on a shoreline?
-During low tide, dolphins work as a team to surround fish, driving them towards the shore. They attack in perfect synchrony, creating a bow wave that carries their prey onto the muddy banks, making it easier to catch.
What is unique about the bridge-building behavior of Darwin's bark spider?
-Darwin's bark spider is unique in its bridge-building behavior because the female can produce a 25-metre long, continuous strand of silk that is blown into a single line by the breeze, creating a bridge. This bridge is used to construct the world's largest orb webs, up to two metres wide.
What is the significance of the silk produced by Darwin's bark spider?
-The silk produced by Darwin's bark spider is significant because it is the toughest natural fiber on the planet, tougher than steel. This allows the spider to build large orb webs and bridges that can span wide rivers, essential for their hunting and survival strategy.
