Fact Hunters: Dolphins, chocolate and brains

Did you know that dolphins can talk to each other? When the going gets tough, for instance, some dolphins call for backup. After being bullied by a duo of bottlenose dolphins, some spotted dolphins have been seen returning to the scene the next day with a few pals to chase and harass the bullies!

Amazingly the word chocolate comes from an Aztec word xocolatl… which means bitter water. This is rather odd, as chocolate tastes very nice. In America 71% of people prefer milk chocolate. The best type is dark chocolate; it is high in antioxidants that help to prevent heart disease and cancer.

Incredibly the Ancient Egyptians stumbled upon penicillin thousands of years before Alexander Fleming made the discovery official. They realized that putting mouldy bread on a wound helped it to heal more quickly.

Did you know that the human brain weighs approximately 3.0 pounds? Amazingly the brain takes the longest of any organ to develop and goes through more changes than any other organ.

Did you know that spiders use silk for a variety of jobs? These include:
  • Swathing silk for the wrapping and immobilisation of prey. 
  • Webs for catching prey using sticky silk - it is elastic to prevent the prey from rebounding off the web.
  • Draglines which are used to connect the spider to the web, as safety lines in case a spider should fall and as the non-sticky spokes of the web. 
  • Parachuting or ballooning which is used to aid the dispersal of young and to find new areas as a food source.

Ethan has been finding out about ticks. Did you know that ticks are arachnids? They are more closely related to spiders and scorpions than insects. Never remove a tick with your bare hand. Instead, using tweezers, grasp the tick close to the skin and pull gently.
