az_rabbit1

  • Rabbits have an excellent sense of smell, hearing and vision. They have nearly 360° panoramic vision, allowing them to detect predators from all directions. They can see everything behind them and only have a small blind-spot in front of their nose.
  • Rabbits have extremely strong hind limbs which allow them to leap great distances. They can jump up to one metre high and three metres long.
  • Rabbits are territorial animals who live in loosely organised social groups. They live in warrens comprising of an intricate series of underground tunnels with different entrances and exits.
  • When rabbits ‘binky’, this is an expression of joy. They will run, jump into the air, twist their body and flick their feet.
  • Rabbits are affectionate social animals who enjoy the company of other rabbits. They will perform allogrooming where two individuals will simultaneously groom each other.
  • Although typically very quiet, rabbits do communicate vocally, with varying types of vocalisations communicating different messages, e.g. low humming when running around an individual is a signal of affection.
  • Rabbits stand upright on their hind legs to give themselves a better vantage point to look for predators. They alert other rabbits to the presence of danger by thumping their hind legs.

  • Rats take care of injured and sick rats in their group.
  • Without companionship rats tend to become lonely and depressed.
  • Rats have excellent memories. Once they learn a navigation route, they won’t forget it.
  • When happy, rats have been observed to chatter or grind their teeth. This is often accompanied by vibrating eyes.
  • Rats make happy “laughter” sounds when they play.
  • Rats succumb to peer-pressure, just like humans. Brown rats are prone to disregard personal experiences in order to copy the behaviour of their peers. The urge to conform is so strong that they will even choose to eat unpalatable food if they are in the company of other rats who are eating it.
  • Although very curious animals, rats are also shy, and prefer to run away than confront a potential threat.
  • Rats are extremely clean animals, spending several hours every day grooming themselves and their group members. They are less likely than cats or dogs to catch and transmit parasites and viruses.
  • A rat can go longer than a camel without having a drink of water.
  • Rats’ tails help them to balance, communicate and regulate their body temperature.

Riboflavin    noun

Oxford Dictionary definition:  vitamin of B complex, found in liver, milk and eggs.

Our definition:  Like all the B vitamins, riboflavin (vitamin B2) plays a key role in energy production. It converts food into energy; maintains healthy hair, nails and skin; and aids mental focus and brain function.  There are plenty of plant sources, in particular greens and grains and, if you’re getting plenty of chlorophyll (ie eating lots of greens) the flora in your gut can synthesize it.  According to Victoria Boutenko in Green for Life, “To experience optimal health we need 80 to 85 percent of ‘good’ bacteria in our intestines.  Friendly bacteria manufacture many essential nutrients for our body, including vitamin K, B vitamins, numerous helpful enzymes, and other vital substances.  Such ‘good’, or aerobic, bacteria thrive in the presence of oxygen and require it for their continued growth and existence. ……. Chlorophyll carries significant amounts of oxygen with it and thus plays a critical role in supporting the aerobic bacteria.  Therefore, the more chlorophyll we consume, the better our intestinal flora and overall health will be.”  Eat more Greens! 😀

Roe    noun

Oxford Dictionary definition:  1. (also hard roe) mass of eggs in female fish.

Our definition:  Some humans like to eat fish eggs, or roe.  If the eggs come from a sturgeon the roe is called caviar.  Fishermen wait until mature female sturgeons (who are at least 10 years old) are ready to migrate upstream and lay their eggs. Once caught, the sturgeon will be transferred to a large boat, where workers slit her open and remove her eggs.

Fish farmers who raise sturgeon for caviar sometimes use a surgical procedure to remove eggs from a female without killing her. To foster reproduction in captivity, aquaculturists will induce ovulation in a female with hormone injections and then make a small incision in her abdomen. Eggs that have already detached from the ovaries can be scooped out with a plastic spoon or squeezed out into a bowl.

Most farmers use this technique only to obtain eggs for insemination, but some Russians do live-harvest eggs for food. In some cases, a farmer might perform a Caesarean on a fish that hadn’t ovulated. He could cut out some but not all of her eggs before sewing up the fish and putting her back in the water.
