Sea sponges

  Sea sponges are used in drugs for treating asthma and cancer.

»   Llamas are smaller than horses, making them good pack animals, but they are not strong enough for people to ride upon. Typically, a llama can carry 80 to 100 pounds.

»   Sea sponges, stationary invertebrates that sometimes form a tough, flexible skeleton full of pores, were harvested as the first sponges used for bathing and cleaning.

»   Lobsters molt 20 to 30 times before reaching the one-pound market size.

»   Seabirds have salt-excreting organs above their eyes which enable them to drink salty water;seasnakes have a similar filter at the base of their tongue.

»   Lobsters, like grasshoppers — feel no pain. They have a decentralized nervous system with no cerebral cortex, which in humans is where a reaction to painful stimuli proceeds.

»   Seals and whales keep warm in the icy polar water thanks to a layer of fat called blubber under their skin. Whale blubber can reach up to 20 inches (50 centimeters) thick.

»   Lone Pine Koala Sanctuary opened in 1927 in Brisbane, Australia, and it was the first, and is still the largest, koala sanctuary in the world. Tourists can cuddle one of 130 koalas, hand feed kangaroos and emus, and see a large variety of Australian native wildlife in the 50-acre sanctuary, such as wombats, Tasmanian devils, and dingoes. Koala cuddling has been banned in New South Wales since 1997, but cuddling is still permitted in Queensland, and especially at Lone Pine Koala Sanctuary. In Queensland, koalas can only be cuddled for less than 30 minutes per day. They must also get every fourth day off. At Lone Pine, koalas are timed for “clock on” and “clock off” when they go to the koala cuddling area.
