Amazing Facts about Jellyfish

1. Jellyfish first appeared about 650 million years ago and are found in every ocean, from the surface to the deep sea. Some are also found in fresh water

2. A group of jellyfish is called a bloom or swarm

3. Jellyfish do not have a respiratory system since their skin is thin enough that the body is oxygenated by diffusion

4. Jellyfish do not have a brain or central nervous system, but rather have a loose network of nerves, located in the epidermis, which is called a “nerve net.”

5. Jellyfish are composed of more than 90% water. Most of their umbrella mass is a gelatinous material (the jelly) called mesoglea, which is surrounded by two layers of cells which forms the umbrella (top surface). The subumbrella (bottom surface) of the body is known as the bell

6. Jellyfish are dioecious; that is, they are either male or female. In most cases, to reproduce, both males and females release sperm and eggs into the surrounding water, where the (unprotected) eggs are fertilized and mature into new organisms

7. Box jellyfish venom is the most deadly in the animal kingdon and has caused at least 5,568 recorded deaths since 1954. Each tentacle has about 500,000 sindasites which are harpoon shaped needles that inject venom into the victim

8. The lion’s mane jellyfish is the largest known species of jellyfish. The Arctic Lion’s mane jellyfish is one of the longest known animals and the largest recorded specimen had a bell (body) with a diameter of 2.3 m (7 feet 6 inches) and the tentacles reached 36.5 m (120 feet). It was found washed up on the shore of Massachusetts Bay in 1870

 Hyndora africana is one of the most bizarre-looking plants on the African continent and absolutely not the most common of plants to be encountered in the veld on any casual hike. 

 

 Rafflesia arnoldii

 The flower with the world's largest bloom is the Rafflesia arnoldii. This unusual flower is found in the rainforests of Indonesia. It can grow to be 3 feet across and weigh up to 15 pounds! It is a parasitic plant, with no visible leaves, roots, or stem. It bonds itself to a host plant to obtain water and nutrients. When in bloom, the Rafflesia eliminates a repulsive odor, similar to that of rotting meat. This odor attracts insects that pollinate the plant.  

 

 Dracunculus vulgaris

 A dashing, good looking plant but don't stand too close when the flower is set for pollination.

 

 Wolffia angusta

 Wolffia angusta, the tiny green specks growing between Spirodela polyrhiza and Azolla filiculoides.Wolffia angusta is one of the smallest flowering plants in the world. 

 

 Wollemia nobilis

 

 This bizarre-looking tree was recognized only from 120 million-year-old fossil leaves before 1994; fewer than one hundred exist in the wild. They have unusual bark that looks like bubbles of chocolate, multiple trunks, and ferny-looking leaves growing in curves. They can grow up to 125 feet high.

  

 Welwitschia mirabilis

 

This sensuous plant can live up to 1,500 years and is only situated in a strip of land in the Namibia Desert comprising part of Namibia and Angola. It can survive on moisture from fog and dew.It consists of 2 leaves that grow continuously, a stem base and roots. It is thought to be a relic from the Jurassic Period.
