- The species has been spotted 2,500 miles (4,000 kilometers) up the Amazon River in South America and dwell in Lake Nicaragua, a freshwater lake in Central America. Bull sharks have traveled up the Mississippi River as far north as Illinois and are regularly spotted in India's Ganges.
- But bull sharks have special physiological adaptations that enable them to live in fresh water. Their kidneys recycle the salt within their bodies and special glands, located near their tails, also aid in salt retention.

Anatomically Correct - Learn

Here you can "virtually" dissect a cat, view labeled diagrams, or even see live dissections to expand your knowledge on cat anatomy. Select a learning activity on the right to begin your lesson! Later you can test your knowledge by taking online quizzes in the test yourself portion of this site (accessible on the toolbar at the top).

Science Centric | News | How Volvox got its groove

- Ancestors of Volvox algae made the transition from being a single-celled organism to becoming a multicellular colony at least 200 million years ago, during the Triassic Period.
- Cooperating successfully is the key, Herron said
- 11 more annotations...
- - All the macroscopic organisms we see around us trace back to unicellular ancestors,' said Herron, a doctoral candidate in the UA's department of ecology and evolutionary biology. 'Each of those groups had to go through a transition like this one
  - We think the early changes in this process were related to cooperation among cells and conflicts among cells - and finally to the resolution of those conflicts,' he said.
  - University of Wisconsin in Madison
  - Volvox and its relatives live in freshwater ponds all over the world. Some of the species are unicellular, while others live in colonies of up to 50,000 cells.
  - The most complex species have a division of labour - some cells do the swimming, others do the reproducing.
  - One of the earliest traits to evolve is the clear jelly-like substance visible between the cells of the spherical Volvox colonies, Herron said. 'We think that stuff is what held the earliest multicellular colonies together.'
  - Banding together in a larger mass can provide protection from predators, he said. 'Some things can't eat you if you're bigger.'
  - But producing the goo, called extracellular matrix, takes resources and is one of the costs of cooperation.
  - So now there's a temptation to cheat,' Herron said. 'Let's say I'm in a four-cell colony. I'm going to let the other three guys make the extracellular matrix, and I'm going to focus on growing and reproducing. That's the conflict.'
  - Overcoming that conflict is essential to becoming a multicellular organism, he said. The benefits of cheating have to be reduced for the cells to cooperate successfully.
  - Some traits the team studied are genetic traits that mediate conflict.
    
    Genetic control of cell number is one of those, he said. 'If my number of offspring is fixed at four, now there's no reason for me to cheat. I can't have eight offspring when everyone else is having only four.'

In this companion Web site to the NOVA program The Four-Winged Dinosaur, read an article by producer Mark Davis on his long-standing interest in the debate over whether birds evolved from dinosaurs or not, view a slide show of fossils from organisms that lived alongside the four-winged dinosaur known as Microraptor, compare the anatomy of the oldest known bird to its dinosaur cousins, and test-fly a Microraptor model in a virtual wind-tunnel." />
