POPSSea Slug Is Half Plant & Half Animal The article continues to say that baby slugs can't carry out photosynthesis until they eat their first & only meal of algae. ""We collect them and we keep them in aquaria for months," Pierce told LiveScience. "As long as we shine a light on them for 12 hours a day, they can survive ." Pierce and his colleagues used a radioactive tracer to ensure that the slugs are now producing the chlorophyll themselves and not gathering it from algal contamination." PS Sorry about the extraneous bits in this clip.

POPSSea Slugs Photos I find these creatures quite amazing, just love the assortment of their colours and shapes.

POPSSolar-powered sea slug harnesses stolen plant genes But a mystery remained. Chloroplasts only contain enough DNA to encode about 10% of the proteins needed to keep themselves running. The other necessary genes are found in the algae's nuclear DNA. "So the question has always been, how do they continue to function in an animal cell missing all of these proteins," says Rumpho.

POPSSolar-powered sea slug harnesses stolen plant genes In another surprising development, the researchers found the algal gene in E. chlorotica's sex cells, meaning the ability to maintain functional chloroplasts could be passed to the next generation. The researchers believe many more photosynthesis genes are acquired by E. chlorotica from their food, but still need to understand how the plant genes are activated inside sea-slug cells.

POPSResearch and no simple answers to Climate change The flow on effects to fisheries and emissions from desalination plants may be counter productive with out a proper look a long term effects on the environmental impacts from what a first might seem a sensible solution to in end have been self defeating waste of taxpayer dollars.

POPSFossils tell of mass exodus from sea Creatures could develop some protection from the sun in the water, but the land was wide open, and predators were yet to get anywhere the efficiency of ocean based predators. They can understand why shelled arthropods had the protection to survive, but can't understand the survival of soft bodied things like worms and Molluscs? then perhaps they can explain why a slug like creature evolved a shell and branched unto the Snail genotype. i don't imagine life is safe anywhere for exposed slugs and worms, and solar radiation, particularly UV Light can accelerate development. and change. Perhaps they were moving to the place that was the least dangerous.
