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.

POPS'Dinosaur eel' could inspire future armour i thought I'd include a picture of a euryptarid, also known as a sea scorpion, which was one of their predators, and one of the largest known arthropods that has existed at 6ft 7in. Makes you glad they're extinct...as far as we know.

POPSWelcome to the Honeybee Hemolymph Proteomics Database at the University of British Columbia.
The honeybee, Apis mellifera, is an invaluable partner in agriculture around the world, both for its production of honey and, more importantly, for its role in pollination. Honeybees are largely unexplored at the molecular level, despite a long and distinguished career as a model organism for understanding social behavior. Like other eusocial insects, honeybees can be divided into several castes: the queen (fertile female), workers (sterile females) and drones (males). Each caste has different energy and metabolic requirements and each differs in its susceptibility to pathogens, many of which have evolved to take advantage of the close social network inside a colony. Hemolymph, arthropods' equivalent to blood, distributes nutrients throughout the bee and the immune components contained within it form one of the primary lines of defense against invading microorganisms. In this study we have applied qualitative and quantitative proteomics to gain a better understanding of honeybee hemoly
