Science and History


white-tailed eagle.

This half inch long sea spider is an amazing form of life. It has no lungs or gills, transmitting gasses directly through it's slender exoskeleton. The digestive tract extends down it's legs and is clearly visible here as snaky, colored tubes inside the transparent exoskeleton. This specimen is on fire coral in 30 feet of water in Grand Cayman. Sea Spiders are found in all oceans and at least one species can get up to 2 feet long in some deep sea areas.
