Sea turtle hatchlings are in a world of danger as soon as they attempt to make their way from their nesting site on the sand to the ocean, where they will find food and eventually meet a mate, they face predators at every turn. The ocean isn't much kinder than the beach, as fish attack the baby turtles, and pollution and fishing nets threaten their survival as they grow.
Cuttlefish and their colorblind cousins, squid and octopus, see aspects of light, including polarized light, that are invisible to humans
Cephalopods are sensitive to the linear polarization characteristics of light. To examine if this polarization sensitivity plays a role in the predatory behaviour of cuttlefish, scientists from the University of Bristol examined the preference of cuttlefish Sepia officinalis when presented with fish whose polarization reflection was greatly reduced versus fish whose polarization reflection was not affected.
Learning to dive involves learning a new set of skills. Mask clearing, buoyancy control, regulator recovery and all the other skills that you learn on an open water course are essential for dealing with the underwater world. As a diver progresses through diving they learn additional skills such as using a drysuit, wreck diving or how to rescue their buddy. With technical diving there are again some new skills that need to be learnt.
The vessel rests at a depth of 80 meters and appears to be free of mud. According to some reports, it was carrying mixed cargo including steel products and as many as 1,000 bottles of cognac and 300 bottles of liqueur.
Raumanmeren Hylky-Team is a group of divers and wreck hunters who primarily search for shipwrecks in the Baltic sunk by German submarines during the First World War of which they have located around 20.
The divers say the vessel has remained quite intact. They will decide whether to try to raise the contents after closer examination.
