Kiki’s story

This week our video of Kiki Bosch freediving in 2 degree glacial water in Iceland has reached millions. If you enjoyed the video I encourage you to turn on audio and have a listen to her story. Kiki has been training for cold exposure and believes that by disturbing the comfort in our everyday lives we can reconnect to our senses and nature.

 

Kiki’s dream is to freedive in the Arctic. This August we have been offered a unique opportunity to join a sailing vessel in The Arctic. During this two week expedition we want to continue filming Kiki’s journey, produce educational videos and communicate scientific research. But we need your help to make this happen. If you want to support Kiki and Ocean Imaging please click here visit out Patreon.

During our filming we have been astounded by the number of people that have been helped by the cold. If you are interested in learning more about the benefits of cold exposure and experience the beauty of Iceland, Kiki will be running a workshop in Iceland in October.

How cephalopods see colour

Researchers from the UC Berkeley and Harvard University propose “colourblind” cephalopods may be able to see colour after all!

The father and son team Alexander and Christopher Stubbs, suggest octopus and cuttlefish use their large, wide pupils to accentuate the refraction of different wavelengths of light. They may be able to sense colour by bringing certain wavelengths into focus on the retina.

Sea lion facts

Sea lions can hold their breath for up to 20 minutes. Unlike dolphins, sea lions exhale before diving. Their nostrils have special muscles to open them in order to breathe.

Sea lions can dive to depths over 250m, these animals have a high tolerance for carbon dioxide.The oxygen in their body concentrates in their heart and central nervous system rather than in non-vital organs. Their relative, the elephant seal, can hold its breath for 62 minutes and dive to depths over 1200m

Starfish communication

Scientists have “cracked the code” of crown-of-thorns starfish communication.

For the first time, we are able to better understand the critical importance of the chemical communication that drives crown-of-thorns behaviour, providing excellent leads in the development of biocontrol technologies.

The paper ‘The crown-of-thorns starfish genome as a guide for biocontrol of this coral reef pest’ appeared online last month in the journal Nature. Click here to learn more:
