Sea urchins might be using their feet to see! Researchers have found that sea urchins have light receptors on their tube feet - hundreds of tiny suction-like tubes which help them to move around. Next time you are out surfing or tide pooling take a closer look at these amazing creatures - but don’t touch!
Have you heard of coral bleaching? That is what happens when corals lose their green or brown colored algae living inside of them due to environmental stress such as warmer temperatures. If conditions return to normal fairly quickly, the algae will come back; but if conditions change for too long then the coral will be permanently bleached and won’t be able to survive.
The Hōkūleʻa is a double hulled voyaging canoe built as a replica of the canoes that ancient Polynesians used to sail to Hawaiʻi. The Hōkūleʻa completed an amazing trip across the Pacific Ocean in 1976 without the use of modern instruments to and from Tahiti. Hōkūleʻa embarked on a trip around the world in June 2013 to share the importance of traditional knowledge, sustainability, and environmental conservation.
On the outside, green turtles are usually some combination of brown, black and grey in color, with yellow accents. They are called “green” turtles because their internal fat tissue is green due to their herbivorous diet.
The Hawaiʻian Islands chain found in the Pacific Ocean is the most isolated Archipelago, located approximately 2,550 miles southwest of Los Angeles and about 3,900 miles southeast of Tokyo.
Photo: NYTimes Hard corals are not the only organisms that bleach in warming ocean conditions. Anemones also host similar photosynthetic algae which convert sunlight into energy, but the relationship between the anemone and the algae can be disrupted during environmental disturbances. When anemones on a coral reef bleach, they may either recover or die if the environmental stress persists. Large anemones are best known for their relationship with clown fish, which use the anemone as a home and a safe place for their eggs. Although the clown fish don’t feed on the anemones, clown fish... (more)
