The blue-ringed octopuses (genus Hapalochlaena) are three (or perhaps four) octopus species that live in tide pools and coral reefs in the Pacific and Indian Oceans, from Japan to Australia.
Contrary to popular belief, the blue-ringed octopus is not the only venomous octopus. In fact, studies have shown all octopuses are venomous. The blue-ringed, however, is the only octopus with venom powerful enough to kill a human.

A mother and calf humpback whale glide through the surface waters in Hawaiian Islands Humpback Whale National Marine Sanctuary.
After a nearly 12-month gestation period, a female humpback whale gives birth to a single calf that she closely nurtures and feeds for six to 10 more months. While humans consume milk that is about two percent fat, the milk humpback whale moms provide to their calves is 45 to 60 percent fat! This rich milk helps calves grow and develop as their mothers lead them through the first months of life.

Cloudy with a chance of Dolphins- Matthew Boettger captured GoPro footage of dolphins off the coast of Florida on a particularly glassy day. (x)
This is surreal, I love it!

Gorgeous ocean conditions, the water was especially beautiful today- perfect for Manute’a’s underwater viewing pods!
Naturalist Craig got a great shot of the Common Dolphins that came “eye to eye” to passengers in the pods.
