Ever seen a dolphin that looks like a flying slug? That’s the Northern right whale dolphin. They are easily recognizable by their sleek, streamlined body and lack of a dorsal fin. They are found in the deep, cold-to-warm temperate waters of the Pacific Ocean.

Are seabirds ocean savers? New research published in Nature Reviews Biodiversity finds seabirds help connect ocean ecosystems by moving nutrients from open ocean to islands and back to coastal waters. Learn more: https://www.earth.com/news/how-saving-seabirds-could-help-save-the-oceans/

North Atlantic right whales are nearing extinction. Ship strikes, entanglement, and impacts of climate change threaten their survival. But now, researchers think that human-made noise in the ocean may be having an effect too. Learn more: www.theglobeandmail.com/podcasts/the...

A decade-long study by @oceannetworks.ca and @uvic.ca found no sign of the bone-devouring “zombie worm” Osedax on sunken whale remains — a disappearance that may signal deep-ocean oxygen loss and ecosystem collapse Learn more: news.uvic.ca/media-releas...

We often think of sea turtles as gentle ocean wanderers, but the inside of a leatherback’s mouth tells a different story. 😳 It’s lined with specialized, cartilage-like protrusions called papillae. These help trap slippery prey, such as jellyfish, so they can be swallowed.

Just in time for Halloween, scientists have uncovered a spooky new species: Chondrocladia sp. nov., a carnivorous sponge ominously dubbed the “death-ball,” a predator with hook-like traps. Learn more: oceanographicmagazine.com/news/carnivo...
