HOW TO: turn fear into fascination for sharks. 🦈

Start by educating yourself about their importance and ecological role in the ocean.

Meet sharks in their own environment to experience how we can peacefully coexist with them.

Get involved—join beach cleanups or support organizations that protect sharks to grow knowledge and respect for these vital creatures.

Get connected by following marine biologists, and be inspired by their passion.

And finally, educate through media—watch documentaries like our brand-new documentary “Shark Whisperer”, our NOW on Netflix! 🌊💙

What has two types of tentacles and a red stomach? Tetrorchis erythrogaster!⁠
⁠
This small deep-sea jelly, Tetrorchis erythrogaster, is just one example of the diversity of jellies found in the deep pelagic zone.

Generally found between 400 and 1,000 meters (1,312 and 3,280 feet), this species is bioluminescent, and its red gut presumably masks the bioluminescent prey that it consumes.

These jellies have two types of tentacles—four large tentacles that extend from the bell margin and have large, yellow tips, and 16 to 24 shorter tentacles that also line the bell margin. They are often observed with their four longer tentacles extended, possibly to capture unsuspecting prey. Their bell diameter only reaches about one centimeter (half an inch).

🔊 VOLUME UP! Whale songs are more than just beautiful sounds—they could provide vital clues to our oceans’ health.

🐋 New research from Dr. John Ryan from the Research Institute reveals that hidden patterns in whale songs may be able to predict ecosystem shifts in marine environments.

By decoding whale songs, we gain insights into the health of our oceans. Let’s listen and protect.

Mysids are often called marsupial shrimps (though they are not shrimps at all) because of the pouch, where their eggs develop into juvenile tiny mysids. This is very different from true shrimps going through multiple larval stages in the open water.

Can the ocean help stop ? A startup called Equatic, which began in a research lab at , has developed technology that uses ocean water to remove CO2 pollution from the atmosphere at 99,000-times the natural rate. The technology also generates valuable hydrogen fuel as a byproduct.

Gliding through the reef with style ⚡️

Native to the Indo-Pacific region and lacking natural predators in the Atlantic Ocean, lionfish populations have surged in the Caribbean. They prey on small fish and invertebrates, disrupting marine ecosystems and harming coral reefs by depleting essential reef species 🐠

Their spread is largely due to human activity, including accidental or intentional releases from home aquariums. It is crucial never to release lionfish or other non-native species into the wild, as this can lead to severe ecological imbalances 🌎

Conservation efforts focus on targeted removal through spearfishing, lionfish hunting tournaments, and promoting their consumption as a sustainable seafood option. Public awareness campaigns and research initiatives also aim to mitigate their impact and protect marine biodiversity 🪸

Zesting up your week with the lemon jelly: Aegina citrea.🍋

The lemon jelly, Aegina citrea, is different from many other jellyfish because it has only four tentacles extending from its bell. Although jellies in the genus Aegina are relatively well known, they often surprise scientists by evolving unusual forms or colors in deep water.⁠
⁠
A surprisingly large proportion of these gelatinous marine animals have yet to be named and classified because they disintegrate when collected by traditional sampling tools like trawl nets. MBARI’s remotely operated vehicles allow us to make video observations that provide essential information about the animal’s behavior, where it lives, and what it eats. This little jellyfish has been frequently observed eating much larger comb jellies.

Coral reefs are the rainforests of the sea — vibrant, diverse ecosystems that support over 25% of all marine life 🌊🐠
They protect our coastlines from storms, provide food for millions, and are vital to the health of our oceans.
But they’re in danger — threatened by warming waters, pollution, and human activity.
Protecting coral reefs means protecting the future of our planet.
Every choice we make matters. Every action counts.

This little red jelly is Benthocodon pedunculatus, a species we often see bobbing just above the deep seafloor like little red UFOs.⁠
⁠
There are lots of little red jellies in the midnight zone, so many that it’s often difficult for researchers to tell them apart. MBARI scientists have spent years collecting and analyzing data to distinguish these species from one another based on their shape and form. In 2020, they developed a key to help scientists tell these look-alike species apart through their physical differences, depth distribution, and behavior.⁠

Strawberries are in this spring and the deep-sea is forever on trend🍓

The strawberry squid has one big eye and one small eye. Together, this unlikely pair helps the squid hunt for food in the ocean’s twilight zone. The big left eye looks upward to spot shadows cast by prey in the dimly lit waters above. The eye’s tubular shape helps collect as much downwelling light as possible. Often, this eye has a yellow lens to see through the luminescent camouflage of its prey. The squid’s right eye is small and looks downward. This eye searches for flashes of bioluminescence produced by prey or predators lurking in the darker waters below. This squid is sometimes called the cockeyed squid for the remarkable difference in size between the two eyes.

Great White Sharks are amongst us — sharing the Southern California coastline.

Despite the media continually demonizing sharks, it’s proven time and time again they’re not mindless monsters out hunting us. Yes, bites happen, but thankfully they remain incalculably rare relative to the truly countless, and harmless, interactions around the world on a daily basis. Especially considering the fact that human/shark interactions are increasing exponentially!

Sharks deserve our respect and need our protection. As a keystone species they play a crucial role in maintaining healthy oceans!

Our respect is necessary and while they’re not monsters, they’re not kittens either. That means remembering they are an apex predator and a wild animal. They should always be given space.
