Sharkcano, a melting pot for biology

No, a Sharkcano is not a volcano that erupts sharks. IT IS WAY COOLER THAN THAT! It is a submarine volcano that hosts a diverse macro community in water that is much warmer and more acidic that the surrounding seawater.

Do You Have Your Exit Buddy?

It’s a tough ocean out there for a larval fish—sticking together can be the best thing to do. But until now, we didn’t know how beneficial schooling could be. Intrigued? Click here to find out more!

Killer whale pods: hunting dynamics

Killer whale pods spend almost all of their time together, with the exception of when they hunt. Why are they not social when they hunt? Could it be to ensure the survival of the newest and weakest pod members? Is it related to food availability? It is related to food preference? It is just a factor of physical abilities? Read more to find out what scientist have learned so far!

Cool Fact! Octopuses spawn with ease when temperatures are lower

Octopuses in the YP may experience temperature changes that do not bode well for reproduction. At what point will the influence of temperature be enough to inhibit the octopus population from growing? Consequences could be tough for octopus fisheries in the area. Read about how temperature stress that a mother experiences can influence her offsprings ability to cope.

Parenthood: The Most Rewarding Experience or The Ultimate Sacrifice?

Our human parents make a lot of sacrifices for us! They devote their time and energy, provide for us, invest in us (monetarily, sure, but also emotionally), nurture us, attempt to teach us, make career decisions with us in mind, and lose a lot of sleep worrying about us. However, in the marine world things can get much more extreme? Some animals make the ultimate sacrifice by literally dying to reproduce. Find out more about some of these marine creatures in today’s Oceanbites!

Why Mom Cares.

Does mom care? If you are a skink from the wrong neighborhood she might, otherwise, you are on your own kid. Read about the evolution of paternal care traits in one skink population that is not observed in the others!

Warming up to climate change

Are you a fish that can’t cope with warming oceans? Don’t hesitate, acclimate! Scientists have found if fish have the chance to acclimate to warmer temperatures they may be better off in the future.

Mercury at elevated levels observed in only some elephant seals, but why?

Mercury: we know it from old-school thermometers and we know if from sushi; and now we know that the distribution in the ocean is reflected in the blood of northern elephant seals. N.B. No elephant seals were harmed during this research.

The Sting of Sex: odd mating adaptations of box jellyfish

It might be hard for a box jellyfish to buy into the old adage “sex sells,” especially when their gonads are laced with stinging cells. This is just one bizarre adaptation in these organisms, read on to find out more!

What is the source of organic molecules in Von Damm vent fluids?

The origin of life is with out a doubt a fascinating topic of discussion and debate, intensified by the fact that there is no definitive answer (yet). A group of WHOI scientists present a mechanism and environment where organic compounds can be formed from inorganic ones via abiotic production. The plausibility of their suggestion is strengthened by the present day occurrence of said mechanisms in hot spreading centers where ocean plates are formed at the bottom of the ocean.

Sea urchins work harder, faster to cope with ocean acidification

The ability of sea urchins to withstand ocean acidification comes at a hidden cost.

A head of their time: how invertebrates had it in them all along to form the vertebrate head

We owe our hard heads to our invertebrate ancestors.
