The deep ocean is vast and full of neat ocean dwellers, many of which scientists know little about. One way to investigate them is from images and videos captured during deep-sea exploration efforts using submersibles. A group of scientists did just that to quantify the benthic assemblages at different depths and a variety of substate types on a ridge in the Indian Ocean.
The use of tools by animals has been documented in a wide range of species, from birds to invertebrates, encompassing land animals and marine animals. Animals use tools to help shelter themselves as well as find their next meal. By investigating animals on a genetic level it’s possible to determine whether tool use is specific to a population and how long ago this ability evolved. Recently, scientists investigated the genetics of a fan favorite, the sea otter, to try and pinpoint how long they’ve been using tools and what they’ve been using them for. Read on to find out more!
Brain size might dictate the laws of attraction in guppies.
Although its easy to mistake a sponge for a furry looking rock, these invertebrates and the microbes that inhabit them have some surprising chemical abilities.
We aren’t going to need a bigger boat to prevent shark attacks…read this review article to get an idea what shark attack prevention strategies are best for both humans and sharks!
Age estimations of marine mammals are traditionally made with a single tooth. A group of scientists from Australia think they can improve the traditionally method by adding more teeth into the equation.
As the Earth warms, sea ice declines. What happens to those animals who rely on the ice? Today’s oceanbites looks at one animal, the ringed seal, and how it may be affected by climate change!
Because of their ability to conduct photosynthesis, most of our planet’s oxygen comes from microscopic organisms in the ocean called algae. In addition to photosynthesis, some of these algae can also hunt and consume prey to supplement their energy needs. In this study a group of scientists has set out to determine just how their hunting strategy works, and why each strategy has its own set benefits and drawbacks.
Why do northern and southern populations of Atlantic cod have different haemoglobin subtypes? A recent study upsets over 50 years of theory.
Scientists have found an alarming accumulation of certain persistent organic pollutants in an environment previously thought pristine and untouched by humans: the deep sea.
Chemistry is important for a lot of things, but can it change the behavior of animals? Read on to find out how changes in water chemistry alter the behavior of a venomous cone snail!
After migrating thousands of miles from their southern wintering grounds, males of a certain species of shorebird log thousands more miles scouring the summer territories for fertile females. It’s pretty nuts.
Glaciers get a lot of attention because they’re expansive sheets of ice. They’re important to understand because they can impact sea level, circulation, climate, albedo, and they are homes to microbial organisms and large animals. A new reason they are getting attention is their recently realized importance to the global silica budget. Researchers found that melting glaciers deliver enough silica to the surface ocean that their contribution should not be ignored.
Global temperatures are increasing at a rate never before seen in Earth’s history. Although efforts to mitigate this are still very important, it is also important to study and understand what is going to happen to the plants and animals that live here. Evidence of climate change already surrounds us, and the more we know, the better prepared we will be to cope with our new environment. In this study, a group of researchers have studied how two species of clams react to a warmer environment to understand the coping mechanisms they use for survival.
Killer whales, or orcas (Orcinus orca), are amazingly intelligent and social animals. What can they tell us about the evolution of menopause?
While watching a pod of killer whales attacking their prey, scientists noticed a small group of humpback whales come to the rescue. Why did these humpbacks risk their own safety to save another animal? Read more about how scientists are investigating this question.
Most of the time coral reef communities are discussed, it seems the focus is whether they’re dominated by hard coral or algae. It turns out there may be other possible outcomes for reefs in the future. Find out more in today’s oceanbites!
Many scientific studies have shown that kelp species are sensitive and vulnerable to climate change. Some scientists think of them as sentinel species, or early warning indicators of climate change. Recently, a large mass of warm water, affectionately known as “The Blob,” covered the northeast Pacific, resulting in a long-term elevation of ocean temperature. With existing ecological records of kelp forests in California, this provided an opportunity for researchers to test whether these giant kelps are indeed a sentinel species and can warn us about the looming effects of climate change.
Excerpt: We’re taught at a young age that all food comes from the sun via photosynthesis. But, does it really? Read on to find out about a major fishery that is underpinned by chemosynthetic primary production!
