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.

PLoS ONE 12(1): e0169281. doi:10.1371/journal.pone.0169281 Aquaculture is one of the fastest growing industries in the world. A 2014 report by the UN-FAO estimated global freshwater and marine farming to constitute 44% of all […]
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!
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!
Marine Protected Areas (MPAs) are a popular conservation tool and are in many situations very effective. Unfortunately, as with many plans, there may be some unintended consequences, as seen in the case of small MPAs in Fiji, where they appear to have attracted corallivorous crown-of-thorns sea stars (Acanthaster spp.).

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.
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.
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.

Sperm whales are very large, but they can still be tricky to find in the ocean! These researchers combined several data sets, from centuries old whaling records to modern automated location recording, to determine the locations off the southwest Australia most suitable for sperm whales, so policy makers can plan to protect these animals and other scientists can save time searching for them.
Invasive species are widely talked about as unequivocally bad influences on ecosystems, but oftentimes their interactions are more complex. Click here to read more about an unexpected interplay between two mussel species in the intertidal zone!
Well, it’s that time of year again where hoards of costumed kids roam the streets in search of candy. While these kids are met at each door with smiles and sugar, older kids and teenagers are more likely to be met with disapproving frowns – aren’t they too old to be doing this? Well, if you’re a decorator crab you also like to go all out in costume, but it’s not the younger crabs that are doing it, decorator crabs have to be a certain age before they start dressing up!
Scientists have been doing a lot of work recently trying to figure out how species are going to react to climate change. This research group wanted to figure out just how much heat seahorses could take…and seeing as they can’t get out of the ocean, things aren’t looking good. Read on!
Fish are not typically thought of as the most intelligent animals. Yet, new research on manta rays may revolutionize the way we think about how some fish grasp difficult concepts like self-awareness. Read on to see how.
Animals move for a number of reasons. The French grunt leaves the coral reefs at night for seagrass. A group of scientists proposes and provides good evidence for why they might do that! Read on to discover whether they’re leaving to avoid being parasitized?
As any gambler will tell you, the higher the financial risk, the larger the potential reward. As it turns out, the hungrier we get, the higher risks we’re willing to take, and this characteristic transfers over to other members of the animal kingdom. In this study, we look at how cuttlefish make decisions about attacking prey based on their level of hunger and the risk they are willing to accept when the reward is that much sweeter.
We all know dolphins are intelligent creatures that communicate with one another, but a recent study has analyzed dolphin sounds finding evidence of actual human-like, structured conversation. Their chats are full of complex sounds and frequencies, akin to words and sentences. In addition, dolphins appear to have a politeness edge on humans as they were observed to pause and hear out others, rather than interrupting with their own sounds!
Tiny jellyfish live, swim, and eat in a viscous environment. How they capture their food is something of a mystery. A University of Oregon group took advantage of several fancy imaging techniques to shed some light on the matter.
Whales aren’t the only animals hydrophones can detect out in the ocean. In fact, in the near future it might be possible to listen in on animals like scallops and determine if they’re healthy or not. Intrigued? Click here for more!
In the deep sea off the coast of Antartica, sea urchins are getting crafty to avoid predation from king crabs. In the face of global climate change, their tactic may become less effective while the predators become more abundant. Find out more here.
