What is a fish’s favorite color? Raising fish in certain colors of tanks can cause stress, aggression, or undesirable color patterns. The best color for raising fish varies by species and life stage, but some groups follow general patterns.

Did you know fish prefer certain colors? When they don’t like the color of their tank, the fish may get stressed or aggressive! #aquaculture

Dogs have a rebellious teenage phase just like humans The first evidence of dogs going through emotional changes during puberty has been discovered. They are more likely to disobey orders from their dog-parents and be more difficult to train. Behavior does improve after puberty when dogs reach 12 months of age.

Just like humans, dogs can act like rebellious teens during puberty. They may even be too busy with their ‘ruff’ life to listen to dog-parents! #dogparents #dogsoftwitter #animals

Muscles lost in our adult primate ancestors still appear in humans A review of previous anatomy studies found that some “ancient” muscles that are normally present in other primate species may be more common in humans than previously thought

Hey, pet owners, are you quarantining your cat or dog? Chinese researchers studied which animals are at risk of becoming infected with the coronavirus and if they can pass it on to others. They discovered that at high levels of exposure, cats and ferrets were more likely to become infected with the novel coronavirus. However, dogs showed no evidence of COVID-19 symptoms or viral carriers.

How would we know if COVID-19 came from a lab? A group of researchers gathered evidence from previous studies and, using what is known about the virus structure, made the case that the 2019 novel coronavirus was unlikely to have been intentionally engineered.

Scotty is the oldest and biggest T. rex ever found A tyranosaurus rex's unearthed fossils reveals a fairly complete set of bones including a hips, limbs, and a complete skull, allowing scientists to get better measurements than ever before.

The one of the largest land predators to have ever lived, the mighty Tyrannosaurus rex, just crowned a new king. On March 21st, a team of University of Alberta scientists described the oldest and largest T. rex ever found. Scotty’s unearthed fossils reveals a fairly complete set of bones including a hips, limbs, and a complete skull, but for a complete, set paleontologists still had to use what they knew about T. rex anatomy to fill in the blanks.

New Sex Chromosomes Created After Decades Long Experiment Hybrid swordtail fish may reveal secrets about how new chromosomes and species form

Sexually reproducing animals have their sex determined through many mechanisms. Sex in reptiles such as alligators is determined by egg temperature during incubation. Some species, like the clownfish, can be hermaphroditic, shifting from one gender to another depending on the environmental READ MORE

We must go deeper: Submerging net cages for healthier fish Submerging fish farms may be better for fish, but how can it be done for fish that also need air?

Most fish farming in the ocean uses net cages that float because it is easier to feed and remove fish at the surface and because some fish species require access to air. However, the surface of the ocean experiences a READ MORE
