Rules of Science Facts:
Post titles must contain a fact!
Submissions must be verifiable. Please link directly to a reliable source that supports every claim in your post title or if your post is a photo leave a source in the comments. Images alone do not count as valid references. Videos are fine so long as they come from reputable sources as well (e.g. Discovery, Scientific American, BBC, etc).
News articles are fine as long as they are of actual scientific topics and contain verifiable material. No pseudoscience.
No Clickbait Titles. If the news article you are linking sounds like clickbait, then please change it to reflect what the study actually was and not what the news author has molded it into. Clickbait will be removed. No titles with unnecessary Caps, that's click baity.
Please flair your link! If it looks like we don't have an appropriate flair option message the mods.
No misleading claims. Posts that omit essential information, or present unrelated facts in a way that suggest a connection will be removed.
All NSFW links must be tagged.
All posts must be made using Metric units.
Don't be a dick!
No post titles asking for upvotes or approval.
Your source cannot be a blog or non scientific news site (e.g. no Live Science, some kid's website on frogs, your family's website on what you find interesting, etc.).
If you make a scientific claim in the comments you must back it up with a source or the comment will be removed. It's easy to fall into anecdotal comments, but we're trying to keep this sub factual.
Joke responses, comments that add nothing to the post or are not on topic, or obvious trolling will be removed without warning. This is a sub for facts and discussion. Repeat offenders will be banned.
Leave your circle jerking at the door. Any circle jerk or Unidan/Jackdaw nonsense will result in a temporary ban. There are many scientists on Reddit, they are not all Unidan, please be respectful.

In order to prevent impaling each other, the first striped marlin (Kajikia audax) in a hunting pack will flash its stripes before moving in to grab fish. The next marlin in line will then move forward and repeat the process. The display only occurs during hunting.

On average, eastern cottontails will have 3-4 litters a year, with 3-8 offspring per litter. While they generally start breeding at one year, some are ready as early as 2-3 months old. In just 5 years a single pair of eastern cottontails can have 350,000 descendants!

Tunicates belong to phylum Urochordata, which is closely related to phylum Chordata - which includes all of the vertebrates! That means these little goo balls are more closely related to vertebrates, like us, than they are to most other invertebrates.

The hindwings and abdomen of the death's-head hawkmoth resemble a queen honeybee. They use this disguise to raid hives to steal honey. The disguise is not only visual, they also make some sounds and odors to deceive the bees.
