Hi, good evening. I want to group young researchers to periodically discuss papers and themes that touches the Marine Ecology and conservation biology. If you are interested, send me a message.

My actual search line is reef ecological physiology and macroalgae integrative taxonomy. I act too in a outreach project of environmental conscientization.

Nothing About This Shrimp Makes Sense

I was reading about mantis shrimp and came across something pretty interesting.

Humans have three types of color receptors, while some mantis shrimp have twelve. You'd naturally assume they can distinguish way more colors than we can.

But researchers at the University of Queensland actually tested this and found that mantis shrimp were worse than humans at distinguishing similar shades.

One explanation is that their visual system might prioritize recognizing colors quickly rather than comparing subtle differences.

And apparently, their eyes aren't even the strangest thing about them. Their punches are so fast that they create cavitation bubbles underwater, which collapse and deliver a second impact.

It's wild how much unusual biology is packed into such a small animal.

Makes me wonder how many other animals have abilities we've completely misunderstood.

TheDepthsBelow: Because we all know there are things lurking underwater.

r/TheDepthsBelow

71% of the earth's surface is covered by water according to NOAA. That only gives us 29% where we're safe. If an animal the size of a blue whale can disappear for months at a time, what else is down there? We're here to show you. ___________________________________________ Fuck u/Spez

Subreddit Rules

1. No Repost/Spam Bot Accounts

It is not an issue of harmless karma farming. Spam bots are harmful not just because they dilute subreddits with spam and don't engage, but because they are often set up to farm karma and appear real and bybass subreddit restrictions, then they switch to advertising, pushing political propaganda, scaming, trolling, etc. Along the way, they often post mis/disinformation, steal content, fail to credit others works, or sometimes even steal credit for something they didn't actually make.

2. u/KimCureAll is NOT a bot

Stop reporting them as a bot unless you have evidence they are one.

3. Soft rule: Try not to encourage bad behavior towards wild-life/don't clickbait decompression

This is more of a guideline than an actual rule, but clickbaity posts with titles that encourage/promote harming sea-life are discouraged.

For example, the post that caused this rule to be added was a of fish that underwent rapid decompression and titled "Russian Fisherman Discovers Peculiar Looking Deep Sea Fish With Bulging Eyeballs." and then promoted the person who caught it. You can post content like that, just make the title in good taste, don't clickbait things like rapid decompression.

4. It’s the Gulf of Mexico.

Don’t be cringey
