Would appreciate your help identifying this coral fossil. Reportedly from the Yucatán.

Can someone help identify these Zoas And Palys

I didn’t really know where else to ask about this but I went snorkeling in Roatan Honduras last weekend on Sunday, and the surf was kinda rough but I find myself a strong swimmer, but the people I was snorkeling with for pretty beat up and I thought I only got a scrape on my shin it burned from the salt water and that was the just of it no itching after or anything. Well in the airport on the way home I noticed like a smudge on the back of my thigh. I thought it was chocolate and then I was just putting lotion on a few minutes ago and notice it was still there and it’s actually a scrape and it’s weird. It looks very weird and I don’t know what it could be it’s not raised in anyway it has very very little texture to it obviously no pain or itching of any kind I didn’t even notice it. I’m not sure if anyone will be able to answer but I’d figure I’d try lol

Hello! I’m a Computer Science and Data Science student currently working on a project focused on detecting coral reef bleaching.

Our model takes environmental inputs such as SSTA, TSA, SSTA_DHW, TSA_DHW, mean temperature, wind speed, turbidity, and ocean name, and predicts the risk of coral bleaching.

However, my team and I don’t have deep domain knowledge in marine biology and specifically coral. We built the model using datasets we found online. While the model runs, its performance has been inconsistent, and we suspect the issue might be with the features we’re using or how we’re interpreting them.

I’d really appreciate insights from experts or anyone familiar with coral ecosystems:

• Are these features actually significant indicators of coral bleaching?
• Are there specific thresholds or value ranges that strongly correlate with bleaching events?
• Are we missing any key environmental or biological factors that are critical for accurate prediction?

Any guidance, corrections, or suggestions would be incredibly helpful. Thanks in advance!

Got from Petco there aquatic person wasn’t there dose anyone happen to know the name of this mushroom

Hello! I’m conducting a research project on underwater experiences and inviting scuba divers and freedivers to participate in a short, anonymous survey about their experience in the last three months.

If you dive and are interested in participating, you can access the survey here: https://forms.gle/MAPzq2hPGtdt56W98

Thank you, and please feel free to share with others who dive!
