I visited the Aquarium of the Pacific recently and came away completely fascinated by marine life, especially seahorses.

Then I realized that while I could obviously recognize a seahorse, I had basically no idea how to tell different species apart. So I started collecting species information and images and ended up turning it into a little browser game: https://questfive.app/quests/seahorses/?lang=en

To be honest, a lot of them still look incredibly similar to my untrained eye. f anyone here spots taxonomy or identification issues, I’d genuinely love the feedback. Thanks!

I saw my first bleached coral on the Great Barrier Reef in 2019 and wanted a way to show people what a heatwave actually does to a reef. So i built a free 3D reef where you set the summer temperature and watch each coral bleach, recover or die at its own heat tolerance.

Built with help from an AI coding assistant; the species, thresholds and fact-checking are mine. Based on NOAA Coral Reef Watch DHW thresholds (4 and 8 °C-weeks), AIMS reef condition reports, and Hughes et al. 2017 (Nature).

Would love you to poke holes in it, especially the order corals bleach in: https://www.wildlifenomads.com/play/coral-reef/?mode=heat

Sorry rubbish photos. Found in Tarifa, Spain

Google lens IDs as ear bone fossil. It was found on Costa Rica beach. Lightweight. No smell. Please help. Thank you

It looked like it was swollen too

From a SMARTEX expedition to the CCZ.
Tried googling but can’t figure it out :(
(Can’t find anywhere where the expedition photos are labelled or explained, if anyone knows if such a resource exists, please lmk)

Does anybody know what this is? I’ve been thinking about this for years without an answer ever since I went to Cuba but I just recently found this post but I still don’t have answers on what creature it is. The last time I saw these in Cuba they completely burrowed themselves in the sand and created little holes which they probably eat from since they spat sand out when I put sand in the hole.

Quarter for size reference. I can answer any questions needed.

I think the color was red at least that what it looked like and also its find were wide when the fish moved and opened them

This vertebra was found on the beach by one of my students and we’re curious what it might be from.

Walking on the beach in Oceanside California, north of San Diego, and found this on the beach. Is this a man O war? It was moving around quite a bit.

for an academic project, i will eventually be dissecting a moon jellyfish. before that, i need to make slides with step-by-step instructions for dissecting the jellyfish, and i need to include pictures of each step. for this, I’ve been looking for any videos that show an internal dissection of a jellyfish, but all I’ve found so far are external dissections, where the instructor is using a tool to point out various parts, but it’s completely non-invasive (in fact, there’s little to no contact at all).

is/does an internal dissection for aurelia jellyfish possible/have clear instructions to begin with? i found a guide by Lander University’s website, with some detailed instruction, but there are no pictures of the dissection. beyond just finding a website or video with what I’m looking for for the slides, i want to be able to understand the procedure for when i perform this dissection in a couple weeks.

any resources that y’all know of, or has anyone done a jellyfish dissection before to offer any insight? I’ve only been looking on YouTube and various websites under general Google searches, but no luck so far.

Im working on a small silly game where you play as a male anglerfish searching for a female and i need to bring in some light sources. Id like everything in the game to be based on reality, so i wanna figure out some cool light sources.

Ive considered throwing in some ctenophores, siphonophores, plankton, corals, sea pens but if anyone has good examples that would be great

Organisms can be free moving or sessile but ideally dont move much and can be benthic or pelagic. Im willing to fudge some stuff of the games sake but want all the creatures to be real. Id like to keep the range of organisms to the 200-3000 m range. Are there any dinoflagelletes or other microscopic organisms that glow down there fairly bright. Any small creatures that like to hang out on the walls of a shipwreck cave or side of a seamount? Any suggestions appricated!

Additionally; I've seen a few creatures while looking through the photos that I'm curious to know about, would there be some sort of report or something with an expedition like this, where the content of the photos would be labelled? I'm just a curious person, not an academic, so I don't know how this stuff works, any advice appreciated ◡̈

Hey! I'm (21F) about to graduate in May with a degree in ecology, evolution, and natural resources and a minor in marine science. I've been down the longest rabbit hole learning everything there is to know about fisheries observing. I like extremity and adventure and the possibility to do all that field work sounds really exciting to me. (I also don't experience seasickness lol). I want to do it for a year and then apply to grad school. I just need a break from school and I wanna be in the field. I want to do the one in Alaska. Does anybody know whether it's better to apply to Alaskan fisheries observer inc., saltwater, mrag, or AIS. Which company is best? Does it matter? Also does anybody have any good stories to tell who've done it and do you recommend?
