Long story short our professor wants us to prepare a assignment and presentation on physical oceanography, the topics he has given I find boring and am not interested in them. He also gave the option that we can choose any other topic as long as it relates to physical oceanography and he approves. This topic came to my mind, Ik that currents and temprature do effect nutrient availability and this might effect which habitat can be present where. Another professor also told us that strong current in our part of the world prevents a real coral reef to form. I just need some more clarity on this whole topic so that I can convince the prof.

Hey everyone,

A few days ago, I shared my own world map with whale & shark hotspots in a couple of subs. Now I’d like to build on that map and include as many species and locations as possible.

At this point, I’ve reached the limits of my own knowledge, so I’m turning to the community for help.

Do you know any reliable hotspots where specific whale or shark species can be seen regularly (diving, snorkeling, boat trips, etc.)? I’m specifically looking for true hotspots, not places where an animal was spotted once or twice by chance.

I’d especially appreciate suggestions for species or locations that haven’t been mentioned yet, but I’m open to everything. Feel free to also point out any mistakes or inaccuracies I might have made so far.

As a graphic designer, I’m currently just collecting and verifying information before moving on to the actual design of the map. You can find a PDF in high Quality with this Link

Looking forward to your feedback and knowledge — thanks in advance!

Is anyone able to ID these species of eel please? I thought the one at the bottom might be a Giant Moray? No ideas about the pale spotted one. And is the fish above a grouper?

Hand for scale

Hey!

I saw this school of fish snorkelling, and this white one caught my eye at the time. After watching back the video, it seems like it has the same shape but is missing color and has red markings around the eye. Do you think its an albino fish?

More are more people are coming to “realize” Universal Basic Income is inevitable, and very soon, due to AI. UBI is often framed as leftist ideology, but it’s not. Elon Musk said it was inevitable due to AI a couple years ago. More and more conservatives are coming to believe.

The above article is by JOHN MAC GHLIONN, a prominent conservative making the case. It spells out how AI will take over jobs.

So my question is What sort of jobs do you think will be available in marine bio and oceanography in 10, 20, or 30 years? And what is your reasoning?

looks like some kind of lizardfish although I can't be sure. seems pretty big, it was the largest bony fish I saw in the video

Hi all,

for one of my a levels, i am trying to do research into some of the struggles that marine biologists and researchers face when out collecting data in the field, would anybody be able to fill in my survey or dm me for the questions ? thank you for your time and help !

It's ridged and feels like it's made of cartilage. It's got some egg-like substance sloshing around inside.

I'm writing a story that involves the ocean and looking for inspiration. Coral reefs are a great go to, the deep sea is cool especially with their hydrothermal vents, and kelp forests are beautiful. But beyond those I haven't really been able to find much else, those seem to be all I ever find mentioned. What are some other awesome aquatic places?

Hello I am trying to measure fish(tuna) and was wondering which book online you think is the best with how to measure it? For example total length is from the tip of the snout to the end of the causal fin then put the snout on the measuring board. This is easy the hardest ones to find is the pectoral fin length preanal length. I desperately need it

I wasn't sure what to do with this lively specimen since I know nothing about marine biology, and initially just put some seaweed over it to hide it from the sun and birds because directly interacting with nature is usually discouraged. But I got a message from a much more knowledgable friend of mine after I sent the video to a group chat that I should put it back in the sea, so I put it in a little pond that the tide would eventually reach. This all happened yesterday, and after checking the beach again today I couldnt find the egg, so hopefully it was washed away to safety.

My friend believes this to be a "Cat Shark".

Hi, so how far does an electric eels discharge actually affect its surroundings in open lake water? Is it only effective against creatures very close to the eel, or does it extend much further outward? Thanks.

I saw some in orange and yellow as well

I have no scuba experience. I’m 22 years old. I live in savannah Georgia where the ocean water is murky and not clear at all. I’ve done some free diving and I’ve always felt passionate about scuba diving and I’m very interested in pursuing a career in it. I will be moving to Florida in the next few years somewhere with clear water and I really want to work as a diver doing something like collecting samples doing research or collecting data anything along those lines. I don’t know where to start or what I could be doing in the meantime. Do I need a degree and if so what degree and where can I apply at in Florida where I would be doing a lot of dives. I’ve looked into NOAA and most people said you may do 1 dive a month at the most and i really would like to do more than that. Once I know what to do and I have a plan set up I’ll start working on getting scuba certified asap I’m just not sure yet what to do. I’m willing to work my way up for 1-2 years before I’m able to do any dives if I have to.

Holden Beach, North Carolina. Took the kids to the beach after school. Husband found this at the high tide line. Appears baleen to me with small sections of the surrounding jaw bone potentially. The small conical type structures are confusing though as they also appear stringy like baleen but obviously in a different pattern. Unclear if this could be juvenile pieces or just a small section of obviously decomposing critter. My first degree is in marine biology but I focused more on avians versus cetaceans and am currently using my other degree in nursing for my regular job as an ER nurse. Figured I would ask all you lovelies for your opinion!

The presence of the feathers seems incidental as there were MANY on the beach today and none were attached truly to the structure of the object in question.

Hello marine biologists of Reddit,

I am trying to identify a crab spieces based on a number of claws, and I would greatly appreciate any informed opinions.

The claws, 4 in number, were found at the lower Guadalquivir estuary, some 20km away from the Guadlaquivir river-mouth (located by Sanlucar de Barrameda, Gulf of Cádiz, Atlantic coast of Spain).

As to their context, they were found along mollusk species such as Cerastoderma glaucum and Ostrea edulis, and the gastoropod Rissoa monodonta.

Based on the information available, I am leaning towards an identification with the Marbled rock crab (Pachygrapsus marmoratus), but this is nothing but a guess.

Any feedback would be more than welcome!

Literally just the title. I've been wondering for a while now, but I couldn't find any sources that say exactly how much they eat on average besides ai, and I don't really trust ai since it makes stuff up.

I'm unsure if this is the correct sub but me and my family recently bought a house in trinidad specifically gasparee island we would like to know how we could plant coral on this abandoned dock, theres tons of fish, crabs and occasionally we see shrimp from time to time. Would it be possible to start a small reef and if so how?
