This is a community to share and promote marine biology research and education.

Welcome to the Marine Biology community!

For the official subreddit post about the general questions about becoming a marine biologist, internship experiences, and other resources, click here to see the post.

The objective is to create a place where every single person who cares about the sea (marine biologist or not), can share news, papers, images, opinions, ideas, questions, and everything related to this topic.

I know that being a student, nowadays, isn't a easy task, so we will try to post about internship programs, congress, and whatever possible to help us in our academic life.

For an "Other reddits you might like" section:

For identifications:

My best wishes to you all, and hope you find what you are looking for here.

Good luck!

pursuing oceanography advice

hello! sorry i know this isn’t exactly marine biology but i’m looking for some advice. i’m (18) a freshman in undergraduate majoring in oceanography and environmental science. i have a couple questions if you guys don’t mind answering. what are the fundamental principles of oceanography that I need to grasp before diving deeper into the field? what are the potential career paths in oceanography, and how can I explore them? would pursuing graduate school (or even phd) be beneficial for advancing in the field of oceanography? are there specific advantages or industries wiithin oceanography where a graduate degree is particularly valuable? how important is networking, and what are some effective ways to connect with professionals in the industry? thank you :)

Someone in Greece posted this on Facebook. What kind of fish is that? It's crazy looking! Is it edible? It looks venomous

I found this strange invertebrate while flipping rocks at my local beach. I am unsure if it is a sea sponge, or some type of coral. Let alone what species it is! Getting a positive ID would be very awesome. Found in the Eyre Peninsula, South Australia.

What species of whale might this bone have belonged to? (North Sea, England/Netherlands/France)

https://en.wikipedia.org/wiki/Franks_Casket#:~:text=The%20casket%20is%2022.9%20cm,of%20the%208th%20century%20AD.

The Frank's Casket is a really interesting piece of archaeology, from roughly 700 - 750 AD. It is supposedly made from whale's bone, according to the inscription, but (obviously) it gives no indication as to what species of whale. The casket is 22.9 cm long, 19 cm wide and 10.9 cm high. I don't need an actual answer, but I'm at least very interested in knowing what kind of whale this could *not* have been from. Thank you!

some advice and possible help for internships

hello everyone, just wanted some advice. i’m currently a first year at university and want to eventually research sharks or atleast work with them in some way whether it be conservation and whatnot. i’m aware im not going in the field as much as people would think and im fine with that. this has been a dream of mine ever since i was a child and i’ve been fully aware of the pros and cons of this job; possible low income/low funding, jobs hard to find.. (and that’s if everything works out). either way, im already putting my foot in the door by having a sort of volunteer/internship with a pretty renowned shark research who works at my school. i’ve also gotten to meet a few people in the “shark world” so far, which i think is pretty good since there isn’t many. either way, the fact that i have some sort of “experience” in my first year of college seems pretty good but i want to look at options for the summer. does anybody know any? i’ve done research but it seems more like experiences anyone could rather that actually being an intern and doing research. if you read all of this thank you!

Looking for books recommendations

Hello, I'm a biology student from Argentina (my english is not the best, i apologize for that). I've been following this subreddit for a long time, but this is my first post.

I'm looking for books that could give me a first look on how coral reefs work. I'm interested on marine ecosystems in general, but reefs caught my attention ever since I saw chasing coral.

I'll be waiting for your recommendations 👋👋

My niece is pursuing. How can I help?

Hello,

My niece is heading to college next year. She told me that she is pursuing marine biology, and I was wondering if there was anything I can do to help her out?

Any projects, research, or volunteering that I can point or towards and preferably join her, and just as an uncle/niece activity.

Any help is greatly appreciated!

Is UCSD the best option for MB?

Is UCSD the best option for MB? I’ve been trying to search for Universities in CA that support a majoring in MB. Most of them are alright, but it seems UCSD crops up the most for being the number one.

For context, I am low income, but eligible for a program that wavers my tuition if I attend a UC. I am iffy on it, mainly because of how far away it is from home (8 hours away 😭), the housing costs, and my dad being passive aggressive about my desire to attend a UC. I originally wanted to attend Manoa, but out of states are way out of my budget, and I was told about CalPoly SLO, but it still seems to fold to UCSD (and, it smells like a wharf, so I hear).

Is UCSD really that good for Marine Bio, or am I not reading the lines fine enough? Is it a worthy school?

Is there a list of all the known species of jellyfish?

I've been looking for a book or list that has a complete list of known jellyfish for a while now with no luck, just lists of 20-30 at a time and the same species on every list.

If anyone has a book title, website, or even somewhere to start looking it would be much appreciated.

What are some fish that can move on land?

Mudskippers are an obvious example, I’ve also heard of eels slithering on land like snakes. Any other examples? The concept of “amphibious fish” is so cool to me.

IUCN Red List data download

Hi all,

I’m working on a shark metabarcoding research project atm. I have my taxonomy table and would like to compare it to the IUCN Red List (preferably downloading the IUCN data and comparing both lists through a python script).

I’m sure that I’ve downloaded IUCN data before but I cannot find the option now. Anyone have any pointers? Help would be much appreciated!

Thanks 🙏

Can Jellyfish Sting Themselves?

I was Watching the live Jellyfish camera at the Monterey Bay on Youtube. As I was watching I just wondered, can a jeelyfish sting itself with its nematocysts since they are triggered mechanically by touch. Can they sting other Jellies and are each of them immune to the venom of their own species or others?

Why do fish make oil?

I was curious about this and tried to research this on google but the only things I can find are mostly health benefits of fish oil for humans. The one slightly useful thing I've found are some studies on how pelagic fish tend to have more oil, and that it can be a useful tracker of food chains as certain oils are only made by algae.

There does seem to be a distinction between "oily fish" and "white fish", with oily fish having oil in their flesh while white fish only having it in their liver? Not sure how scientific that is though.

Does anyone here know why some fish would have that much oil? If it's just an energy storage thing, why would they do that instead of processing it to subcutaneous fat? (which they do seem to have?)

This is going to bother me for a while if not so any pointers or search terms would be helpful

Book(s) recommendation please.

Could I please have some book titles that have names, pictures, and details of microorganisms found in freshwater aquariums. I would like very much to learn about what I am viewing under my microscope. Thanks
