Honestly, it would probably be terrifing if you knew all about amphipods aswell as everything else!

I just came from a post you had commented on about blenny breeding, and I'm just so impressed! Thank you for all the info youve given on this site!
Haha, thank you - I've still got plenty to learn!
Actually, if you dont mind me asking, is there a specific website that you could reccomend for learning more about any sort of marine stuff? I was looking at the MBIsite but that isnt opening for me. Seeing indentification/research/projects with inverts and fish is just so interesting!
There are a bunch, but which I would recommend depends on what you want to accomplish - is there anything in particular you're hoping to learn?
Yeah, the MBIsite has some great info on it, but it's old now, and I don't know how much longer it'll be operational for (hopefully a long time, but given that it doesn't have info from beyond 2014, I'm not very optimistic about it).
For just general research stuff, Google search (not Google Scholar Search) is your friend as it can help you find links on the following sites (assuming no special academic/research access and that you want to avoid paywalls as much as possible):
-Research Gate
-Academia.edu (you need a free account to read the stuff)
-JSTOR (you need a free account to read the stuff - they've got a lot of older stuff, but I've found some of the older stuff is really good/contains a lot of detail)
These next ones are good (sometimes really good) but more likely (sometimes very likely) to have paywalls or require access to an article through an institution - sometimes you can still get free articles or good info from just the abstract they show on the page, but other times you can't:
-PubMed
-Springer
-Elsevier
-ScienceDirect
-Tandfonline
-BioMedCentral
-Springer
-Frontiers
-Academic.oup
-Nature
-MDPI
-SciELO - Brazil
And this definitely doesn't cover every site out there - these are just some of the more common ones that pop up for me.
For info on fish/inverts (profiles on each), the list below is pretty good (again, definitely not complete - a notable one I know is missing is Inverts.WallaWalla.edu):
Yeah, none are perfect by any means, but here are some that are generally pretty good (I'm sure I'm forgetting a few; I left a few that are unlikely to be relevant or just don't contain much info out on purpose):
-LiveAquaria (hobbyist oriented)
-Saltcorner (hobbyist oriented)
-JungleDragon
-FishBase/SeaLifeBase
-Fishes of Australia (Museums Victoria)
-Mexican Fish
-Florida Museum of Natural History
-Indian River Lagoon Species Inventory
-Shorefishes (Smithsonian Tropical Research Institute)
-Seaunseen
-WildSingapore
-Kwajalein Underwater
-NCFishes (rarely pops up, but good for some species found on the Eastern US north of Florida)
-INPN (it's French, but comes in handy sometimes)
-Frogfish.ch (frogfish specific, but by far the best frogfish technical info site around)
Edit: New I'd forgotten a few:
-MarineBio (Marine Conservation Society)
-Reef Life Survey
-The Online Guide to the Animals of Trinidad and Tobago (I'm not sure if you can purposefully search through these files on their site somehow, but it comes up pretty often with Google searches - it's species profiles compiled by The University of the West Indies at St. Augustine, Trinidad, and Tobago)
-Eprints@CMFRI (similar to the above, I can't get it to let me search their library on their site, but it comes up pretty often with Google searches - there are a number of species profiles compiled by the Open Access Institutional Repository of Central Marine Fisheries Research Institute)
And some more in the link below:
Does anyone know a good website or place that has a really nice selection of fish or just information about fish. I seem to constantly find new fish and never know the names. LiveAquaria has a okay selection but they are still missing some fish. Just looking for info with pictures and names...
