Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

I was wondering in my project, I would really like to know if there could be large filter feeders (like whales) of different species [cetaceans, reptiles, birds (?), fishs ...] living on a large planet (6x the earth´s size) .could this cause some sort of competition that would kill most groups quickly? or could several species occupy that specific niche without competitive exclusion?

I don’t think it would cause significant competition. Look at Earth- there are several species of filter-feeding whales, many of which have overlapping ranges. Despite this, inter-species competition doesn’t pose a real threat to their survival. If large filter-feeders were more diverse (i.e., were members of different classes), some species might go extinct, but I don’t think any entire groups would go extinct.

Well, on earth right now there are not only several species of filter-feeding whales that live side by side, but also plenty of other filter-feeding animals as well. Modern filter feeders include (sorry Beetleboy stole this list from you):
Various fish
Various sharks
Crabeater seals
Balleen whales
Manta rays

So yeah, you could have many different filter feeders on the same planet. Niches are often very flexible.

It would be preferable if you ask such questions in the questions that don't need their own topics thread in the future.
totally not British, b-baka!

I don't even really like this song that much but the title is pretty relatable sometimes, I guess.
