> ...for suggesting sea mammals have a "gland" that filters salt from water.

No-one made any such suggestion. One person lamented that such a gland didn't exist; they did not assert its existence. The other person didn't mention glands at all.

The other person responded "sea mammals manage just fine" after I questioned how a salt gland would work in humans.

That infers sea mammals have working salt glands.

Not mammals, but some reptiles and birds do.

You are mixing up the words “infer” and “imply”. But anyhow, no the other commenter did not imply that sea mammals have extra salt glands that humans do not.

> But anyhow, no the other commenter did not imply that sea mammals have extra salt glands that humans do not.

The other commenter clearly implied 2 things:

1. sea mammals have salt glands

2. their bodies have solved the problem of removing waste salt from said glands

There's no way to interpret the commenter's statement otherwise without it being nonsensical. Sea mammals manage (what exactly) just fine?

If you can't see that, then I'm sorry, here's a simpler analogy to illustrate my point:

Me: "Pancakes can't be made without flour"

Commenter: "French chefs manage just fine"

A rational person would deduce that what Person 2 is implying is: "French chefs [are able to make pancakes without flour] just fine", not: "French chefs [are able to make pancakes] just fine"
