Except that in cangaroos the mother actually needs to be pregnant and birth its babies first. In sea horses the female directly lays the eggs inside the pouch of the male, impregnating it, and the male then undergoes pregnancy. So actually very different to kangaroos?

  My point was that it is nothing like in kangaroos. The comparison is just misleading.

    It’s like kangaroos in the sence the it’s a pouch not a uterus. Some fish put eggs in a cave, but that doesn’t make the cave pregnant.

    Pregnancy has been traditionally defined as the period of time eggs are incubated in the body after the egg-sperm union.[1] Although the term often refers to placental mammals, it has also been used in the titles of many international, peer-reviewed, scientific articles on fish, e.g. Consistent with this definition, there are several modes of reproduction in fish, providing different amounts of parental care

    Going off of this, it’s just a matter of the term “pregnancy” being co-opted to describe something completely different from what it means in its original context. As does happen, even in science.
