Actually no. The nurturing of young is only present strongly in animals with k-type reproductive strategies.. mostly mammals, birds, reptiles, etc. K-type meaning they have long gestation periods, produce few offspring with high survivability rates and invest a lot of time and care of them.
The other type of reproductive strategy is r-type, which fish and all invertebrates use. R-type is basically having short gestation periods, producing a ton of offspring with low survivability rates and invest little to no care in them.
Generally speaking, organisms that are larger and have more complex physiology tend to be k-type reproducers and ones that are smaller and have simpler physiologies tend to be r-type.
You getting your chick pregnant, her producing only a few kids, taking 9 months each time, yall feeding, clothing, teaching, and paying for them for 18 years=k-type
A scorpion spitting out 100 babies and letting them ride her back for a few days and rejecting them or even eating them if they fall off=r-type.
But there's many organisms that put in less work than a scorpion and literally do nothing for their offspring. Like many marine animals, oysters or whatever just release them in the water and that's it.
