Serious Science: Comparing Fish Life Cycles

Comparing the fish life cycles of various species that share the same body of water helps biologists understand the bigger picture of the whole ecosystem.

Want to explore the underwater world of some interesting fish? That's easy! Just watch this video. Then you can learn even more in your classroom with a combination of watching the video and taking part in the fun free Lesson Guide that really dives into the underwater science of understanding fish species. Just download the free Lesson Activity at the bottom of this page to get going.

If you've ever fished in a certain river or a lake, you probably found out that it's home to some very different species of fish. Right? Then it kinda makes you wonder how the life cycles compare between some different fish species that both share the same body of water as their home.

But first, consider this. Fish, humans, birds, and all living organisms go through a “life cycle”.  This life cycle begins at birth and lasts until they reach reproductive maturity. Within that life cycle, the organism typically goes through a number of physical changes. They can also have a yearly cycle of various activities or behaviors within their life cycle. Similar organisms that share the same ecosystem can have very different life cycles.
