Fish Life Cycle for Kids

Fish go through an incredible transformation from miniscule eggs to the amazing underwater creatures we know and love! Let’s take a quick swim through the different stages of a fish’s life cycle:

Eggs: The adventure begins with adult fish releasing tiny eggs, often in large groups. These eggs are fertilized and protected by a sticky coating until they’re ready to hatch.

Larvae: When the eggs hatch, out come the larvae! These tiny fish are almost transparent and have a yolk sac attached, providing them with essential nutrients until they can find food on their own.

Fry: As the larvae grow, their yolk sac disappears, and they become fry. Fry are little fish that still look quite different from their parents. They start swimming around and hunting for tiny food particles in the water.

Juvenile Fish: As they continue to grow and develop, the fry gradually transform into juvenile fish. They start to take on the physical characteristics of their adult counterparts, like fins and scales.

Adult Fish: Finally, after reaching a certain size and age, the juvenile fish become full-grown adults. They are now able to reproduce and carry on the life cycle, ensuring the continuation of their fishy population!

Before using these free preschool printables, teach your preschool some fun facts about fish. You can use one or more of the books I’ve shared below, or you can just share these interesting tidbits:

  • There are over 30,000 species of fish.
  • Jellyfish and starfish are not really fish.
  • Fish have nostrils, but they breathe with their gills.

Preparing the Pages

To use these worksheets with your preschoolers, all you’ve got to do is print them out. They are ready for use immediately. No prep work is required! However, you can make the activities reusable by laminating them and using velcro dots on the cut/paste pages.

Life Cycle Vocabulary

There are three activities included in this activity pack. The first page is a life cycle of a fish mini-book. I suggest printing this page on regular printer paper. Have students write the correct vocabulary word on the line in each box (seed, sprout, etc.)

You may need to write the vocabulary words on a notecard or post it for kids to look at as they write the words. Cut apart the pages and staple them to create a mini book if you’d like.

Not only does this page reinforce vocabulary words associated with the life cycle of a fish, but it’s a great way to introduce or reinforce the sight words I, see, and a.

Life Cycle Sequencing

The next activity in this pack is a sequencing activity. One sheet is a numbered sequence mat. The other is a set of four sequence cards. Print these two pages on regular printer paper. You can use colored printer paper if your kids don’t enjoy coloring.

Now, have your kids cut out the sequencing cards. This is a great way to strengthen preschoolers’ fine motor skills by using scissors to cut out the cards. Glue the cards in the correct order on the sequencing mat.

If you’d like to make this activity reusable, you can laminate the cards and the mat. Add a velcro dot to each box and to the back of each card.

Finally, there is a one-page sequencing activity. Kids can color the life cycle pictures, or you can print the page on colored paper. Have kids cut out the numbers at the bottom of the page. This is another opportunity for them to practice their scissor skills.

Or, you could build other fine motor muscles by letting them use a ½” circle punch to cut out the numbers. Have them glue the numbers beside the appropriate image to sequence the life cycle of a fish.
