Squirt here to talk about fish!
There are five stages in the life cycle of a fish. Fish begin as an egg, just like you did. Then as the fish grows and develops, it become larval fish. During this stage the fish lives off of a yolk sac. The larval stage of a fish is similar to the human fetal stage when you were growing inside your mom. Take a look at this anglerfish in the larval stage.
When a fish starts eating on its own it enters the fry stage. In humans this would be the child stage. As a fry continues to develop it then enters the juvenile stage. During the juvenile stage, the fish matures reproductively. Humans undergo this stage during their teenage years. The last stage of development in fish in the adult stage. In the adult stage, fish are capable of reproducing to create their own offspring (or children). Humans also have an adult stage, for example your mom and dad are adults.
Just like human boys and girls are different, so are many fish! This is known as sexual dimorphism where the different genders (or sexes) look different. Male anglerfish are much smaller than female fish. Also, only female anglerfish have the bioluminescent lure. Check out the images below!
