The Amazing Sea Horse Life Cycle

Sea Horse Life Cycle

From page 28 of "Sea Horse, run!" ©2011 by Tammy Carter Bronson

The sea horse has an amazing life cycle that begins with the courtship dance. Once the courtship is complete, the female fills the male’s brood pouch with eggs. Baby sea horses grow in the male’s brood pouch, and as you can see in my illustration above, the male sea horse gives birth. Depending on the species, one birth can produce about 1,500 babies. What a fascinating fish!

Fun Facts About Sea Horses


Sea horses are classified in the family Syngnathidae (pronounced sin-NATH-ih-dee). Every animal in this family is a fish. Syngnathdae is Greek for ‘fused jaws’ because the mouths of fish in this family do not open or close. About 330 species of Syngnathidae have been classified. Thirty-seven of these species are sea horses, three are sea dragons (Leafy, Weedy, and Ribboned), and the rest are pipehorses or pipefishes.*

Where do sea horses live?
Most sea horses live in shallow ocean water near land. Sea horses may be found in estuaries, mangrove swamps, sea grass meadows, or reefs around the world.

Why do sea horses hide?
Larger fish like tuna or red snapper eat sea horses. Sea turtles, sting rays, sharks and even penguins munch on sea horses, too. Sea horses hide from these predators by changing color to match their environment.

How do sea horses move?
Sea horses move slowly by means of fins that beat as fast as 70 times per second! The dorsal fin propels the sea horse forwards. Sea horses have two, small pectoral fins (one behind each gill) that allow the sea horse to hover or change direction.

What do sea horses eat?
Sea horses do not have teeth, so they swallow their food whole. Sea horses suck food into their long, narrow snout, but the food must be tiny to fit through their mouth. Sea horses eat zooplankton, little shrimp, and the larvae of fish, crab, or worms. Sea horses do not have stomachs either. Without a stomach, sea horses cannot digest food well, so they have to eat large amounts in order to survive. Sea horses may eat for up to 10 hours per day, and they may swallow 50 to 300 tiny animals per hour!

What is the largest sea horse?
The Big-Bellied Sea Horse (Hippocampus abdominalis) is the largest species. These sea horses may reach fourteen inches in length!

What is the smallest sea horse?
Hippocampus denise is a pygmy sea horse that measures about half an inch in length.

Name That Fish Activity


All of my fish in “Sea Horse, run!” are drawn with graphite pencil then painted with watercolor, but my fish are not drawn to scale which means their sizes are not true to life. Some appear smaller or larger than the real fish. See if you can match the fish in the picture with name below.

How to play:

Draw a line from the letter to the name of the fish, or write the letter next to the name of the fish, or fill in the blanks.

Weedy Sea Dragons

Weedy Sea Dragons are widespread along Australia’s southern coast from Sydney on the east coast to the Perth region in the west. They are especially abundant in shallow, weedy areas, but “Weedies” have even been found as far south as the southern tip of Tasmania. Their color and leafy appendages vary depending on their environment and diet. Weedies can grow to one and a half feet in length, and specimens in captivity can live well over ten years.

The mating season for the Weedy Sea Dragon begins around October or November which is Spring in Australia. Following an elaborate mating dance, a female will lay her eggs on the underside of the male’s tail. The male Weedy carries 250 to 300 eggs under his tail, and the eggs hatch in about two months. The following BBC video shows the mating ritual of a pair of Weedies in their natural habitat.

Weedies are almost fully grown after one year. If the tanks are deep enough, this species will breed in captivity; as a result, Weedies are becoming more common in aquariums. Most specimens found in aquariums were tank-raised in Victoria. Wild adults do not adapt well to captivity and are likely to die after capture, whereas young, tank-raised specimens easily survive transport.

Sea dragons are classified in the family Syngnathidae (pronounced sin-NATH-ih-dee). Every animal in this family is a fish. Syngnathdae is Greek for “fused jaws” because the mouths of fish in this family do not open or close. About 330 species of Syngnathidae have been classified. At least thirty-seven species are sea horses, three species are sea dragons (leafy, weedy and ribboned), and the rest are pipehorses or pipefishes.

The vast array of brilliant colors (red, yellow, orange, blue, violet) combined with the lines and dots often exhibited by this species make the Weedy Sea Dragon a candidate for the “Rainbow Serpent,” one of the most revered ancestral spirits of Aboriginal folklore.

My latest video demonstrates how I created my character, Ribbon, for “Sea Horse, run!”. It takes 6 minutes to view, but it’s worth it. You’ll see real ribboned sea dragons at the Minnesota Aquarium as well as the step-by-step process I use to draw, paint, cut out, and design a character for the book. As an added bonus, I’ll show you exactly where I hid Ribbon on every page in the story.

Ribbon is a ribboned sea dragon. Specimens are usually greenish-yellow like the sea grasses they hide in. Ribboned sea dragons are found in waters northwest of Australia. They can grow to be about one foot in length. Ribboned sea dragons are more tropical than their southern relatives, the leafy and weedy sea dragons.

Butterfly Fish

Butterfly Fish like to swim in pairs.

Several people have asked how I selected the fish for “Sea Horse, run!”. With thousands of fish species to choose from, I had to narrow my options. In the beginning I found the choices overwhelming, then I decided to pick fish named for animals in my previous books. In Tiny Snail the reader meets Mr. Squirrel and Miss Butterfly, so I chose a squirrel fish and butterfly fish.

In my third picture book, Polliwog’s best friend is Perch. I chose two different perch for “Sea Horse, run!”: the pearl perch and gurnard perch. Since Polliwog is about a tadpole who doesn’t know she’s turning into a frog, I had to include a frog fish, too!

Pipefish are related to sea horses and sea dragons, and pipefish are the most abundant fish found in the sea horse family, Syngnathidae, meaning ‘fish with fused jaws.’ I saw the Moorish idol in several aquariums, and the sea anemones in the story needed a few clown fish for company. Plus many children can easily identify both the Moorish idol and clown fish because they are prominent characters in the classic Pixar film, Finding Nemo.

So far, most of the fish I chose for the book swim alone or in small schools, but coral reefs are home to great numbers of fish that swim in large schools. I needed at least one schooling fish that moved in large numbers, and I chose the pomfret.

Pomfret FishThere are many species of pomfrets that live in oceans around the world. The largest pomfret species lives in the Atlantic Ocean, but my pomfrets are from the eastern coast of Australia. In real life this Australian pomfret is a tiny fish only one inch in length, but my pomfrets look much larger.

Additional bony fish in “Sea Horse, run!” include the sea horse, leafy sea dragon, weedy sea dragon, ribboned sea dragon, and eel. The shark is also a fish, but sharks are not a ‘bony fish’ because they do not have bones.
