The alligator pipefish is a unique type of fish. It is also called the double-ended pipefish. Its scientific name is Syngnathoides biaculeatus. This fish belongs to the pipefish family, called Syngnathidae. It is the only species in its group, Syngnathoides.
You can find alligator pipefish in warm, shallow waters. They live in the Indian and Pacific Oceans, from East Africa to northern Australia. These fish love to hide in seagrass beds and seaweed. They often stand straight up, head down, to blend in with the plants. This makes them very hard to spot! Their long, thin bodies can grow up to 29 centimeters (about 11 inches) long. They eat by sucking up small creatures.

About the Alligator Pipefish
The alligator pipefish can grow to about 29 centimeters (11 inches) long. But most of them are around 20 centimeters (8 inches). Their heads are narrow, and their snouts have two small feelers. Their bodies are long and shaped like a triangle.
What It Looks Like
The alligator pipefish has a dorsal fin on its back. This fin has 38 to 48 soft rays. It also has small anal fins with 4 soft rays. Its tail is long and gets thinner towards the end. This tail can grab onto plants, helping the fish stay in place. It does not have a tail fin.
The color of this fish usually matches its home. It can be green, brown, or gray. Female pipefish often have spots. They might also have a white zigzag line on their belly.
Where Alligator Pipefish Live
Alligator pipefish live in warm parts of the Indian and Pacific Oceans. You can find them from South Africa and the Red Sea to India, Japan, and Australia. They also live near Indonesia, the Philippines, and New Guinea. In Australia, they are found from Geraldton in Western Australia to Batemans Bay in New South Wales.
Their Home Environment
These fish prefer calm waters. They live in lagoons and on coral reefs. You can also find them in bays and river mouths. They love areas with seagrass meadows and floating algae. They usually stay in shallow water, less than 5 meters (16 feet) deep.
How Alligator Pipefish Behave
The alligator pipefish is not a very good swimmer. It moves by wiggling its small fins on its chest and back. It eats tiny animals like zooplankton and small creatures that live on the seafloor. It sucks them into its mouth. Their diet includes small shrimp, tiny crustaceans, and other small bottom-dwelling animals. They also eat very small fish.
Family Life
Male and female alligator pipefish look a bit different. Males are usually larger than females. Males become ready to have babies when they are about 18 centimeters (7 inches) long.
In some places, like Moreton Bay, Australia, they have babies in the summer. But in Papua New Guinea, they can breed all year round. A female pipefish lays between 60 and 200 eggs. The male then carries these eggs in a special pouch on his belly. The eggs stay there until they hatch. It seems that one male and one female often stay together. All the eggs in the male's pouch are usually at the same stage of growth. This suggests they came from the same female.
Conservation Status
The alligator pipefish is sometimes dried and used in traditional Chinese medicine. It is called "hailong" in this use. These fish are also sold as pets for home aquariums. Public aquariums also keep and raise them.
Why We Need More Information
Scientists do not know if the number of alligator pipefish is going up or down. The International Union for Conservation of Nature (IUCN) is a group that checks on animals. They do not know where the fish sold for trade come from. It is unclear if they are caught in the wild. We also do not know if people fish for them on purpose. Sometimes, they might be caught by accident. Or, they might be raised in special farms.
Because of this lack of information, the IUCN says the alligator pipefish is "data deficient". This means they do not have enough facts to decide if the fish is safe or at risk. In Australia, it is listed as a protected marine species under a law called the Environment Protection and Biodiversity Conservation Act 1999.
