Where does a leafy seadragon live?
Leafy seadragons are marine fishes that are found below the low tide in the depths of 3.3-54.7 yd (3-50 m). They reside in and around the marine flora and vegetation under the sea.
This species of fish is found only in the temperate waters of the southern and western coastline of Australia. They are found in the stretch of Kangaroo Island, south Australia to Rottnest Island in western Australia.
What is a leafy seadragon's habitat?
A leafy seadragon’s habitat is on the seagrass meadows, algae, kelp growth on rocks, seaweed beds, and rocky reefs under the sea.
Who do leafy seadragons live with?
In the late winters and onset of spring, leafy seadragons migrate to shallow waters from deep bays in congregations to mate. During winters, they move alone and migrate deep into the ocean.
How long does a leafy seadragon live?
Leafy seadragons attain sexual maturity at two years of age and probably live up to 10 years.
How do they reproduce?
Among seadragons and seahorses, males of the species carry the young ones to birth. Female leafy seadragons produce up to 250 bright pink eggs.
They deposit the eggs onto a male leafy seadragon’s tail with the help of a long tube, called an ovipositor. The eggs are attached to a special brood patch beneath the tail of the male seadragon, where the eggs are fertilized.
The leafy seadragon enables the hatching of eggs by shaking its tail and rubbing it against the rock and seaweed.
After about nine weeks, the eggs start to hatch depending on the conditions of water. The colors of the ripe eggs could be purple or orange.
The male leafy seadragon pumps his tail to let young ones be born. The process takes about 24 to 48 hours. The seadragon does not release all the eggs from the brood patch together.
That is why the process takes hours and days to complete. After the young ones are born, they are independent to move and hunt. They have a small yolk sack appendaged to them externally.
The sack provides them food and nourishment for the next few days. The sack acts as a safety net for the young and juvenile leafy seadragons.
During the season of breeding, male leafy seadragons hatch two batches of eggs. Since the chance of young leafy seadragons getting hunted by predators is high, only 5% of the eggs eventually survive. They attain sexual maturity after two years.
What is their conservation status?
The IUCN has updated leafy seadragons as Least Concern on conservation status in its Red List of Threatened Species. It was listed as Near Threatened before that due to its declining population.
