Reproduction

Weedy seadragons usually become mature in their second year of life when they are fully grown. The breeding season for weedy seadragons is in Australia’s early summer months. One brood is produced each season. Like their seahorse relatives, male seadragons brood the eggs. However, the eggs are incubated on the underside of the tail on a brood patch instead of in a brood pouch. The female lays 250-300 eggs that are 4 mm (0.16 in) in diameter and 7 mm (0.3 in) long. She deposits them in the skin of the male to be fertilized, covering most of the under and sides of his tail immediately behind his anus. His skin, soft at the time the eggs are first embedded, becomes hardened to form a cup around each egg to hold it securely for the 6-8 weeks incubation. Each egg receives oxygen via the cup’s blood-red tissue. The eggs are bright pink when freshly laid and darken as they develop. When hatching starts, the male releases only a few eggs at a time. He may take from hours to days to let go of the entire brood.

Fry unroll from their tight position in the egg capsule, coming out tail first. They have a very short snout, and lack leafy appendages. They settle out on the substrate in shallow water where they live off the still-attached egg capsule for about two days until their snout is more pronounced and they are ready to start hunting. They then fed on small zooplankton such as rotifers and copepods, eventually becoming large enough to hunt and eat mysid shri

<h2>Prevent of Disease</h2>

Explanation:

People in the United States can experience diseases such as heart disease, stroke, type 2 diabetes, and some forms of cancer that are associated with Ensuring an adequate intake of fruit and vegetables should further reduce risk for oral cavity, oesophagus, stomach and colorectal cancer.
Unhealthy eating and physical latency are driving reasons for death in the U.S. Undesirable eating regimen adds to around 678,000 passings every year in the U.S. because of nourishment and weight related illnesses, for example, coronary illness, malignant growth, and type 2 diabetes.
One of the best disease fighting foods is dark, leafy greens, which incorporate everything from spinach, kale, and bok choy to dark lettuces.
They are stacked with nutrients, minerals, beta-carotene, nutrient C, folate, iron, magnesium, carotenoids, phytochemicals, and cell reinforcements.
The most widely recognized hazard factors for malignant growth incorporate maturing, tobacco, sun introduction, radiation presentation, synthetic compounds and different substances, some infections and microbes, certain hormones, family ancestry of disease, liquor, less than stellar eating routine, absence of physical action, or being overweight.
Tobacco is the main source of malignant growth, however dietary components contribute altogether to certain kinds of disease.
Keeping up a solid weight will diminish the hazard for malignant growths of the throat, colorectum, bosom, endometrium and kidney.
