Adult seahorses eat 30 to 50 times a day if food is available; due to their slow consumption they must feed constantly to survive. [20] Big-belly seahorses do not have a stomach or teeth, so they feed by sucking small invertebrates in through their bony tubular snouts with a flick of their head. Their snouts can expand if the prey is larger ...
The histological structure of their intestine is similar to that of seahorse species that also lack a stomach (agastric teleosts) such as the H. abdomnialis and the H. guttulatus. Thus, these species may have split from each other from a common ancestor, but more than just morphological data would be needed to confirm this observation. [11]
Seahorses range in size from 1.5 to 35 cm (0.6 to 13.8 in). [13] They are named for their equine appearance, with bent necks and long snouted heads and a distinctive trunk and tail. Although they are bony fish, they do not have scales, but rather thin skin stretched over a series of bony plates, which are arranged in rings throughout their bodies.
Short snouted seahorses are considered ovoviviparous meaning that the female deposits eggs into a pouch on the males stomach, called a brood pouch, and the male goes through pregnancy and labour. [9] Sexual maturation occurs during the first reproductive season after birth.
People with the gene have about an 80 percent chance of developing diffuse stomach cancer. Women with the gene have about a 60 percent risk for developing lobular breast cancer.
When mating, the female seahorse deposits up to 1,500 (average of 100 to 1,000) eggs in the male's pouch, located on the ventral abdomen at the base of the tail. Male juveniles develop pouches when they are 5–7 months old. The male carries the eggs for 9 to 45 days until the seahorses emerge fully developed, but very small.
The lined seahorse (Hippocampus erectus), northern seahorse or spotted seahorse, is a species of fish that belongs to the family Syngnathidae. [ 3 ] [ 4 ] H. erectus is a diurnal species with an approximate length of 15 cm (5.9 inches) and lifespan of one to four years.
How long does it take to rehydrate after stomach flu? Full recovery from dehydration may take a few days, depending on how much fluid was lost. Most people will show improvement within a few hours ...
