Although females could technically mate with several males, seahorses form strict monogamous pair bonds for an entire season at least, a rare sight in fish species. [9] Female seahorses remain faithful during the pregnancy by returning to the male's territory each day for an early morning greeting.
Seahorse life-cycle. The male seahorse is equipped with a brood pouch on the ventral, or front-facing, side of the tail. When mating, the female seahorse deposits up to 1,500 eggs in the male's pouch. The male carries the eggs for 9 to 45 days until the seahorses emerge fully developed, but very small. The young are then released into the water ...
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.
As many as 250 babies can be released during the delivery.
Pregnant male seahorse. Male pregnancy is the incubation of one or more embryos or fetuses by organisms of the male sex in some species. Most species that reproduce by sexual reproduction are heterogamous—females producing larger gametes and males producing smaller gametes ().
The second behaviour is wrestling. This occurs when one male refuses to release the opposing male from his hold. Both males will fall with their interlocked tail but the submissive male will darken and flatten in a submissive position until it is released. [9] Male and female pairs of short snouted seahorses are very faithful to each other.
H. whitei is an ovoviviparous species, with females using an ovipositor to transfer eggs into a male's brood pouch, where they are fertilized and protected until the male gives birth to live young. [1] Males may brood 100–250 embryos at a time, and after a three-week gestation period, give birth to about 150 young. Males brood several times a ...
Male kangaroos bulk up the same way humans do, through diet and exercise. Not only do the males gain strength from playful sparring matches, but they also engage in other muscle-building exercises.
