Female, male and juvenile big-bellied seahorses make "click" sounds while feeding, often paired with a head movement called a "snick". Females click more frequently than males, suggesting a possible link to sexual selection. Click frequency is correlated with body condition, indicating that these sounds may provide clues about the seahorse’s ...
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, and the male often ...
The males do not have to compete with other males, and female anemone fish are typically larger. When a female dies a juvenile (male) anemone fish moves in, and "the resident male then turns into a female and reproductive advantages of the large female–small male combination continue". [22] In other fishes sex changes are reversible.
The male parent of a horse, a stallion, is commonly known as the sire and the female parent, the mare, is called the dam. [1] Both are genetically important, as each parent genes can be existent with a 50% probability in the foal. Contrary to popular misuse, "colt" refers to a young male horse only; "filly" is a young female.
This image shows the prehensile tail utilized in reproduction by the male seahorse. Like all species of seahorses, the lined seahorse reproduces sexually, laying eggs every season. In addition, the male is the parent that looks after the newborn seahorses. The reproduction process begins at the initiation of the courtship process.
The evolutionary benefit to this phenomenon is that a male can fertilize multiple females. [6] The male may be reinvigorated repeatedly for successful insemination of multiple females. [7] This type of mating system can be referred to as polygyny, where one male has multiple female mates, but each female mates with only one or a few males. [5]
A hinny is a domestic equine hybrid, the offspring of a male horse (a stallion) and a female donkey (a jenny). It is the reciprocal cross to the more common mule, which is the product of a male donkey (a jack) and a female horse (a mare).
The greater redhorse is the largest fish in its genus, averaging around 46 cm (18 in) and 2 kg (4.4 lb), and reaching a maximum size of 80 cm (31.5 in) and 5.9 kg (13 lb). This species of fish has small eye sockets in contrast to their large rounded skull.
