Seahorses are an exceptional species in the vast ocean realm. With their head and neck resembling that of horses, they have earned the name seahorses or walruses. These incredible creatures are capable of adjusting their body color to blend with their surroundings, which results in them exhibiting a wide range of colors. Get ready to discover some fascinating facts about seahorses!

Exploring the Enigmatic Abode of Seahorses

Seahorses are, without a doubt, a one-of-a-kind species in the deep blue sea. These creatures have heads and necks that resemble that of horses, which is the reason why they are referred to as seahorses or walruses. Interestingly, they have the ability to alter their body color based on their surroundings, resulting in an astonishing array of colors. So, let’s find out some fascinating facts about these charming creatures!

What's Mysterious About the Seahorse's Body?

The seahorse is a unique creature with many mysterious features. Unlike what we might imagine, they do not have scales, but spines on their bodies. They also lack a stomach and teeth, so food quickly enters and exits their digestive system, leading to constant eating. Seahorses have excellent eyesight, with each eye able to operate independently. These creatures move by flapping a small fin on their back at a speed of about 35 beats per second and use their pectoral fins as rudders. Their tail is also special, as it can wrap around small plants to keep them from being swept away by water.

Growth and Development of Seahorses

The evolution of seahorses is quite unique as male seahorses carry the developing embryos in their pouches, unlike most other species where females assume this role. When it’s time for mating, the female deposits her eggs into the sac and the male fertilizes them. The embryos then develop for approximately two weeks before being released into the marine environment, where they happily swim about and discover the vast ocean world.

The process of seahorse pregnancy

The fascinating process of seahorse pregnancy involves the fertilization of eggs, which are embedded into the sac wall and surrounded by a spongy tissue. Interestingly, male seahorses provide these eggs with prolactin, a hormone that is typically responsible for milk production in mammals. The incubation bags play a crucial role in providing the developing embryo with oxygen and a regulated environment. While the egg yolk provides necessary nutrients to the embryo, male seahorses also contribute nutrients, such as energy-rich lipids and calcium, to build the baby seahorse’s skeletal system. These nutrients are secreted into the incubation bag and absorbed by the embryo. Additionally, the incubation bag offers immune protection, osmosis, gas exchange, and waste transport. Finally, the eggs hatch in the pouch, which regulates water salinity and prepares the baby seahorses for life in the sea. The gestation period varies between two to four weeks, depending on the seahorse species.

Number of seahorses after birth

The average number of seahorse offspring per mating ranges from 100-1000, but can vary depending on the species. Smaller species may have as few as 5 offspring, while larger species can have up to 2,500. Male seahorses are responsible for giving birth to their young, which they do through abdominal contractions at night. By the next morning, the male is ready to mate again. Unlike some other fish species, seahorses do not nurse their young after birth. The baby seahorses are vulnerable to predators, ocean currents, and harsh temperatures that can endanger their delicate bodies. Only less than 0.5% of baby seahorses survive into adulthood, though this survival rate is relatively high compared to other fish species.

Habitat of Seahorses

Seahorses are commonly found in various tropical and temperate waters across the globe, but are most common in seagrass beds located in Southeast Asia, South Africa, and the Panama Canal.

Status of the Seahorse Ecosystem

The current state of the seahorse ecosystem is concerning as these adorable creatures are now considered endangered in the World Red Book. To protect them, the International Convention on Trade in Endangered Species of Wild Fauna and Flora CITES has banned their trade and exchange. Even in Vietnam, there has been a noticeable decline in the number of seahorses, which is alarming for the health of the ecosystem.

Why are seahorses becoming fewer and fewer?

What is causing the decline in seahorse populations? One major factor is the hunting and trading of seahorses in various regions. In traditional Chinese and Vietnamese medicine, seahorses are commonly used to treat bone, joint, and physiological ailments. Additionally, seahorses are often captured and kept in aquariums where they typically only survive for about six weeks before quickly perishing. Unlike other marine species, seahorses are especially vulnerable to environmental pollutants and disruptions to their food sources due to their limited swimming abilities. The destruction of their natural habitats, such as coral reefs, seagrass beds, and mangrove swamps, is also a contributing factor to the decline in seahorse populations. These habitats are steadily disappearing due to pollution, mining activities, and climate change, leaving seahorses with little refuge. As a result, seahorse populations are at risk of disappearance as they are easily fragmented.
