The seahorse, which belongs to the family Syngnathidae and genus Hippocampus, is a fascinating and distinct fish species found in the ocean. It is classified under the phylum Chordata, subphylum Vertebrata, class Osteichthyes, and order Gasterosteiformes. Interestingly, its name comes from "hippos" meaning horse and "campus" meaning monster in Greek.

The seahorse derives its name from its horse-like head and curled tail, in addition to possessing distinctive characteristics such as a long snout and mobile eyes. These adaptations aid in the species' survival underwater. An intriguing aspect of seahorses is the male's responsibility for carrying offspring, setting them apart from other creatures, which has led to their popularity as pets.

Seahorses, being small marine fish, are in high demand worldwide due to reasons such as Chinese medicine and beach souvenirs, which

has resulted in their removal from the ocean. This demand has made them somewhat endangered. These creatures are typically 1.6-20 cm in size and can be found in various colors, including shades of red, orange, yellow, gray, and green. Some seahorses also have body patterns such as zebra stripes or spots.

Seahorses, as members of the vertebra group, have an inner skeleton and are shielded by armored scales that double as ribs. They breathe through gills and lack a tail fin common among other fish species. These protective plates are likely a modified version of scales.

Seahorses are able to swiftly move upright through water, achieving hummingbird wing-like speeds with the assistance of their dorsal fin which can make up to seventy movements per minute. Steering and turning are accomplished using pectoral fins located near the neck. Each seahorse has a unique coronet on

its head, comparable to a human thumbprint. Because they lack stomachs, these creatures require large amounts of food like daphnia, cyclops, plankton, worms, larval fish and amphipods in order to survive. Although they don't have teeth for chewing food, one seahorse can consume three thousand brine shrimp daily.

Male and female seahorses can be distinguished by the smooth, white appearance of the male's lower abdomen (pouch). These creatures inhabit temperate and tropical waters near coastlines, often residing in environments such as sea grass, seaweed, mangroves, microalgae, and coral reefs. Wild seahorses are believed to have a lifespan that varies from one to five years depending on their species. In order to survive in their oceanic habitat, they possess various adaptations such as partial transparency or camouflage capabilities which help them remain concealed in seaweed or other secure locations to avoid predators.

Seahorses possess various survival techniques, such as leaf-shaped extensions that allow them to camouflage in kelp beds and avoid danger. Additionally, some types of seahorses are venomous, which makes them a threat to predators like crabs, tuna, skates, and stingrays. Moreover, their petite fins enable them to maneuver through thick underwater vegetation without entanglement.

Seahorses possess several adaptations that aid in their hunting abilities. Their eyes are highly mobile and move independently, providing a broader range of vision in dimly lit ocean environments. Additionally, they have developed long, tubular snout-like jaws that they use to suck up prey whole. This adaptation allows them to be ambush predators and snap up their food from up to an inch and a half away.

Among the numerous adaptations of seahorses, one of the most advantageous is their tail, which they use

to grasp onto support structures and underwater plants like seaweed and coral to avoid being swept away by the current and to rest. While these adaptations are fascinating, nothing is as remarkable as the reproductive process of seahorses, where the male carries the young.

It can be a surprising fact that seahorses are the only species where males carry and birth their babies, despite females typically being responsible for this in most animals. Female seahorses even compete for male partners, but still create the eggs, which they can do more quickly because they do not have to provide nourishment to their offspring. The eggs are then transferred to the male's pouch where fertilization occurs.

Seahorse dads cover the eggs with tissue and care for the offspring until birth, which typically occurs within two to three weeks. The seahorse dads experience frequent pregnancies, with labor lasting up to three hours and leaving them weak. The offspring are miniature replicas of their parents and become independent upon birth.

Although the father carries the pregnancy, only a few of the approximately 50 offspring born from his pouch will reach adulthood due to consumption by other fish or even by the father himself for nutrient replenishment. While seahorse reproduction differs from that of humans, with monogamy being common among many species, similarities exist in their social behavior, relationships and interactions.

Seahorses display unwavering loyalty by remaining devoted to their partner until death and engaging in intricate courtship rituals both at sunrise and sunset, similar to how humans tend to reiterate their dedication during these times before pursuing personal endeavors throughout the day. However, despite their captivating conduct, seahorses are often captured from their

natural environment and kept as pets.

Seahorses are often moved to tanks when purchased by humans, but this can be difficult for them since they are used to living in the ocean. In their natural environment, seahorses eat live brine shrimp and may be choosy eaters, posing challenges for their care in captivity. Additionally, being confined in an aquarium can lead to stress that compromises their immune system and increases susceptibility to illnesses.

Although purchasing a captive-bred seahorse may come at a higher cost, the trend towards this method of breeding is increasing. The benefits include a higher likelihood of survival when kept as pets in tanks and the ability to feed them frozen sea lice rather than live brine. Zulu-lulus, Mustangs, and Pixies are among the recommended varieties for those new to keeping seahorses. It is advised that they be housed alone in tanks whenever possible due to their slow feeding habits.

While seahorses are not able to thrive in tanks with faster fish, as they may not get enough nutrients and can eventually starve, they can coexist happily with shrimp and other bottom feeders like goby fish. It is crucial to avoid dangerous fish such as eels, triggerfish, squid, and sea anemones when keeping seahorses in tanks. The exact number of seahorses in the ocean is uncertain; however, they continue to be highly desired on land. China and Singapore serve as the primary importers of both living and dried seahorses.

Every year, the Chinese catch about 20 million seahorses and harvested approximately 70 tons in 2002. These seahorses are primarily used for medicinal purposes in traditional Chinese medicine and herbology. Typically, they are dried and ground into

powder form before being combined with other herbs to treat various illnesses. The Chinese have faith in seahorses' ability to cure impotence, asthma, arteriosclerosis, and reduce cholesterol levels.

Seahorses are considered a delicacy for cooking and used as souvenirs at beaches in various parts of the world. They are dried and utilized for crafting key chains, jewelry, glass domes, paperweight decorations, and more. However, they are often caught as "bycatch" by large shrimp nets, leading to the depletion of seahorse populations at certain locations.

Starting from May, CITES safeguarded all 34 seahorse species from international trade that might imperil their survival. Trading nations must demonstrate that their sales do not endanger wild populations, and vendors must obtain permits to sell seahorses. Additionally, a minimum size constraint for these creatures now safeguards the reproductive capability of younger seahorses. However, despite CITES' protection, seahorses remain vulnerable to natural calamities that threaten their well-being.

Seahorses are at risk due to their presence in vulnerable aquatic ecosystems, such as estuaries, mangrove stands, sea grasses, seaweeds, lagoons and coral reefs that are endangered by natural hazards like storms. These storms can displace seahorses from their holdfasts and leave them stranded or exhausted without a place for their tail to rest on. Moreover, the storms damage their habitats in kelp beds or sea grasses. It is important to note that despite being enchanting creatures of magnificence and awe, seahorses depend on the ocean for survival.

Rebecca Bowe's "The last roundup? Seahorses struggle for survival" argues that seahorses should not be kept as pets, used for untested medicine, or exploited commercially. Instead, these amazing creatures should be allowed to live freely in the vast

ocean where they can be closely observed, examined, and admired without harm.
