In the marine world, there exists a fascinating creature with a "strange" appearance. It has a head resembling that of a horse, a pointed tube-like mouth, and lacks teeth. This extraordinary creature is the seahorse, which possesses a unique swimming style.
Scientists have identified at least 45 different shapes, sizes, and colors of seahorses, making them truly captivating to observe. What makes these little creatures so amazing？
1. Seahorse skeletons possess exceptional flexibility and strength. Although they may appear delicate, seahorses can withstand high pressure.
Their hard-boned fish structure is fortified by circular bone plates that extend along their bodies, resembling a string of flexible armor. When subjected to external force, these plates slide against each other, dispersing the pressure.
2. Despite being fish, seahorses are notoriously slow swimmers. Distinguished by their unique anatomy, which includes a neck, seahorses have an upright body posture while swimming.
Lacking the aid of a tail fin, they rely solely on their small dorsal fin for propulsion, resulting in sluggish movements.
3. Interestingly, seahorses lack a stomach. Consequently, they have no storage space for food, and whatever they consume quickly passes through their digestive system.
This leads seahorses to constantly eat without pause, as they have narrow mouths resembling powerful vacuum heads. Due to their absence of teeth, they rely on suction to swiftly consume their prey, devouring approximately 3000 shrimp per day.
4. Seahorses possess the ability to move their eyes independently. For instance, one eye can focus on the left while the other gazes towards the right.
This unique adaptation expands their field of vision, enabling them to monitor a wider range of their surroundings and be vigilant for potential prey.
5. Seahorses are capable of changing their body coloration, primarily for camouflage purposes. Additionally, they can alter their coloration when feeling frightened or nervous, serving as a means of communication or self-defense.
6. To prevent drifting away, seahorses cleverly wrap their prehensile tails around corals, ensuring they remain securely anchored.
7. Many seahorse species are endangered. While a seahorse couple can produce over a thousand offspring at a time, only a fraction, ranging from 0.1% to 0.5%, survive to adulthood.
Once born, young seahorses must navigate the world independently while hiding from predators. Moreover, their habitats, including coral reefs, seagrass beds, and mangroves, are sensitive ecosystems often threatened by pollution and marine debris.
Combined with the fact that seahorses are frequently hunted for medicinal purposes, their population numbers are dwindling due to multiple factors.
Efforts to protect and conserve these remarkable creatures are crucial to their survival and the preservation of our delicate marine ecosystems.
