Hippocampus Erectus

Hippocampus Erectus

The lined seahorse (Hippocampus erectus), northern seahorse or spotted seahorse is a species of fish that belongs to the Syngnathidae family. H. erectus is a diurnal species with an approximate length of 15 centimeters (6 inches) and lifespan of one to four years. The H. erectus species consists of a broad color spectrum, ranging from greys and blacks to reds, greens, and oranges. The lined seahorse resides in the Atlantic Ocean from Canada down to the Caribbean, Mexico, and Venezuela. It swims in an erect position and uses its dorsal and pectoral fins to guide itself when propelling through the water.Lined seahorses feed mainly on minute crustaceans and brine shrimp, which they suck in through their snout. Since the species consists of weak swimmers, they must ambush their prey by blending into their surroundings, which they do rather easily. The lined seahorse has eyes that can move independently of one another, allowing it to scan its surroundings rather easily and quickly. The species is sexually dimorphic, meaning it is easy to distinguish between a male and female lined seahorse; the males are larger and have longer tails. The lined seahorse is monogamous and perform ritual dances every morning in order to establish a bond with its mate, in addition to the clicking sounds and embraces that occur when they initially find their mate. If either the male or female should die, its mate would take time before replacing it with a new mate, if it does not die due to its short lifespan.
