Horsea is a small, blue, seahorse-like Pokémon with a single dorsal fin and a tightly curled tail. Its eyes are red and its ridged belly and dorsal fin are cream-colored. It has a long, tubular mouth and three spike-like projections on either side of its head.
It is highly adept in the water, using its dorsal fin to swim in any direction while facing forward. It can use its tail as both a balance and an anchor when caught in a strong current. In safer environments, it uses its tail to play with other members of its species. If Horsea senses danger, it sprays water or dense black ink from its mouth at its attacker. It can shoot ink more precisely at insects flying above the surface of the water. Horsea feeds on insects and moss gathered from rocks. It nests in coral reefs and islands throughout the ocean. Many Eggs are laid every year, and the young are raised by the male Horsea rather than the female.
Horsea, a Dragon Pokémon. In this unique Pokémon species, thousands of Eggs hatch every spring, and then the male raises them himself.

Green had a Horsea in Zap! Zap! Zapdos! on her team that she received from Silver in exchange for her Snubbull following their escape from the Masked Man, using it in her crafty tricks such as cloaking areas with Smokescreen or leaving ink trails. It was later transferred back to Silver, and eventually evolved into Kingdra.
Horsea appeared in ''Breath of the Dragonair Part 1 where it was used by a trainer in a surfing contest, before the it was interrupted by Lance controlling the winning prize, a Dragonair.
Lance's Horsea was seen in a flashback of his and Clair's childhood.
Horsea eats small insects and moss off of rocks. If the ocean current turns fast, this Pokémon anchors itself by wrapping its tail around rocks or coral to prevent being washed away.
If Horsea senses danger, it will reflexively spray a dense black ink from its mouth and try to escape. This Pokémon swims by cleverly flapping the fins on its back.

Horsea and its evolutions share their category with Dratini, its evolutions, Salamence, and Goodra. They are all known as the Dragon Pokémon.
In its original artwork, Horsea had a pair of fins instead of just one.
Origin
Horsea is based on a seahorse, though its ability to shoot ink resembles that of a squid. The fact that it's known as the Dragon Pokémon might be a reference to leafy sea dragons.
Name origin
Horsea is derived from seahorse with reversed syllables, and a corruption of the diminutive horsie.
Tattu is a corruption of 竜 tatsu (dragon), which is part of the common name of a seahorse in Japanese: 竜の落し子 tatsu-no-otoshigo ("illegitimate child of a dragon").
