Horsea is a light blue, piscinePokémon that is similar to a seahorse. It has red eyes, a long, tubular mouth, and three spike-like fins on either side of its head. Its ridged belly and single dorsal fin are cream-colored. Highly adept in the water, it uses its dorsal fin to swim in any direction while facing forward. It has a tightly curled tail that it can use 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.
Horsea feeds on insects and moss gathered from rocks. If Horsea senses danger, it sprays water or dense black ink from its mouth at its attacker. It can shoot more precisely at insects flying above the surface of the water. Horsea nests in coral reefs and islands throughout oceans with gentle currents. Many Eggs are laid every year, and the young are raised by the male Horsea rather than the female. Horsea swims with dance-like motions, creating whirlpools in the process. It tends to compete with each other to see who can create the biggest whirlpool.
Evolution
Horsea evolves into Seadra, which evolves into Kingdra.
If attacked by a larger enemy, it quickly swims to safety by adeptly controlling its dorsal fin. (Pokémon Red, Silver, or Crystal inserted) Its big, developed fins move rapidly, allowing it to swim backward while still facing forward. (Pokémon Blue, Gold, or Yellow inserted)
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.

In Alola, Kanto!, four Horsea were seen at Professor Oak's Laboratory. A fifth was featured in Lana's fantasy about the Pokémon that she hoped to see in Kanto.
Green had a Horsea in Zap! Zap! Zapdos! on her team that she received from Silver in exchange for her Granbull following their escape from the Masked Man. She used her in her crafty tricks such as cloaking areas with Smokescreen or leaving ink trails. She was later transferred back to Silver, and eventually evolved into Kingdra.
A Horsea appeared in ''Breath of the Dragonair Part 1, under the ownership of a Trainer. It was used in a surfing contest, before it was interrupted by Lance controlling the winning prize, a Dragonair.
Horsea's Red and Blue artwork depicting it with two fins instead of one
Horsea and its evolved forms share their category with Dratini, its evolved forms, Salamence, and KalosianGoodra. They are all known as the Dragon Pokémon.
Horsea's artwork from Pokémon Red and Blue depicted it with two fins instead of one. This two finned design was referenced in Alola, Kanto!
Origin
Horsea seems to be based on a seahorse. Its category may be a reference to the Japanese word for seahorse, 竜の落とし子 tatsu-no-otoshigo (literally "illegitimate child of a dragon"), which is derived from the myth that a seahorse that lives for a century will transform into a dragon. Its ability to shoot ink is reminiscent of a squid, and the shape of its snout and Sniper Ability are reminiscent of a water gun.
Name origin
Horsea may be derived from seahorse and horsie (childish term for a horse).
Tattu may be derived from 竜 tatsu (dragon) or 竜の落とし子 tatsu-no-otoshigo (seahorse, lit. "illegitimate child of a dragon").
