It evolves into Seadra starting at level 32, which evolves into Kingdra when traded while holding a Dragon Scale.
(Specifics may differ in past games. Refer to Game data→Evolution data for these details.)
Biology
Horsea is a light blue, piscine Pokémon 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.
(For specifics on this Pokémon's evolution in the games, refer to Game data→Evolution data.)

Trivia
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 Kalosian Goodra. 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, tatsu-no-otoshigo (dragon's child), 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.
Tattu may be derived from 竜 tatsu (dragon) or 竜の落し子 tatsu-no-otoshigo (seahorse, lit. "illegitimate child of a dragon").
