ST. LOUIS — The public will be able to name three of the St. Louis Aquarium’s first residents.

Aquarium officials announced Monday morning they will hold a naming contest for the new otter family.

There are three choices to vote on:

Splish, Splash and Dash (based on otter movements and behavior)

Hopper, Zephyr and Harvey (based on train themes)

Thatcher, Sawyer and Finn (based on characters from Mark Twain novels)

The aquarium also offered some personality traits about each otter to help voters pick the best names.

The little brother has big feet, a big nose and is very eager to learn. The middle sister is the peacemaker, the aquarium wrote on Facebook, and is often distracted by someone cleaning her habitat. The big sister is in charge and loves to swim. Even though they have several sleeping options and a lot of space, they choose to sleep snuggled up together.

The public can pick their favorite names on the St. Louis Aquarium’s Facebook page by clicking here. Voting will remain open until Monday, Sept. 23.

St. Louis Aquarium at Union Station We just took a DNA test, turns out we're 100% that cute even though ... we don't have names yet! Here's where you come in! Help us name our 3 furry otter friends!

The three otters arrived in St. Louis earlier this month from their previous home at Flamingo Gardens in Florida. They’re currently living off-site while their future home is still under construction.

The St. Louis Aquarium hasn't announced an official opening date yet, only that it'll be sometime in December.
