Fish & Invertebrates

  • American Eel
  • Size: 60 inches in length and can weigh up to 16 pounds

    Diet: Larval fish, gastropods, larger finfish, frogs, toads, crabs, lobsters and worms

    Lifespan:  40 years

    Range: The American eel is found in the northwestern to central Atlantic Ocean and throughout the Great Lakes. They range down the Atlantic Coast of the United States, to the Gulf of Mexico, including the West Indies to Trinidad.

    Predators: Sharks and bass prey upon adult eels.

    Conservation Status: American eels are not listed in the IUCN Red List (World Conservation Union), but they have not been evaluated recently. They have no special Federal status. Concerns have been raised about over fishing the elver stage leaving fewer eels to reach adulthood. The American eel is also vulnerable to habitat loss through projects and pollution. In the Great Lakes, the population of American eels has been drastically reduced.

  • Axolotl
  • axolotl

    Size: 9 inches

    Diet: Small crustaceans, fish, plants

    Lifespan: 15 years

    Range: Mexico City

    Predators: Humans, birds, large fish

    Conservation Status: Critically endangered. There are no axolotls left in the wild, their habitat has been completely destroyed by humans and is unlivable. They are not extinct because they flourish under human care and can be found in many aquariums.

  • Balloon Fish
  • Size: 8 to 14 inches

    Diet: Mollusks, crabs, urchins, algae

    Lifespan: 3 to 5 years

    Range: Indian, Pacific and Atlantic oceans

    Conservation Status: The IUCN (World Conservation Union) has recently downgraded the lake sturgeon from threatened to a species of least concern.

    The Aquarium of Niagara is proud to be a part of NYS DEC Lake Sturgeon Restoration Program. Lake sturgeon are born at a hatchery and then placed under our care until they are strong enough to be released into Lake Ontario to help the lake sturgeon population.

  • Lionfish
  • fish

    Size:  12 to 15 inches in length and weighs about 2 pounds

    Diet: Crabs, small fish, and various shrimp

    Lifespan: 15 years

    Range: Native to the Indo-Pacific near shore area and around coral reefs. Due most likely to release by hobbyists, the red lionfish is now found from Long Island to Florida in bays, estuaries and harbors as well as along beaches and coral reefs. This invasive species has also been reported off the San Francisco coastline.

    Predators: Predators of adult red lionfish are unknown. Sharks, especially sand tigers, may eat them, as they have been known to eat venomous fish.

    Conservation Status: The lionfish is not listed by the IUCN (World Conservation Union) as threatened or vulnerable. Any wild occurrences in the United States should be reported to NOAA. It is not likely that the introduction of this fish to United States waters can be reversed.

    The lionfish is an invasive species and with their increasing population, they are destroying ecosystems. There is a huge push to hunt lionfish and eat them, there are countless cookbooks on how to cook and eat lionfish.
