Jellyfish are a familiar sight in Port Phillip, and its waters are home to species such as Australian fur seals, bottlenose dolphins, common dolphins, humpback whales, and southern right whales. Many other cetacean species may also migrate off the areas. The smooth toadfish is one of the most common fishes in muddy areas. The bay has many endemic species including the bluedevil fish and fantastic sponge walls on the Lonsdale wall in the heads of the bay. It also hosts breeding colonies of Australian fur seals. Occasionally, Australian sea lions, New Zealand fur seals, subantarctic fur seals, and leopard seals may come into the bay as well. Certain individual southern elephant seals may frequent the bay as well.
