The black-footed, or African, penguin does not dwell on the ice like so many of its cousins. Instead, it lives in cold currents off the coast of South Africa. These noisy birds are also known as “jackass penguins” because of their shrill calls. They bray for mate recognition, when angry, or to say hello.
The loudest voices in the ocean may be the gregarious California sea lion. Though clumsy on land, this marine mammal is a strong swimmer and diver, aided by its oar-like flippers and torpedo-shaped body. Sea lions belong to an animal group called “pinnipeds,” which means “feather-footed” and refers to their long, flattened hands and feet.
With its purple-tipped green tentacles and domed shape, it’s no wonder this jelly has such a fashionable name. The flower hat jelly is a type of stinger—also known as a cnidarian (pronounced “Ni-dare-ee-an”). Cnidarians are an ancient and primitive form of life. The family includes jellies, corals, and anemones.
Giant Pacific octopuses are one of the largest octopus species. They are relatives of squid and part of the cephalopod class of animals. The name “cephalopod” means “head-foot,” and refers to the attachment of the tentacles to the head. Cephalopods have the largest brains of any invertebrate. Octopuses and squid in particular are two of the quickest learners, and best at retaining information.
