"Higher animals" is a catch-all term for vertebrates other than fish. This is rather self-congratulatory, since the so-called "lower animals" - fishes and invertebrates - are actually the dominant species on the planet, both in numbers and diversity! The four classes of higher animals are:

• Amphibians - class Amphibia
• Reptiles - class Reptilia
• Birds - class Aves
• Mammals - class Mammalia

Of these, amphibians are absent from marine environments ( with one or two exceptions. )
