The invertebrate chordate classes are from Fishes of the World.

Scientists have described between 96,660 and 128,843 invertebrate species in Brazil alone.

The complement system and phagocytic cells are also used by most forms of invertebrate life.

A proboscis is an elongated appendage from the head of an animal, either a vertebrate or an invertebrate.

Poxviruses (members of the family Poxviridae) are viruses that can, as a family, infect both vertebrate and invertebrate animals.

Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts.

Phagocytosis probably represents the oldest form of host defense, as phagocytes have been identified in both vertebrate and invertebrate animals.

Neurons are the core components of the brain, the vertebrate spinal cord, the invertebrate ventral nerve cord, and the peripheral nerves.

Endophytic fungi of grasses of the genus Neotyphodium , such as N. coenophialum , produce alkaloids that are toxic to a range of invertebrate and vertebrate herbivores.

Fish, reptiles, birds, and naming of dinosaurs Owen's technical descriptions of the Vertebrata were still more numerous and extensive than those of the invertebrate animals.

Neurotransmitters, second messenger systems, protein kinases, ion channels, and transcription factors like CREB have been confirmed to function in both vertebrate and invertebrate learning and memory storage.

But the only way I can describe what I was seeing that day was that this octopus was playing, which is a pretty sophisticated behavior for a mere invertebrate.

Antimicrobial peptides called defensins are an evolutionarily conserved component of the innate immune response found in all animals and plants, and represent the main form of invertebrate systemic immunity.

While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system.

In 1917 he became a contributor to the newspaper El Sol , where he published, as a series of essays, his two principal works España invertebrada ( Invertebrate Spain ) and La rebelión de las masas ( The Revolt of the Masses ).

And the aquarium had a lot of big fish tanks but not a lot of invertebrate displays, and being the spineless guy, I thought, well I'll just go out in the field and collect these wonderful animals I had been learning about as a student and bring them in, and I built these elaborate sets and put them on display.

So here's two sort of canonical neurons from a vertebrate and an invertebrate, a human pyramidal neuron from Ramon y Cajal, and another cell to the right, a non spiking interneuron, and this is the work of Alan Watson and Malcolm Burrows many years ago, and Malcolm Burrows came up with a pretty interesting idea based on the fact that this neuron from a locust does not fire action potentials.
