Invertebrate Quotes (6 quotes)

Here are a few things to keep in mind the next time ants show up in the potato salad. The 8,800 known species of the family Formicidae make up from 10% to 15% of the world's animal biomass, the total weight of all fauna. They are the most dominant social insect in the world, found almost everywhere except in the polar regions. Ants turn more soil than earthworms; they prune, weed and police most of the earth's carrion. Among the most gregarious of creatures, they are equipped with a sophisticated chemical communications system. To appreciate the strength and speed of this pesky invertebrate, consider that a leaf cutter the size of a man could run repeated four-minute miles while carrying 750 lbs. of potato salad.
From book review, 'Nature: Splendor in The Grass', Time (3 Sep 1990).

I can no more explain why I like “natural history” than why I like California canned peaches; nor why I do not care for that enormous brand of natural history which deals with invertebrates any more than why I do not care for brandied peaches. All I can say is that almost as soon as I began to read at all I began to like to read about the natural history of beasts and birds and the more formidable or interesting reptiles and fishes.
In 'My Life as a Naturalist', American Museum Journal (May 1918), 18, 321. As cited in Maurice Garland Fulton (ed.) Roosevelt's Writings: Selections from the Writings of Theodore Roosevelt (1920), 247.

If we and the rest of the backboned animals were to disappear overnight, the rest of the world would get on pretty well. But if [the invertebrates] were to disappear, the world’s ecosystems would collapse. disappear, the land’s ecosystems would collapse. The soil would lose its fertility. Many of the plants would no longer be pollinated. Lots of animals, amphibians, reptiles, birds, mammals would have nothing to eat. And our fields and pastures would be covered with dung and carrion.
From BBC TV series Life in the Undergrowth (2005). As cited in Simon Barnes, History of the World in 100 Animals (2020), end of Chap. 72.

The central nerve chain of an invertebrate such as the lobster runs beneath its alimentary canal, whereas the main portion of its rudimentary brain is placed above it, in its forehead. In other words, the lobster’s gullet, from mouth to stomach, has to pass through the midst of its brain ganglia. If its brain were to expand—and expand it must if the lobster is to grow in wisdom—its gullet would be squeezed and it would starve.
In Epilogue, The Sleepwalkers: A History of Man’s Changing Vision of the Universe (1959), 516.

The invertebrated classes include the most numerous and diversified forms of the Animal Kingdom. At the very beginning of our inquiries into their vital powers and acts we are impressed with their important relations to the maintenance of life and organization on this planet, and their influence in purifying the sea and augmenting and enriching the land—relations of which the physiologist conversant only with the vertebrated animals must have remained ignorant.
In Lecture, delivered at the Royal College of Surgeons, collected in Lecture 24, 'Cephalopoda', Lectures on the Comparative Anatomy and Physiology of the Invertebrate Animals (1843), Vol. 1, 362.

Wherever we go on land, these small creatures [insects, worms] are within a few inches of our feet—often disregarded. We would do very well to remember them.
From BBC TV series Life in the Undergrowth (2005), as quoted in BBC press release (10 Oct 2005).

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
