John Lloyd of We Love This book says The Book of Barely Imagined Beings is:

[a] superb book...[It] is no polemic. Yes, it carries in its gorgeous pages eco-lessons galore, but it’s so much more – philosophical, spiritual, cultural. It combines science and literature and shows quite how brilliant mankind’s general knowledge can be – and also how little we know about our world and what we continue to do to it. In that regard it’s an essential volume, of a kind so seldom accomplished as successfully as this.

Not really a review, but Nature has this in its paywalled Books in Brief section:

Award-winning writer Caspar Henderson read Jorge Luis Borges's The Book of Imaginary Beings (1967) and realized that nature's creations often trump the fantastical for sheer surreality. Henderson's mainly marine beasts are a dazzling catch. The “genital fingered”, gherkin-sized stomatopod Gonodactylus smithii, for instance, uses specialized limbs for defence — delivering enough force to break a bone. Eels, whales, arachnids and more are examined, with Henderson's central concern the survival of all this glory in the midst of the biodiversity drain. Wittily illustrated by Golbanou Moghaddas.
