What Animals Are Blind. I freely assume that by “blind”, this question means that the animals have no eyes or any means of light receptor to detect objects through visible light. Proof of the adaptation is within the fish shortage of eyes.
For this reason, blindness in animals is a research topic that is unique. Things don't go exactly as expected. A gray whale swam halfway across the world, setting a new record.
A person or another animal that approaches the blind pet without foreknowledge of the vision deficit may startle or frighten the pet and initiate a fight or flight reaction.
I freely assume that by “blind”, this question means that the animals have no eyes or any means of light receptor to detect objects through visible light. Star nosed mole is a real animal (not known to many people). The animals that live in caves are known as troglobites, and they are similar to those living in the deep seas which live in perpetual darkness and are therefore blind without the need of eyes, and they have other specialized senses that compensate for the lack of eyes. Other animals that are totally color blind, or monochromats, include dolphins and walruses.
