Soft bodied animals like caterpillars often fall a prey to voracious hunters like birds or reptiles. Despite having no means to 'actively' defend themselves, with weapons like claws or jaws, they have nevertheless, evolved other equally effective deterrents. A particular species of the caterpillar lives at an altitude over 2.500 metres in the Himalayas. It uses prominent colour to inform would be predators of its inedibility.
In the event that an inexperienced or adventurous bird did eat the caterpillar, it would probably vomit it soon after, and subsequently desist from attacking similar species in future. Though this would do the unfortunate victim no good, the species benefits. A rare example of the martyr among animals.
The expression "other equally effective deterrents" mean
preventive weapons which have equal effect as others
mechanism which scares everyone equally well
preventive equipment which it is as effective as something that has been already mentioned in the passage
deterrents that are as powerful as those the caterpillars have
