Monkeys are captured, chained, starved, beaten, and often have their teeth pulled out, all to force them to perform tricks or beg tourists for money. Visit monkeys in sanctuaries instead.

Tarsiers are tiny primates that are endangered due to habitat destruction, hunters, pet trade and tourist attractions, where they're often kept in in poor conditions, so it's important to only visit them a certified humane sanctuary.

Asian palm civets are captured from the wild, confined in small cages, deprived of their natural diets, and instead fed coffee cherries to poop out so tourists can drink the coffee made from their feces called Kopi Luwak. Yes, this is totally disgusting.

Don't touch or pick up sea turtles or try to 'assist' baby sea turtles getting to the sea. Sea turtle tourist attractions confine, mistreat and even kill the turtles. Tourists often harass turtles in the wild, causing harm, injury and death. 

The boats used to take tourists out to sea harm whales by interfering with their communication, breathing, feeding and reproduction. Familiarity of boats also makes them more susceptible to commercial hunting and whaling.

Swimming with stingrays affects their behavior and feeding patterns and causes them stress and weaker immune systems. They're also often injured and disfigured by boats.

Interacting with or touching manatees is not only wrong, it's illegal. Disturbing them can affect their natural feeding, safety and behavior. Also, boats.

Elephants are kidnapped from their families and imprisoned to a life of torture where they are beaten into submission with barbaric instruments like steel hooks called bullhooks. And, they cry. Because they're sad.

Visit elephants in sanctuaries instead.

Camels are mistreated and abused for rides and photos. They're chained, muzzled, beat with hooks, starved and tied together and riden, causing stress, painful joint diseases and arthritis, and also diseases from exposure.

Ostriches cannot safely support the weight of humans and riding is unnatural, painful and cruel to the birds kept captive just to be used and abused.

Riding horses, and donkeys, is also unnatural. The weight and pressure cause bone, joint and muscle stress, and the bits, whips and spurs cause pain and injury.

Horses are forced to perform excruciating physical labor pulling carts in street traffic in extreme weather, and they're often worked to death, dropping dead on the job, and causing horrific accidents.

A bloodsport in which birds are forced to fight in an inescapable pit with blades attached to their legs where they sustain injuries such as lacerations, punctured eyes and lungs, broken bones, and death.

Snakes used in snake charming and snake kissing have their fangs are pulled out with pliers, venom ducts blocked or removed, and sometimes their mouths are sewn shut, and then they're starved so they're forced to come out for food.

Marine parks and aquariums capture and confine aquatic creatures to small, unnatural tanks where they suffer stress, overcrowding, disease, and death.

Crocodile farms, who overbreed crocodiles for their flesh and hide, cause the crocs stress and injuries at the farm and then an agonizing death as they're cut open, spinal cords severed, skinned alive, and left to die in total agony.
