In the past, I have posted some of my images obtained on a "macro trip" to Costa Rica. A large majority of the photos taken were "set ups". By set up, I mean that the subject was taken from where it was found in the wild, placed on a perch of our choosing with a background of our choosing, and then photos were taken. Often, two flashes were used that were set up somewhat in front of, and to the side of, the subject. After the images were taken, the subject was returned to where it was found. We did our best to handle the animals gently and touch them as little as possible. The images obtained can be spectacular and careful selection of perch and background can make them really show off the animal well. Just exactly where you draw the line in such circumstances is up to you. Please, let's not turn this presentation into a discussion of ethics. We all have a line we won't cross. These images are close to, but not across, my line.
1. Lichen-colored Snail Sucker. This has to be one of the weirdest names of any animal! Despite their name, they mostly eat amphibian eggs, although they will also eat worms, slugs, and snails.

2. Eyelash Pit Viper. This is one of the more commonly seen poisonous snakes in Costa Rica. These snakes are named for the superciliary scales the look like eyelashes, seen well in this image. The species comes in at least 13 different color morphs, and the individual snake's behavior depends somewhat on which morph they express. The yellow morph often sits on flowers, trying to blend in, and sticks out at any birds that come in to feed on the flower.

3. Central American Boa. This species has recently been elevated from subspecies status by some authorities, based on DNA sequencing differences from the boa constrictors of South America. These snakes grow up to 7 feet in length, and, as the name suggests, they kill their prey by grabbing them with their mouths, coiling their body around the prey, and squeezing. The prey dies of suffocation.
Nikon Z9, Nikon 24-70mm f/2.8E VR, 1/125 second @ f/5.6, ISO 640.
4. Annulated Tree Boa. As their name suggests, these snakes are characterized by the pattern of rings in their coloration. They are constrictors.
Nikon Z9, Nikon MC 105 mm f/2.8 VR S, 1/200 second @ f/5.0, ISO 500.
5. Central American Jumping Pit Viper. As this image shows, this viper really blends in well with fallen leaves on the ground. They are responsible for the most venomous snake bites in Costa Rica. The name is a misnomer, these snakes don't really jump of the ground. However, they are aggessive strikers and may lift much of their body off the ground when striking.
Nikon Z9, Nikon MC 105mm VR S, 1/100 second @ f/10, ISO 1000, flash.
