This squash was purchased last week. Murph was going to enjoy the final 1/3 of it, but not now. What I do, is after washing my darling lizard’s veggies, I slice off that which will be eaten & then toss the remainder into the refrigerator drawer. When I use it again I slice off the air-dried tip, toss it outside for a wild creature to eat & give to Murph another section of stated vegetable.That means this food has been cold for quite some time.
After purchasing the groceries & getting them home, I placed most of the vegetables into the refrigerator immediately. I do not know if the multi-legged perpetrator was DOA or if the coldness killed him or her. I know that insects will often get so cold they cannot move, so in case it was alive I put the whole thing outside. It resembles a superworm, a commonly purchased food supply for lizards:
…except it was darker, with a shorter body, and legs more like a caterpillar’s. I was grossed out by the unwarranted surprise, but wished (if it was dead as it appeared) it had passed away untrapped in our squash… outside, perhaps in the sunlight.
When I sliced the squash, it appeared as though a nasty bruise was in the flesh of it.
I hypothesized that it looked like no ordinary bruise.
I performed an autopsy with a surgeon’s accuracy, slicing carefully at the exact spot of suspicion. As seen in Exhibit B, the lighting of such reveals an unmarred insect individual.
My conclusion was correct.
The moral of the story is this: A bruise may tell a much deeper story, not all bruises are from bumps, not all bruises are visible, and finally, the living or the dead can be discovered at any moment – when or where we least expect it.
Lil’ Murph will be happy with his medley of food without the squash. I have to tell you, the next food items I prepared were organic arugula & a banana. Guess what. The banana was horribly bruised & soft. I had a passing paranoia directly after the encounter within the squash, so the banana was launched. It had a graceful flight out the back door to land as a meal for a critter or improve soil quality, or something, I don’t know. Check those bruises!
I think it would be interesting to see the world as every other creature does, if only for a fleeting moment! So what do lizards see?
Well…. Lizard (including geckos) and turtle retinas contain multicolored oil droplets in their photoreceptors, so they can perceive color. The opsin proteins in the cones in the eye are “calibrated” to detect different wavelengths. In many species, this enables them to see into the higher wavelengths beyond the scope of unaided human vision: into the UV range.
Nocturnal reptiles usually have smaller eyes than diurnal ones, but relatively large pupillary and lens aperture and cornea. This improves their light-gathering ability, but at the same time reduces visual acuity.
Lizards can focus on near and far by squeezing or stretching their lenses, using the ciliary muscles and annular pads. Pupils dilate and contract in response to light. Nocturnal geckos like the tokay have a stenopaic pupil: contracts into a vertical slit composed of a linear array of dots. Some nocturnal lizards have slit pupils, others are round. Lizards, unlike other reptiles, have a choroid body, called the conus papillaris. Projecting out into the vitrious humor, it nourishes the cornea.
The spectrum of sunlight includes infrared, “visible light” (the colors we see in the rainbow) and ultraviolet light, which is subdivided into UVA, UVB and UVC.
UVA, is essential. Many reptiles have extremely good color vision. Humans have three types of retinal cone cells for color vision, and their brains combine the information from these cells and perceive the blend as a certain color. Most reptiles, however, have a fourth cone type, which responds to UVA. These reptiles see a much more colorful rainbow than humans do, which makes providing natural lighting quite a challenge. This extra color perception is especially important to many reptile species in recognizing others of their species and even food items.
Some nocturnal geckos lack the red-sensitive cone, but their green-sensitive cone also responds to red light; they can certainly see it. Studies have even shown that some use their cone types for color vision in light similar to dim moonlight. Thus it is possible that “moonlight blue” or “red night light” lamps, which usually are much brighter than moonlight, alter these animals’ view of the twilight world.
Sunlight also has effects unrelated to conscious vision. A reptile’s eyes, and the parietal eye (third eye) in those species that have one, transmit information to other parts of its brain responsible for setting circadian (daily) and circannual (yearly) rhythms. There are even light-sensitive areas of the reptilian brain that respond directly to sunlight’s glow through the skull. The length of day and night, the sun’s position in the sky, and the intensity and amount of blue in sunlight all give precise information about the time of day and season of the year. In response, a reptile adjusts its activity levels, and daily and seasonal behaviors, such as its reproductive cycle and thermoregulation needs. Even nocturnal species govern their behavior by monitoring day and night from their daytime hiding places.
…So what have we learned if the study and testing conclusions are accurate?
Lizards do see colors.
Most reptiles actually see a much more colorful rainbow than we!
Most lizards have a parietal eye, known as the third eye, which is a photosensory organ.
Also, their pupils dilate and contract, same as ours, to focus on things near or further away.
I will further add to this by stating a lizard (specifically Bearded Dragons) close their eyes for 4 reasons: a) You are overstimulating at the moment OR they don’t like you AND they want you to go away. b) They are sleepy. c) They are at this very moment, in perfect peace with their environment & existence. d) They are feeling love from or toward you right now.
