Fruit Fly Antenna
This photograph was taken with a Scanning Electron Microscope.
It demonstrates antenna structures in the fruit fly Drosophila melanogaster. Specifically, the primary structure seen in this photo is the Funniculus, the base of which is sheathed into the Scape behind it. Additionally, at the top-right of the frame, we see the Arista itself.
Fruit Fly Foot
The foot of the fruit fly, Drosophila melanogaster. The exoskeleton on its limbs exhibit a texture analogous to wood. The hinged structure of their feet can provide strong traction, even on curved surfaces.
Mosquito Foot
Another foot of the Aedis Aegypti.
There are important distinctions seen in this photo, as compared to the last. Whereas the other Aegypti leg had scales protruding from the tarsal claws themselves, this one does not. Additionally, there is a much greater presence of sensory hairs to give tactile feedback to the organism. This leg also exhibits both tarsal claws.
Mosquito Leg
The leg of a Mosquito, Aedis Aegypti. A concentrated presence of scales can be seen running along the length of the limb. Additionally, we note a Tarsal Claw at the end of this extremity.
Mosquito Head
This SEM photo demonstrates the delicate structures of the Aedis Aegypti head. The majority of its surface is covered with photoreceptor units - Ommatidia - with hundreds of these comprising this insect's compound eye.
We also see the antenna "ports" of this mosquito above and at the forefront of this compound eye. Finally, the palps directly in front of this mosquito's chin are visible.
Proboscis
The Proboscis of an Aedis Aegypti mosquito. The tapered end penetrates the skin, whereas the Labium unsheaths the length of the proboscis, rolling up against the skin.
The Proboscis injects an anti-coagulant into the bloodstream before extracting the blood.
Western Golden Shiner Nostril
A close photo of the nostrils of a Western Golden Shiner fish. These structures exhibit 2 types of sensory cells - Microvilli, and Cilia (the long, hair-like structure).
Pollens
The pollen in the top-left of this photo was extracted from a Salt Bush. It exhibits a pocked exterior, with a variety of depressions on its surface.
The counterpart is a pollen grain sourced from a Sunflower.
