Jellyfish have a complex life cycle that includes both a sexual stage and an asexual stage.

In the sexual stage, the body (called a medusa) produces gametes (eggs and sperm). Then the eggs fertilized by sperm develop into a free-swimming larval form called planula.

After a brief period floating about in surface waters, the larvae settle to the sea floor, attaching themselves to a rock or the seafloor. They develop into a polyp (asexual stage) and begin to feed and grow.

In spring, some of the polyps start to bud off immature jellyfish known as ephyra larvae. These grow into mature jellyfish.

Mount Teide is a volcano on Tenerife in the Canary Islands, Spain. Its summit is the highest point in Spain and the highest point above sea level in the islands of the Atlantic.

Hovering above the volcano there's a spectacular lenticular cloud. Lenticular clouds are stationary clouds that form mostly in the troposphere, typically in parallel alignment to the wind direction

This effect happens when the camera frame rate matches the helicopter's rotor RPMs. Each frame captures the blades quickly enough that they look like they are standing still

Left ventricular thrombus (LVT) is a blood clot (thrombus) in the left ventricle of the heart. LVT is a common complication of acute myocardial infarction (AMI). Typically the clot is a mural thrombus, meaning it is on the wall of the ventricle.

The primary risk of LVT is the occurrence of cardiac embolism, in which the thrombus detaches from the ventricular wall and travels through the circulation and blocks blood vessels.

Blockage can be especially damaging in the heart (infarction) or brain (stroke).

The eiderdown is a type of down feather, which is a soft and fine layer of feathers located under the bird's tougher exterior feathers.

The female eider duck plucks the feathers off her chest into her nest in order to keep her eggs and young warm.

The ocellated turkey (Meleagris ocellata) is a species of turkey residing primarily in the Yucatán Peninsula, Mexico, as well as in parts of Belize and Guatemala.

A relative of the North American wild turkey (Meleagris gallopavo), it was sometimes previously considered in a genus of its own (Agriocharis), but the differences between the two turkeys are currently considered too small to justify generic segregation.

It is a relatively large bird, at around 70–122 cm (28–48 in) long and an average weight of 3 kg (6.6 lb) in females and 5 kg (11 lb) in males

You can see chromatin condensing into chromosomes before being pulled apart. The nucleus is visible because cells were tagged with a protein called Histone-mCerry that binds to DNA
