The mammalian diving reflex refers to an adaptive characteristic that permits the mammals to stay underwater for an elongated duration of time. It is more noticeable in aquatic mammals, however, is weaker in mammals like humans.  

This reflex is initiated when the face encounters with cold water. The initial influence is bradycardia in which the rate of the heart slows down up to 25 percent. There is peripheral vasoconstriction that comprises a reduction in the supply of blood to the arms and legs, and the supply upsurges towards the brain.  

It can be stated that in humans, it is not an evolutionary vestige, but yes it is not much amended as aquatic mammals due to their terrestrial habitat.

Answer:

I'd need the data from the population sizes of the algae, walleye pollock, orca, ocean sunfish and sea turtles. And I'd also need water temperature data, levels of dissolved oxygen.

Explanation:

The jellyfish population may have increased because of an increase in phytoplankton. This leads to an increase in

zooplankton; a decrease in walleye pollock, leading to an increase in zooplankton; or an increase in orcas, leading to a

decrease in sea turtles. Sea turtles, being the main predator for keeping the jellyfish population in check.

Also, if there are more red algae, jellyfish polyps have less place to grow. Without it, the polyps can attach itself on every surface.
