When hunting, they can “sense” prey, unseen, up to a foot away. Like most sharks, sand tigers are able to detect electrical signals emitted by potential prey in the water column or substrate with specialized electrosensory organs on the sides of their head and lower jaw called ampullae of Lorenzini that enable them to find
On Pond Island, one of Project Puffin’s smallest research islands which focuses on studying and protecting common terns, the seabird biologists found signs that a Great Horned Owl was hunting in the tern colony. The biggest indication was that the colony of common terns were “dreading” each evening and abandoning the island for the night
Osprey have amazing vision. Researches have studied their vision when they fish. Osprey have been measured to be anywhere between 5-40 meters above the water before performing a spectacular dive on their pray below. In some parts of the world, Senegal for example, it’s been noted that Ospreys will circle 100-300 meters above the water.
After a warm migratory season, (one that can range as far down as Venezuela) you might suspect Ospreys tend to stay away from cold, snowy climates. Scientists have gathered that Ospreys “shake it off” as long as these conditions apply: 1) Accessibility to fish in shallow waters. 2) Predator-free nesting area. 3) A perch in
