Those who believe that sharks roam restlessly during the day in search of food are mistaken. The wisdom of 'carpe diem' is used especially by the tropical nurse sharks, who live in groups, when it comes to sleeping. During the day they are happy to rest in caves or under ledges or even just sleep how we would understand to be 'normal'.
The blacktip reef shark is considered extremely agile. The visitors to Aquarium Berlin can also observe its sudden turning maneuvers. It is not uncommon for our submerged keepers to be startled when cleaning the panes. It's no wonder, the sharks approach them at speeds of up to 30 km/h and only turn in another direction right before collision – enough to make anyone wince.
... Shark teeth regrow on a life-long basis? Practical or what? Shark teeth are not firmly anchored in the jaw, but only loosely attached to the softer jaw cartilage. Mother Nature therefore equipped all shark species with a set of teeth, which constantly 'reload' – a so-called set of revolver teeth. As a result, they don't just have one row of teeth, but many in succession. If a shark tooth falls out or breaks off, it is succeeded by a new tooth from the jaw and within a few weeks, the gap is filled again.
