 Do Giant Cookiecutter Shark Exist?
Both are about the same size--reaching lengths of around 50 cm--and both belong to a family of deep water squaloid (Squaliformes--the dogfish sharks) sharks: Dalatiidae (the sleeper sharks belong to this family as well).
The two Isistius species are epi- to mesopelagic creatures; it is thought that during the day they remain in the mesopelagic zone (from 200 m to 1000 m below sea level) and then at night they venture nearer to the surface.
Furthermore, sleeper sharks are closely related to the cookiecutter sharks as they reside in the same family, Dalatiidae, so there biting styles and appearance of bites may be similar.

Medial teeth are small, often symmetrical but may be asymmetrical and occur at the juncture of the left and right jaws.
These teeth are found in the Scyliorhinidae, Triakidae, Pseudotriakidae, Carcharhinidae, Sphyrnidae, Hexanchidae, Squalidae, Dalatiidae and Heterodontidae.
Symphyseal teeth have asymmetrical roots and occur on either side of the symphysis usually in the lower jaw but may occur in the upper jaw; they usually look like miniatures of the first anterior teeth.

 Dalatiidae - Wikipedia
Die Familie der Dalatiidae ist nicht nur weltweit sondern auch in allen Wasserschichten verbreitet und besteht aus achtzehn Gattungen mit rund siebzig Arten.
Die einzelnen Gattungen sind vom Äußeren recht unterschiedlich, zumal mit Ausnahme der Arten der Unterfamilie Etmopterinae die meisten Arten keine Dornen an der Rückenflosse besitzen.
Alle Dalatiidae sind ovovivipar, das heißt, die Embryonen schlüpfen bereits im Mutterleib aus ihren Eikapseln und entwickeln sich in der Gebärmutterregion bis zur Geburtsgrösse und werden dann lebend geboren.
