Taxonomic Hierarchy
This is the kingdom that sharks belong to?
What is Animalia?
This shark order contains the bullhead sharks, including the family heterodontidae.
What is heterodontiformes?
Unlike bony fish, shark skeletons are made mostly of this flexible material.
What is cartilage?
These reproductive structures are found in male sharks but not females.
What are claspers?
As apex predators, sharks help control these populations.
What are prey populations?
Sharks belong to this phylum, which includes organisms with a notochord at some point in development.
What is chordata?
This order contains frilled and cow sharks.
What is haxanchiformes?
These tiny, tooth like scales protect shark skin and help reduce drag.
What are placoid scales?
In this reproductive strategy, eggs develop outside the mother and contain a yolk sac for nutrition.
What are oviparous reproduction?
Sharks help move nutrients through these systems.
What are marine food webs and ecosystems?
This subphylum identifies sharks as vertebrates.
What is Vertebrate?
This order contains mackerel sharks, including the family Lamnidae.
What is lamniformes?
This fin provides propulsion.
What is caudal fin?
In this type of live birth, embryos develop inside the mother and receive nutrition from the mother.
What is viviparous reproduction?
Sharks help maintain healthy and balanced marine versions of these.
What are habitats?
Sharks are members of this class.
What is Chondrichthyes?
This order includes whale sharks, nurse sharks, zebra sharks, bamboo sharks and wobbegongs?
What are orectolobiformes?
This large organ is filled with oil and helps provide buoyancy.
What is the liver?
In this type of live birth, embryos develop inside the mother but receive neutron from the yolk.
What is ovoviviparous reproduction?
The presence of sharks can influence the behavior and distribution of other species through these.
What are trophic cascades?
This is the subclass listed for sharks in today's presentation.
This is the largest and most diverse shark order, containing cat shark, hammerheads, requiem sharks, and houndsharks.
What is carcharhiniformes?
These are the six main senses listed in today's presentation: sight, hearing, smell, touch, and this.
What are electroreception and the lateral line?
Certain shark species eat their unborn siblings and unfertilized eggs while still inside the mother.
What is intrauterine cannibalism?
This ecological role involves sharks controlling prey populations and helping keep food webs balanced.
What are apex predators?
