What is the tiger shark’s population trend?
Decreasing
Given the wide range of the species and the localities of the shark control programs, the tiger shark is suspected to have globally undergone an overall population reduction over the past three generations (53- 68 years) based on actual levels of exploitation from commercial, recreational, and unregulated fisheries, as well as shark control programs. A further population reduction is suspected over the future three generation lengths (2018-2086) based on current levels of exploitation that are likely to continue into the future.

Tiger sharks are one of the ocean’s largest predators.
True
Tiger sharks are one of the largest ocean predators ranging from 3.25-7.5 m. (10.66-24.6 ft.) in length and 385-862 kg.
False

The tiger shark’s traversal replicates what letter?
S
In tiger sharks, the heterocercal tail, or caudal fin, is the primary source of propulsion. The caudal fin produces a downward thrust of water behind the center of balance in a shark, which should cause its head to turn upwards. However, because the tail also moves side to side, it keeps the head from turning upwards. Because of this, tiger sharks move in an S-shaped fashion.
