Endangered, Extinct, and Exotic Animals was a new trial event for both Division B and Division C in New York and Texas for the 2013 season, and is scheduled to be run as a trial event at the 2015 National Competition. Also known as Triple E or EEE, it tests competitors on their knowledge of endangered, extinct, and exotic animals. As well as identification, questions may be given on the causes and effects of changes in biodiversity and the effects the introduction of invasive species have on environments.


Event Overview

Competitors are expected to recognize all of the organisms on the official taxa list, which can be found on the second page of this document: [1]. Of these organisms, competitors are expected to know possible reasons as to why endangered and extinct animals reached their individual respective status, how introduced and invasive species were likely introduced to an area, and how their introduction could impact the area's biodiversity.

This event is given either in timed stations, as a test, or as a PowerPoint. Students are given either pictures or information for identification purposes and then asked questions about the specific organisms. Twenty 3”x5” index cards, with no published information or photographs, held together by a single ring, are the only materials allowed.

New York Version

For New York, questions will be limited to the species on the official New York List, which can be found on the second and third pages of these documents: Division B-[2] Division C-[3]. Each team is allowed one secure three ring binder with any information (from any sources).

Texas Version

In Texas, questions will be limited to the species on the official Texas List, which can be found on the third and fourth page of this document: Division B-[4]. Twenty-five 3”x5” index cards, with no published information or photographs, held together by a single ring, are the only materials allowed.

NOTE: All following species are from the National list.


Topeka Shiner (Notropis topeka)



The Topeka Shiner is a small minnow that lives in the prairie streams of the central United States. It is a shiny silver color and has a characteristic black colored stripe running along the side of its body. The states it lives in include Iowa, Kansas, Minnesota, Missouri, Montana, Nebraska, and South Dakota. The prairie streams it lives in are typically slow moving, have good water quality, and have a cool to moderate temperature. Instead of building their own nests, Topeka shiners share nests with orange-spotted or green sunfish. The main threat to these fish is changes to the water in which they live. Any activity, such as building projects, that increases silt is dangerous to the fish, as their food source and eggs can be buried.

Pallid Sturgeon (Scaphirhynchus albus)



The pallid sturgeon has a flattened snout, long tail, rows of bony plates, and grayish white back and sides, giving it a dinosaur-like appearance. They do not have teeth; instead, they suck up small fish and invertebrates from the river bottom. It can weigh up to 80 pounds and reach 6 feet in length. They live close to the bottoms of large, silty rivers such as the Missouri River, where they are now scarce. Males reach sexual maturity in 7-9 years, while females reach sexual maturity in 7-15 years. Pallid sturgeons are estimated to be able to live for up to 50 years. Reasons for their decline include channelizing of their river habitat, dams, and commercial fishing.

Paddlefish (Polyodon spathula)



Paddlefish are primitive fish that inhabit large, slow-moving, freshwater rivers such as the Mississippi River. They have been in North America since the Cretaceous Period (65 million years ago). Similarly to sharks, their skeleton is made of cartilage, not bone, and are characterized by a large, elongated rostrum. They are an average of 1.5 m long (4.9 ft), weigh up to 27 kg (60 lb), and can live at least 30 years. Paddlefish are filter feeders that mainly feed on plankton (planktivorous). The main reason of their decline is overfishing and habitat destruction, but they are also exploited for their eggs, which can be used to make caviar. Additionally, zebra mussel infestations can filter out all of the plankton, causing the fish to have a very limited diet.

Atlantic Bluefin Tuna (Thunnas thynnus)



The Atlantic Bluefin Tuna is one of the largest species of tuna, weighing up to 1500 pounds, reaching 10 feet in length, and living up to 30 years. Their body can be described as a spindle shape, with a pointed snout. The belly, sides, and cheeks are silvery, while the dorsal side is a dark blue. Although it can contain high levels of mercury and PCBs, the bluefin is prized in sushi for its high oil content. One of its unique adaptations is called a "concurrent exchanger": a type of blood vessel that allows this fish to maintain a body temperature that is higher than the ocean's. This allows it to move quickly, and is one reason why it is an apex predator. Its diet consists of fish like herring and anchovy, and sometimes cephalopods. The main reason for the bluefin's decline is overfishing, because of the high price it can fetch, and oil spills such as the Deepwater Horizon spill.

Sharks (Questions are about shark species as a whole and do not test on specific species)

Sharks are a group of fish in the class Chondrichthyes characterized by a cartilaginous skeleton, 5-7 gill slits, and pectoral fins not fused to the head. Most sharks, except those like the bull/river shark, live in seawater; the bull and river shark live in freshwater. They have dermal denticles (essentially small "teeth" on their skin) that prevent parasites and improve fluid dynamics. Sharks have teeth that are replaced throughout their lives. They have well developed senses of taste and smell. They are endangered mainly due to overfishing for commercial and recreational reasons, but are sometimes culled to "protect" humans.
