terrestrial Living on the ground
thorax The portion of the body between the head and abdomen of certain species that bears whatever legs and wings are present.
threatened The term is used in the 2000 IUCN Red List of Threatened Animals to refer collectively to species categorized as "Critically Endangered" (CR), "Endangered" (EN), "Vulnerable" (VU), "Low Risk" (LR), or "Data Deficient" (DD).
Tropical coastal -An aquatic biome including the ocean bottom in coastal areas of tropical regions, to about 1000 m depth.
Tropical deciduous forest -A terrestrial biome similar to tropical rainforest and found at the same latitudes, but rainy and dry seasons are more distinct and the total amount of rainfall is usually less. Most trees are deciduous and drop their leaves during the dry season. Thorny vegetation is sometimes prominent.
Tropical rainforest -A terrestrial biome found within 23.5° of the equator in areas where rainfall is abundant (more than 250 cm/year) and the dry season, if any, is brief. Forests are very diverse floristically and structurally; trees sometimes reach great heights. Most trees are evergreen; deciduous species, if present, do not all lose their leaves at the same time of year.
Tropical savanna and grassland -A terrestrial biome. Savannas are grasslands with scattered individual trees that do not form a closed canopy. Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia.
Tropical scrub forest -A terrestrial biome similar to tropical deciduous forest, but most trees are small, the dry season is prolonged, and many plant species bear thorns.
turtle (tûr' tl) - n. any reptile of the worldwide order of Testudines, comprising aquatic and terrestrial species having the trunk enclosed in a shell consisting of a dorsal carapace and a ventral plastron.
turtle exluder device A Turtle Excluder Device is a hatchdoor placed in a trawler net that allows sea turtles to escape while retaining the desired catch. TEDs are effective approximately 97% of the time. They are credited with saving thousands of sea turtle lives every year, and are critical to the survival of the Kemp's ridley turtle. TEDs are inexpensive to install (less than $500 US) and have benefits besides saving the lives of turtles, including reduced fuel consumption and decreased by-catch.
type locality The locality from which a species or subspecies was first described
