There are two recognized subspecies of tiger*: the continental ( Panthera tigris tigris) and the Sunda ( Panthera tigris sondaica). The largest of all the Asian big cats, tigers rely primarily on sight and sound rather than smell for hunting. They typically hunt alone and stalk prey. A tiger can consume more than 80 pounds of meat at one time. On average, tigers give birth to two to four cubs every two years. If all the cubs in one litter die, a second litter may be produced within five months. Goldsmith, O. (2010). A History of the Earth, And Animated Nature, Volume 2. Nabu Press. p.297.

Carabidae and Cicindelidae collected from January to December in 1985 by a number of different collecting methods in the Dumoga?Bone National Park area of N. Sulawesi (Indonesia) were examined to assess their reproductive seasonality. The state of gonad maturity was assessed through dissection of 5099 specimens, representing 203 species of Carabidae and 15 species of Cicindelidae. For the Carabidae, 45.7% of females and 12.0% of males were immature (non?reproductive). For the Cicindelidae the corresponding figures were 38.7% and 18.5%. In carabids the peak month for immatures is July and this corresponds with the highest percentage of females that are post?reproductive (as evidenced by the presence of the corpora lutea). A similar but less pronounced trend is found in male carabids. The proportion of immatures varies less in cicindelids during the year. Analysis of data for carabids from different habitats and lifestyles (leaf litter, dead wood and under bark, fossorial, riparian, grass/marsh, log?runners, leaf?runners, and termitophiles), suggests that different guilds have different patterns of reproductive seasonality. Furthermore, the reproductive seasonality may differ between species within these guilds. The effects on reproductive seasonality of the considerable local variation in climate in the study area and of sampling at different altitudes and with a range of collecting methods are also considered. 15 pp., 3 figs, 11 tabs, gr. 8.

The tiger's skull is similar to a lion's skull, with the frontal region usually less depressed or flattened, and a slightly longer postorbital region. The lion skull shows broader nasal openings. Due to the variation in skull sizes of the two species, the structure of the lower jaw is a reliable indicator for their identification. [19] The tiger has fairly stout teeth; its somewhat curved canines are the longest among living felids with a crown height of up to 90mm (3.5in). [23] Size a b Actman, Jani (24 February 2017).

The authors of the 2015 study noted that this two-subspecies reclassification will affect tiger conservation management. [14] It would make captive breeding programs and future re-wilding of zoo-born tigers easier, as one tiger population could then be used to bolster the population of another population. However, there is the risk that the loss of subspecies uniqueness could negatively impact protection efforts for specific populations. [15]
