Both species of anoa have been classified as endangered since the 1960s, and the population continues to decrease.

Both species will kill each other's pups, given the opportunity.

Both the number of base pairs and the number of genes vary widely from one species to another, and there is only a rough correlation between the two ( an observation known as the C-value paradox ).

Both species are smaller than the spotted hyena but larger than the aardwolf.

Both males and females grow to an adult length of to from snout to vent, with a total length of to making it the third largest aquatic salamander species in the world ( next to the Chinese giant salamander and the Japanese giant salamander ) and the largest in North America.

Both species, C. a. alleganiensis and C. a. bishopi undergo a metamorphosis after around a year and a half of life.

Both species have much grey in their wings in males, which does not occur in the Common Kestrel or its close living relatives but does in almost all other falcons.

Both species had their genomes sequenced and they appear to have diverged around 400, 000 years ago.

Both orangutan species are considered to be Endangered with the Sumatran orangutan being Critically Endangered.

Both species have very long ( approximately 35 centimetres ), flexible, blue tongues that they use to strip leaves and buds from trees.

Both size classes lived along side each other, and while researchers had previously suggested that they represent different species, Christopher Bennett showed that the differences between them are consistent with the concept that they represent females and males, and that Pteranodon species were sexually dimorphic.

Both species show extreme sexual dimorphism, possibly the largest of any mammal, with southern males typically five to six times heavier than the females.

Both species became extinct before the last glaciation.

Both species were larger than the modern hippopotamus, averaging about 1 meter ( 3. 3 feet ) longer.

* Both codes consider the first part of the two-part name for a species to be the " genus name ".

Both subgenus Magnolia and subgenus Yulania include species of major horticultural importance, and a change of name would be very undesirable for many people, especially in the horticultural branch.

Both species and hybrid rhododendrons ( including azaleas ) are used extensively as ornamental plants in landscaping in many parts of the world, and many species and cultivars are grown commercially for the nursery trade.

Both oviparous and ovoviviparous, as well as genuinely viviparous, species exist, although the Peripatopsidae essentially lack a placenta.

Both are typified by many grass species.

Both species are coded as thin wispy cirrus ( C < sub > H </ sub > 1 ).

Both species can grow to 3 ft 6 in ( 1. 07 m ) and can weigh up to 46 lb ( 21 kg ).

Both these species occur in a normal, a black and a rare white morph, confirming the view that simply dividing into species based on morph ( as had been done earlier ) is incorrect.

Both the Spring and Strawberry are excellent float streams, with the added bonus of rainbow trout and walleye in Spring River, and the smallmouth bass, crappie and bream in the Strawberry River.

Both species of crappie have a terminal mouth with many small conical teeth.

Both envisaged that spontaneous generation produced simple forms of life that progressively developed greater complexity, adapting to the environment by inheriting changes in adults caused by use or disuse.

Both male and female adults blood-feed, and they mate off the host.

Both nymphs and adults have a prominent capitulum ( head ) which projects forwards from the animal's body ; in the Argasidae, conversely, the capitulum is concealed beneath the body.

Both nestlings and adults engage in bill-clattering during the nesting season as a means of communication.

Both adults incubate the eggs and feed the chicks.

Both nymphs and adults have long paired cerci projecting from the tip of their abdomens.

Both adults have crested heads.

Both adults have a white ear-patch.

Statler and Waldorf also appeared ( as adults ) in the Saturday morning animated television series Jim Henson's Muppet Babies Both characters were voiced by Dave Coulier.

Both of Chaney's parents were deaf, and as a child of deaf adults Chaney became skilled in pantomime.

Both adults and calves have been observed to chase and catch fish and the adults may be teaching the calves how to hunt.

Both of these were aimed at teenagers and young adults.

Both adults and larvae feed on foliage and may skeletonize the crop.

Both larvae and adults are taken, and the fish will eat whatever local insect life is abundant at the time.

Both adults and larvae must consume adult feces which have been further digested by microflora for a time ; an arrangement that might be described as a sort of external rumen.

Both older and younger adults process emotional data over neural data.

Both adults lose 36 – 40 % of their body weight during this period.

Both adults and larvae are found in fast-moving water, feeding on algae and wood.

Both adults and larvae are aquatic, and are commonly found around plants.

Both contain areas designed exclusively for various age groups, including children, teenagers, and adults.

Both adults and larvae are predators, but will also scavenge dead insects.

Both the juvenile newts and the adults ( outside the breeding season ) live in terrestrial habitats with dense cover, such as scrub, rough grass and woodland, usually within about 200 metres of the breeding pond.

Both adults and larvae feed on raw skins and hides.
