The leopard frog is called that because it is spotted, like a leopard. This was once the most widespread frog species in North America. But since the 1960s, its population here and throughout the United States has declined.
They’re somewhat timid and do not like being held much, hiding below the water when they feel threatened. They are harmless to humans and do not produce toxins.
In 2006, a coalition of conservationists formally petitioned the Service to protect the western leopard frog and its habitat in the western United States under the Endangered Species Act. … “Yet, today, the frog itself is severely endangered by a combination of habitat destruction, pollution, and invasive species.”
Their range is most of northern North America, except on the Pacific Coast. They generally live near ponds and marshes, but will often venture into well-covered grasslands as well, earning them their other common name, the meadow frog.
The Pickerel frog is a relatively large frog that is often confused with the Northern Leopard Frog (Rana pipiens). However, the Pickerel frog has chocolate-brown spots arranged in two rows between the dorsolateral folds while the Leopard frog’s spots are more irregular and scattered.
Because frogs have no teeth, they swallow their prey whole. … Healthy backyard pond fish like koi, goldfish, and orfe don’t have too many worries from frog predation and the mixing of these species is generally compatible; with some interesting interactions from time to time, like frogs “riding” on the back of large koi!
|Length:||Adults from 2 to 4.5 inches|
|Lifespan:||2 to 4 years|
|Feed:||Adult frogs consume small invertebrates. Larvae eat algae, plant tissue, organic debris, and probably small invertebrates|
Leopard Frog Behavior
They do have parental care, as the offspring are briefly cared for by the females before going off on their own. These frogs are nocturnal, semi-aquatic, and hibernate in the winter, when they may stop eating for as long as three months!
Frogs usually make the calls around bodies of water that are suitable for breeding and egg laying. These calls can be heard during the evening and at night, and sometimes during daylight at the peak of the breeding season.
Male leopard frogs are presumably not territorial (Hunter et al. 1999). They gather together in dense groups in shallow water and actively seek the females. Coupling is by pectoral amplexus, which lasts for about 24 hours or less.
Leopard frogs are fierce hunters, but they must go for size-appropriate prey. Most juveniles stick to insects, spiders, earthworms and other easy prey such as slugs and snails.
The northern leopard frog (Rana [Lithobates] pipiens] has undergone significant declines particularly in the western United States and Canada. Leopard frog population losses in Nevada are largely due to habitat fragmentation and the introduction of nonnative fish, amphibian, and plant species.
The northern leopard frog sometimes lets out a screaming call when it is captured or startled.
Frogs are said to have two lives because they begin their lives in a completely different form than they end them.
Frogs and toads are cold-blooded, so their body temperatures take on the temperature of the environment around them. … Aquatic frogs, like our own southern leopard frog (Rana pipiens), usually spend the winter at the bottom of a pond or other body of water.
Least Concern (Population stable)
Are pickerel frogs poisonous to dogs? No. Even though pickerels secrete toxic substances that might kill a few predators, their secretion is not harmful to dogs.
Answer. Amphibians tend to return to the same pond each year – it’s likely there used to be a pond present which the animals are looking for. Amphibians migrate to ponds in spring, often returning to areas where they spawned in previous years.
