The greater siren (Siren lacertina) is an eel-like amphibian.

Some amphibians (e.g. the cane toad and greater siren) aestivate during the hot dry season by moving underground where it is cooler and more humid.

His zoological interests led Garden to write about cochineal insects and about the greater siren, (Sirena lacertina), once called the mud iguana.

The specific epithet intermedia denotes their intermediate size, between the greater siren, Siren lacertina, and the dwarf sirens, Pseudobranchus spp.

It is one of four amphisbaenians that have legs, and the only non-extinct species of animal to have only two limbs, apart from the Lesser and Greater Siren.

The specific epithet intermedia denotes their intermediate size, between the greater siren, Siren lacertina, and the dwarf sirens, Pseudobranchus spp.

The Architectural gear ratio is explained through the segmented muscle model 3 proposed by Emanuel Azizi, where a muscle segment is shown as a single muscle fiber attached to the myosepta of a Siren lacertina an aquatic salamander at a certain acute, pennation angle.

Panturichthys isognathus is an eel in the family Heterenchelyidae (mud eels).

The Heterenchelyidae or mud eels are a small family of eels native to the Atlantic, Mediterranean, and eastern Pacific.

Due to its wide distribution, lack of threats and lack of observed population declines, the IUCN redlist currently lists the Pacific mud eel as Least Concern.

Fishermen can expect to catch brown trout, rainbow trout, small mouth bass, bream, rock bass, crappie, catfish, white sucker and many other species as well as creek chubs, fresh water mussels and mud eels.

Mainstream and ethnic markets sell exotic species, from mud eels to green crabs, according to Walter Courtenay, a retired Florida Atlantic University biology professor who works as a volunteer fishery research biologist with the United States Geological Survey.
