In some primitive cartilaginous fishes, such as the spiny dogfish or mud shark ( Squalus acanthias ), there is a terminal nerve numbered zero, since it exits the brain before the traditionally designated first cranial nerve.

The spiny dogfish has the longest lifespan at more than 100 years.

For example, both the spiny dogfish and the Port Jackson shark have spines in their dorsal fins which are capable of secreting poison.

:* Squalidae ( dogfish sharks ), particularly the spiny dogfish ( Squalus acanthias )

Cephalopods, particularly squid, also form an important component of its diet, while smaller sharks such as spiny dogfish ( Squalus acanthias ) and tope sharks ( Galeorhinus galeus ) are rarely taken.

The spiny dogfish, spurdog, mud shark, or piked dogfish, Squalus acanthias, is one of the best known of the dogfish which are members of the family Squalidae in the order Squaliformes.

The spiny dogfish has dorsal spines, no anal fin, and white spot along its back.

A mountain of spiny dogfish.

In the recent past the European market for spiny dogfish has increased dramatically, which led to the overfishing and decline of the species.

This drastic increase led to the creation and implementation of many fishery management policies placing restrictions on the fishing of spiny dogfish.

In 2010, Greenpeace International added the spiny dogfish to its seafood red list.

This species feeds on a variety of benthic and pelagic bony fishes, including hake, flounders, rockfishes, lingcod, topsmelt, mackerel, and herring, and on cartilaginous fishes, including elephantfishes ( Callorhinchus ), spiny dogfish ( Squalus acanthias ), young bluntnose sixgill sharks ( Hexanchus griseus ), and ghost catshark ( Apristurus ) egg cases.

The dish can be one of many species of small shark, including the spiny dogfish ( Squalus acanthias ) or the bull huss ( Scyliorhinus stellaris ).

However, the spiny dogfish is now an endangered species due to overfishing, and is classed as Vulnerable on the IUCN Redlist and the North East Atlantic population as Critically Endangered.

A few species can creep very slowly by using spiny defensive zooids as legs.

These can trap enemies, who are defeated if the bubble is then burst by the player's spiny back.

During Sachet's visit in 1958, Clipperton's vegetation was found to consist of a sparse cover of spiny grass and low thickets, a creeping plant ( Ipomoea sp.

Mammals of Crete include the vulnerable Kri-kri, Capra Aegagrus Creticus that can be seen in the national park of the Samaria Gorge and on Thodorou, Dia and Agioi Pantes, ( islets off the north coast ), the Cretan wildcat and the Cretan spiny mouse.

The word cactus derives, through Latin, from the Ancient Greek ( kaktos ), a name originally used for a spiny plant whose identity is not certain.

The fruit is a spiny capsule 4 – 10 cm long and 2 – 6 cm broad, splitting open when ripe to release the numerous seeds.

Datura are usually planted annually from the seed produced in the spiny pods, but with care, plants can be overwintered.

Thorn forest, a dense forest of low stature with a high frequency of thorny or spiny species, is found where drought is prolonged, and especially where grazing animals are plentiful.

The western and southern sides, which lie in the rain shadow of the central highlands, are home to dry deciduous forests, spiny forests, and deserts and xeric shrublands.

The family Didiereaceae, composed of four genera and 11 species, is limited to the spiny forests of southwestern Madagascar.

* Medium spiny neurons, most neurons in the corpus striatum.

The dorsal and anal fins are divided into anterior spiny and posterior soft-rayed portions, which may be partially or completely separated.

A better etymology perhaps is from Latin sudis, plural sudes, " spines ", which can be used of spiny fish or spiny terrain.

The primary natural resources are spiny lobster, conch and other shellfish.

The trunk of the tree could also be represented by an upright caiman, whose skin evokes the tree's spiny trunk.

The 1961 volcanic eruption destroyed the Tristan da Cunha canned crayfish ( spiny lobster ) factory, which was rebuilt a short time later.

* Medium spiny neurons so called due to the presence of spines on the dendrites, and making up 96 % of the striatum.

The cortical pyramidal neurons projecting to the striatum are located in layers II-VI, but the most dense projections come from layer V. They end mainly on the spines of the spiny neurons.

While cortical axons synapse mainly on spine heads of spiny neurons, nigral axons synapse mainly on spine shafts.

Metabotropic dopamine receptors are present both on spiny neurons and on cortical axon terminals.

Leaves typically have sharp lobe tips, with spiny bristles at the lobe.

* Ctenoid scales have a toothed outer edge, and are usually found on fish with spiny fin rays, such as bass and crappie.
