Coenobita Clypeatus
The Caribbean hermit crab (''Coenobita clypeatus''), also known as the soldier crab, West Atlantic crab, tree crab, or purple pincher (due to the distinctive purple claw), is a species of land hermit crab native to the west Atlantic, Belize, southern Florida, Venezuela, and the West Indies. Description Adults burrow and hide under the roots of large trees, and can be found a considerable distance inland. As with other terrestrial crabs, they use modified gills to breathe air. Their shells help maintain the humidity necessary for gas exchange to function. Typically, the Caribbean hermit crab's left claw is larger in size than its right claw and is purple in color. Female land hermit crabs release fertilized eggs into the ocean. The spawning (called "washing" in the English-speaking Caribbean) occurs on certain nights, usually around August. Ecology Caribbean hermit crabs are both herbivorous and scavengers. In the wild, ''C. clypeatus'' feeds on animal and plant remains, overr ...

Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

Arthropods Of The Dominican Republic
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior organs; it has an open circulatory system. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. Their nervous system is "ladde ...

Fauna Of The Caribbean
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used by ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hermit Crabs
Hermit crabs are anomuran decapod crustaceans of the superfamily Paguroidea that have adapted to occupy empty scavenged mollusc shells to protect their fragile exoskeletons. There are over 800 species of hermit crab, most of which possess an asymmetric abdomen concealed by a snug-fitting shell. Hermit crabs' soft (non-calcified) abdominal exoskeleton means they must occupy shelter produced by other organisms or risk being defenseless. The strong association between hermit crabs and their shelters has significantly influenced their biology. Almost 800 species carry mobile shelters (most often calcified snail shells); this protective mobility contributes to the diversity and multitude of crustaceans found in almost all marine environments. In most species, development involves metamorphosis from symmetric, free-swimming larvae to morphologically asymmetric, benthic-dwelling, shell-seeking crabs. Such physiological and behavioral extremes facilitate a transition to a sheltered ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ecuadorian Hermit Crab
The Ecuadorian hermit crab (''Coenobita compressus'') also known as the Pacific hermit crab is a species of land hermit crab. It is one of the two land hermit crabs commonly sold in North America as pets, the other being the Caribbean hermit crab (''C. clypeatus'').Audrey PaviaHermit CrabPG.18' Retrieved July, 2009Barren'sHermit Crabs PG.9' Features and identification ''Coenobita compressus'' is a member of the phylum Arthropoda and the class Malacostraca. They can be up to in length and are thought to be one of the smallest species of land hermit crabs. They have four walking legs, a small pincer, a large pincer, and antennae. Many people who keep these hermit crabs as pets notice that Ecuadorian crabs can be relatively fast walkers, even faster than Caribbean hermit crabs, and that they are quite active. Their eyes are more oval-shaped when compared to the round eyes of Caribbean hermit crabs and are thicker. Their big claw has four or five small ridges on the upper part. The ...

Predator
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and i ...

Cittarium Pica
''Cittarium pica'', common name the West Indian top shell or magpie shell, is a species of large edible sea snail, a marine gastropod mollusk in the family Tegulidae. This species has a large black and white shell. This snail is known as "wilk" or "wilks" (or sometimes as "whelks") in the English-speaking Caribbean islands of the West Indies, where this is a popular food item. The word "will" or "wilks" can be used both as a singular form and a plural. This species is however not at all closely related to the species that are known as whelks in the U.S. and in Europe. In some Spanish-speaking parts of the Caribbean, when used as a food source ''Cittarium pica'' is known as ''bulgao'', or simply as ''caracoles'' (snails, in Spanish). In Venezuela it is called ''quigua''; in Cuba it is called ''cigua''. ''Cittarium pica'' is considered the third most economically important invertebrate species in the Caribbean, after the spiny lobster (''Panulirus argus'') and the queen conch ('' ...

Mona Ground Iguana
The Mona ground iguana (''Cyclura stejnegeri'') is a rock iguana that is endemic to Mona Island, Puerto Rico, and is the largest native terrestrial lizard in Puerto Rico. It was previously considered a subspecies of the rhinoceros iguana (''Cyclura cornuta''). Taxonomy The Mona ground iguana belongs to the genus ''Cyclura''. It was named by Thomas Barbour and Gladwyn Kingsley Noble as a species in 1916. In 1937, Thomas Barbour considered it to be a subspecies of ''Cyclura cornuta'', although he doubted it was particularly distinct. He was followed for the next 60 years. Research into scalation patterns in 1977 found little difference between this taxon and the nominotypical subspecies, but markedly more differences in subspecies ''onchiopsis'', and thus found Barbour's 1937 taxonomic interpretation best approximated the obvious relatedness of these taxa. Its specific name, ''stejnegeri'' honors Leonhard Hess Stejneger, who, when writing his ''Herpetology of Porto Rico'' in 1902, ...

Zootaxa
''Zootaxa'' is a peer-reviewed scientific mega journal for animal taxonomists. It is published by Magnolia Press (Auckland, New Zealand). The journal was established by Zhi-Qiang Zhang in 2001 and new issues are published multiple times a week. From 2001 to 2020, more than 60,000 new species have been described in the journal accounting for around 25% of all new taxa indexed in The Zoological Record in the last few years. Print and online versions are available. Temporary suspension from JCR The journal exhibited high levels of self-citation and its journal impact factor of 2019 was suspended from ''Journal Citation Reports'' in 2020, a sanction which hit 34 journals in total. Biologist Ross Mounce noted that high levels of self-citation may be inevitable for a journal which publishes a large share of new species classification. Later that year this decision was reversed and it was admitted that levels of self-citation are appropriate considering the large proportion of papers f ...
