Category: RAINFOREST COSTA RICA


TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Amphibia
Order: Anura
Family: Dendrobatidae

Genus/species: Oophaga (formerly Dendrobates) pumilio

GENERAL CHARACTERISTICS: Despite the common name, coloration is reportedly highly variable among locations with up to 30 color morphs . Individuals may be ripe-strawberry red, brilliant blue, deep green or brown. The limbs are marbled dark blue and black. Body is slim, snout is rounded, the eyes large. The long, slender forelimbs end in finger and toe tips expanded into adhesive discs. Length to 2.5 cm (1 inch).

DISTRIBUTION/HABITAT: Nicaragua, Costa Rica, Panama. Primarily terrestrial in tropical rain forest leaf litter and decaying vegetation.

DIET IN THE WILD: Hunts diurnally, primarily upon ants and oribatid mites.

PREDATION: Night ground snakes are immune to the toxins of O. pumilio. Tadpoles are often consumed because their poison glands are underdeveloped.  They are in danger of an aggressive fungus – Chytrid Fungus – that is killing off frog populations around the globe.

REPRODUCTION: The male protects and keeps their eggs moist until they hatch. Then the female carries the tadpoles to a water filled bromeliad where the young feed on unfertilized eggs (oophagy).

CONSERVATION: IUCN Red List: Least Concern (LC)
population numbers are currently high despite illegal capture for the pet trade and habitat loss.

REMARKS: Alkaloids in the skin glands of poison frogs serve as a chemical defense against predation, and most come from the oribatid mites. In captivity, with a non-native food source, they lose their toxicity.

TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Amphibia
Order: Anura
Family: Dendrobatidae

Genus/species: Phyllobates lugubris

GENERAL CHARACTERISTICS: P. lugubris are small frogs, less than an inch in length, with the females slightly larger than the males. The head is longer than wide with a round snout. The back is jet black with paired dorsolateral stripes, of various colors including yellow, orange, gold or turquoise. They also have a thinner lighter turquoise or white ventrolateral stripe on each side from the tip of the snout to and along the front limbs.

 

DISTRIBUTION/HABITAT: This species inhabits the humid lowland and the premontane zone along the Atlantic coast of southeastern Nicaragua through Costa Rica to Central Panama. The frogs live in the leaf litter of the forest floor, near slow-moving water.

DIET IN THE WILD: Eat ants, mites, beetles, and spiders.

REPRODUCTION: Breeding occurs in the wet season. Males call to attract females, with a chortle that sounds like a hand rubbing an inflated balloon. A pair works together to create a ground nest in dry leaf litter. The female then deposits her eggs, which the male fertilizes. The male takes over and periodically moistens the eggs in the nest until the eggs hatch. He then carries 5 to 10 tadpoles at a time on his back to aquatic rearing sites. In about 2 months the tadpoles metamorphose into froglets that are about a half an inch long.

Phyllobates lugubris14933390504_dcd8c270b1_o

MORTALITY/LONGEVITY: Most poison dart frogs can live from 10 to 15 years in captivity. In general poison dart frogs have few predators. Their bright colors warn potential predators that they are toxic, even though in reality many of them merely taste bad because of sour but low potency toxins in their skins. Thus this group provides examples of both aposematic coloration and Batesian mimicry (an edible animal is protected by its resemblance to a noxious one that is avoided by predators).

CONSERVATION: IUCN Red List Least concern (LC) This species is relatively safe due to its wide distribution, tolerance to modification to its habitat, and its fairly large population. Some collected specimens have been found to be infected with Batrachochytrium dendrobatidis (chytrid fungus), but the pathogenic impacts are unclear.

REMARKS: Some South American natives capture other members of this genus (Phyllobates terribilis, P. bicolor, P. aurotaenia) to poison blow-gun darts. However, Phyllobates lugubris is not as toxic as other species in its genus and has not been documented to have been hunted primarily for its poison

P. lugubris is sympatric with another species, Eleutherodactylus gaigeae, known as the “false poison-dart frog.” This species mimics the appearance of P. lugubris in order to fend off predators, by having two paired red stripes running the length of the body. However, E. gaigae is a non-toxic mimic and does not produce batrachotoxins.

Remarks: Color communicates; deimatic behavior describes actions by an organism to startle a potential predator, thereby allowing the would-be prey to escape. An organism may display “eye spots”, which are often found on non-vital body parts like wings, flash bright colors, or arrange their body in an aggressive manner. Ref.

TAXONOMY
Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera (moths and butterflies)
Family: Nymphalidae (Brush-footed Butterflies)

Genus/species: Heliconius hewitsoni

GENERAL CHARACTERISTICS: A distinctive black butterfly with yellow transverse bands on fore- and hindwings. H. hewitsoni is very similar in general appearance to its Müllerian mimic H.pachinus. (Species with strong defences evolve to resemble one another and deter predation).

 

DISTRIBUTION/HABITAT: Found in the province of Chiriqui (Panama) and the Pacific slopes of Costa Rica. Usually individuals fly rapidly and in the canopy.

REMARKS: Heliconius are recognized by their large eyes, long antennae, characteristic elongate wing-shape, teardrop-shaped hindwing discal (disc-like) cell, and distinctive color patterns.

Adult butterflies systematically collect pollen from flowers, which they masticate on the proboscis to dissolve out amino acids. This allows caterpillars to develop relatively rapidly (since they do not need to store nutrients for egg and sperm production), and allows adults to have a greatly extended lifespan – up to 8 months – in the wild.

A second unusual trait found in some Heliconius species is a unique mating behaviour known as pupal-mating. Males of certain species search larval food plants for female pupae. The males then sit on the pupae a day before emergence, and mating occurs the next morning, before the female has completely closed (insect emerging from the pupa stage.)

Subfamily: Dynastinae (Rhinocerous Beetles)

Genus/species: Chalosoma caucasus

GENERAL CHARACTERISTICS: Males have large curved horns which are used when fighting other males for a female. The smaller females do not have horns but are covered with fine tiny hairs called setae. The male female differences are an example of sexual dimorphism.

It is the largest of the genus Chalcosoma and one of Asia’s largest beetles. Length up to 90–120 millimetres (3.5–4.7 in)

DISTRIBUTION: Found from Malaysia south into Indonesia

DIET IN THE WILD: Feed on compost from decaying logs and wood.

REPRODUCTION: Larvae emerge from eggs and grow through 3 instar stages, then a pupal stage in a papery covering (7.5 inches in length) followed by emergence of the beetle after several months

TAXONOMY
Kingdom: Animalia
Phylum: Arthropoda (insects, arachnids, and crustaceans)
Class: Insecta
Order: Blattodea (cockroaches and the termites)
Family: Blaberidae (giant cockroaches)

Genus/species: Blaberus giganteus 

GENERAL CHARACTERISTICS: They have three pairs of legs, and two pairs of wings, the forewings being light brown in colour. Largest neotropical cockroach by weight. A giant cockroach has a flattened, oval body, about 9 cm (3.5 inches) long and 4 cm (1.5 inches) wide. Females are slightly larger than males. They commonly run along the ground, although the adults have wings that are rarely if ever used for flight. They have long, very slender antennae and two sensory organs, called cerci, at the tip of the abdomen.

Blaberus giganteus 3445478500_7a02fcb067_b

DISTRIBUTION/HABITAT: Central and South America. They prefer dark, damp locations such as caves, rock crevices, tree hollows, and spaces under loose tree bark.

Blaberus giganteus 3775296951_fd8e873273_b

DIET IN THE WILD: Cockroaches are omnivores and detritivores. Common diet includes bat guano, rotting wood, fruit, seeds, decomposing vegetation, dead insects, and other animals. They help recycle decaying matter on the ground into useful nutrients for plants. 

REPRODUCTION: Females emit a pheromone that induces males to mate. Male courtship rituals include raising wings at right angles to abdomen and making trembling movements with abdomen. After mating, the female B. giganteus will be pregnant for life producing eggs which turn into nymphs which later become adults.

Blaberus giganteus 3779077163_a2d1b493c7_b-2

MORTALITY/LONGEVITY: They can live about 20 months as adults.

PREDATORS:  Army ants kill and eat nymphs.

CONSERVATION:  IUCN: Not Listed; CITES: Not Listed  

Cockroaches dates back over 200-300 million years, and are very adaptable and resilient animals.

REMARKS:  The leg bristles and antennae are used for seeing and feeling, in their dark habitat, while their flat bodies enable them to hide in crevices and underneath rocks. Cockroaches do not have lungs to breathe, but instead they take air in through spiracles, which are tiny holes on the sides of their bodies, and are used to send oxygen to other parts of the body. This allows the cockroach to survive for a period of time without its head, until it dies of infection, starvation or dehydration. When threatened, the giant cockroach is able to produce a foul smell to ward off predators.

TAXONOMY
Kingdom: Animalia
Phylum: Arthropoda
Class: Arachnida
Order: Araneae
Suborder: Araneomorphae (fangs slope towards each other in a pinching action)
Family: Nephilidae

Genus/species; Nephila Clavipes

GENERAL CHARACTERISTICS; Orb-weavers are highly sexually dimorphic. Females grow up to 8 cm (3 in), and are 5 to 6 times larger than males. Adults are mostly yellow with elongated abdomen and long, hairy legs. This spider lives in hot places. The long cylindrical abdomen of the spider may be angled towards the sun to reduce the amount of exposed body surface and thus prevent overheating. The reflective silvery surface of much of the body serves the same purpose.

Nephila Clavipes   5389185249_24cf049f4f_b 

DISTRIBUTION/HABITAT: These spiders are found from the southeastern United States south through Argentina and Peru. They prefer areas of high humidity and forest areas along trails and clearing edges. N. clavipes is the only member of its genus known in the Western Hemisphere.

DIET IN THE WILD: They feed on small flying insects: beetles, flies, moths, etc., that are captured in their web. After prey is entangled in the web, the spider incapacitates it by biting and then encases it in silk.

9129006757_d402137e70_h

REPRODUCTION: Mating is a tricky proposition for orb weaving males. For successful reproduction, males must successfully stimulate females in order to prevent being a meal for their would-be mate, though this unfortunate ending is relatively rare with this species.

MORTALITY/LONGEVITY: Life span: a single season (1 year).

REMARKS: 

•Orb weavers construct webs for defense and capture of prey.

•The silk of the web usually has a golden color that is visible to the naked eye and is the source of the common name.

•The impressive web of most orb weavers is a semi-permanent structure, repaired and rebuilt daily as necessary.

•Spiders from the Nephilia species on display from Madagascar are sometimes released into the Rainforest exhibit. They have settled in a territory behind the exhibit and observable from the spiral ramp. Only females are released as 1) they are much larger than the males and so more visible and 2) the Rainforest biologists have no interest in the uncontrolled breeding of these spiders in the exhibit!
