TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order:Perciformes (Perch-likes)
Family: Pomacentridae (Damselfishes, Chromis, Aneomonefishes)
Subfamily: Amphiprioninae (anemonefishes)

Genus/species: Amphiprion ocellaris

GENERAL CHARACTERISTICS: Adults are orange with three broad vertical white bands with thin black margins. Females are larger than males. Similar to the Clown Anemonefish (Amphiprion percula) but has 11 spines in the dorsal fin compared to 10, while the spiny part of the dorsal fin is also taller.

Length up to 9 cm (3.5 inches)

DISTRIBUTION/HABITAT: Found among tropical Pacific Ocean coral reefs. They sleep and feed among the tentacles of their host anemone. Stichodactyla gigantea, Stichodactyla mertensi, as well as the anemone Heteractis magnifica and others. The False Clownfish is usually found at depths of about 15 m (50 ft).

(Amphiprion ocellaris) aka FALSE CLOWNFISH

DIET IN THE WILD: Feeds primarily on zooplankton, especially copepods and also on filamentous algae.

REPRODUCTION: A. ocellaris breeds continuously at the Steinhart. Adhesive eggs are laid on a patch of cleared rock near the host anemone’s base and guarded by the male. Eggs hatch after 10 days. The tiny transparent planktonic larvae swim away from the anemone. Two weeks later the larvae metamorphose into small fish. As protandrous hermaphrodites; all individuals mature as males, and all females are sex-reversed males. In the absence of a female the largest male will turn into a female.

Longevity: Up to 12 years in captivity

REMARKS:  Clownfish and anemone display a classic case of mutualism. Clownfish become resistant to their host by gradually (matter of minutes to days) acquiring a covering of mucus
by brushing against the tentacles of their host. Once the fish has become chemosensorilly camouflaged, the host anemone’s nematocysts do not sting the clownfish.

Some of the anemone’s nutrition results from the clownfish’s activities; clownfish gain protection among the anemone’s nematocysts.

Nemo and his parents in Finding Nemo resemble this species. That said, Marlin, Nemo’s father, given the scenario would have changed into a female following the death of Nemo’s mother and remained near his host anemone, rather than swimming to Sydney. But then the film makers wouldn’t have a narrative to support this film! The name “Nemo” has found its way into FishBase (http://www.fishbase.org) as a common name for this species in the USA!

TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Perciformes
Family: Cichlidae
Tribe: Lamprologini

Genus/species: Neolamprologus species

Male Neolamprologus brevis for example reach lengths of just 4.5 cm (1.75 inches) while females are even smaller, around 3 cm (1.25 inches) long. These cichlids probably evolved from fish that lived in rocky cave, but pressure from competition and the many predators of Lake

Lake Tanganyika has very high levels of carbonate hardness, and the calcium in the water ensures that empty shells dissolve much more slowly than they do in most rivers and lakes. In some places there are piles of shells more than 3 metres (10 feet) deep.

DIET IN THE WILD: Zooplankton and small invertebrates

REPRODUCTION: To protect their young eggs are laid by the female within a shell and fertilized as she lays them or immediately after by the male.The female protect the eggs within the shell by fanning her pectoral fins to keep the internal water oxygenated, and often rearranging the substrate to create barriers or to hide the shell from predators.

The eggs hatch within 48 hours, and the yolk sac is absorbed within five days. Fry typically emerge from the shell a week after spawning and they remain benthic for days or weeks after their emergence.

Genus/species: Thalassoma hardwicke

Sixbar Wrasse8410603333_678203e399_b

GENERAL CHARACTERISTICS: Adult is pastel blue to pale green with six dark, vertical bars on their body, the last two saddling the tail. The head has a distinct ‘daisy’ print around the eyes made of a few different pastel colors (e.g., pink bands radiating from the eye) in larger adults.  Max length: 20 cm (7.9 in).

DISTRIBUTION/HABITAT: Found in the tropical Indo-Pacific in shallow lagoons and seaward reefs. Depth to 15 m (50 ft.).

DIET IN THE WILD: Carnivore on benthic and planktonic crustaceans, invertebrates and small fishes.

Sixbar Wrasse8393609669_e1f3601c7c_b

REPRODUCTION: Protogynous hermaphrodite; Hermaphroditism occurs when a given individual in a species possesses both male and female reproductive organs, or can alternate between possessing first one, and then the other. The most common pattern is for a female to change into a male (protogyny). This often happens when a large dominant male is removed by a predator. Within a few days, the largest female in the harem becomes a dominant male and takes over the missing male’s function. This pattern is common in coral reef fishes, such as parrotfishes, wrasses, and groupers.
T.hardwicke is a pelagic spawner meaning water currents widely disperse the young. The eggs, embryos and larvae of pelagic spawners contain oil globules or have a high water content. As a result, they are buoyant and are widely dispersed by currents. The downside is that mortality is high, because they can be eaten so easily by pelagic predators. Pelagic spawners who live in or around coral reefs can spawn a small number of eggs almost daily over a period of months.

CONSERVATION: IUCN; least concern

REMARKS. Occur in small, loose groups.

8274421702_51193cf844_b

GENERAL CHARACTERISTICS: Said to be the third largest spider in the world, this is a large-bodied tarantula with abdomen and legs covered with sensitive, long, and partially pink or salmon-colored hairs. Maximum size: body, 9-10 cm (3.5–4 in); leg span, 20-25 cm (8–10 in).

DISTRIBUTION/ HABITAT: Throughout northeastern Brazil on the tropical forest floor

DIET IN THE WILD: Lie and wait carnivore, eating large crawling insects and other invertebrates, small rodents, lizards, and frogs rarely seen eating birds like newly hatched chicks of ground-dwelling birds. Venom injected by chelicerae that liquefy the kill, which is then sucked in by the mouthparts.
Regardless of its name, the spider is rarely seen eating birds.

REPRODUCTION: The male spins a small area of silk onto which he deposits his sperm. The sperm is then absorbed into the pedipalps, which during mating are inserted into the genital opening of the female, transferring the sperm, which remains viable. After insemination, the male makes a swift retreat as the much smaller males occasionally become a sacrifice to the female’s need to maintain the nutritional viability of a mother-to-be. The female lays up to 2000 fertilized eggs in a thick, silken sac which she guards fiercely. Young spiderlings are born about 3 weeks later. Voracious feeders, they grow quickly.

PREDATORS: Tarantulas have few enemies except the tarantula hawk wasps. Members of this wasp family use their sting to paralyze species specific tarantulas.

REMARKS: Like most tarantulas and some other spiders, if this spider loses one of its legs, it can regrow the lost appendage.
While not highly aggressive and bites are not fatal to humans (most tarantula bites are similar to a bee sting in toxicity), this big bruiser, because of its long fangs, can inflict a serious wound which one researcher defined as “capable of medically significant mechanical damage”! If pursued by a potential foe, the spider rubs its legs against its abdomen, throwing tiny, barbed hairs that become imbedded in the attacker. The barbs can cause significant irritation, especially if lodged in the eyes or nasal passages.
Venomous

Genus/species: Chrysaora Pacifica

IMG_5334

GENERAL CHARACTERISTICS: APPEARANCE: Bells can grow up to 12 inches across and tentacles can stretch 10 feet or more. Their bells are white with brown-to-orange stripes, containing up to 32 very long orange-red tentacles and four long lips. One of C. Pacifica’s most distinguishing characteristics can be found on their undersides, where they have 16 brown stripes and eight stomach pouches.

DISTRIBUTION/ HABITAT: Deep open waters of the northern Pacific Ocean, Arctic Ocean and the Bering Sea. Found at the ocean surface to 200 meters (650 feet) below the surface.

DIET IN THE WILD: Other jellies, small crustaceans called copepods, and small fishes.

REPRODUCTION and DEVELOPMENT: The life cycle made up of five stages. They go through a metamorphosis or change in shape as they grow.
1.lifecycle begins when males broadcast or release sperm into the water and the females catch the sperm to fertilize the eggs she has produced and is holding in her mouth.
2. The fertilized eggs remain attached to the mother’s oral arms and grow into a flat jelly bean-shaped planula.
3. The planula then grows into flower-shaped polyps and the mother releases them into the ocean.
4. The polyps attach to a solid surface and undergo asexual reproduction through which they make an exact copy of themselves without eggs and sperm. The polyp makes these identical animals by budding where the new polyp grows out of its side.
5.After the new polyp is fully formed, it is released into the ocean and starts to change shape, looking more like the adult nettle. The nettle develops a bell, arms and tentacles until it is a fully formed medusa or adult. (Shedd AQ).

REMARKS: Like many jellies, Japanese sea nettles use stinging cells to defend themselves and stun their prey. While not especially poisonous, their stings can cause intense skin irritation and burning sensations in humans. Some people can have allergic reactions to their venom. If you see one in the water, stay away because there’s a good chance more of them are nearby. Japanese sea nettles travel in swarms, which increases your chance of being stung if you encounter one.

Genus/species: Meiacanthus grammistes

8393608989_a6c74ab647_b

GENERAL CHARACTERISTICS: Deep-bodied with a pointed snout and long continues dorsal fin. It is brown with tan wavy bands stretches the length of its body. On the dorsal fin near the head is a small blue spot. It grows to a size of 10 cm (4 inches) in length. Lined pattern on the body that ends in spots on the tail-fin base.

DISTRIBUTION/HABITAT: Western Pacific and Eastern Atlantic Ocean in sheltered lagoons and seaward reefs.

DIET IN THE WILD: DIET IN THE WILD: Omnivorous; small invertebrates and plant material. Remarks: About 50 blenny spp., including the 22 Meiacanthus spp., have evolved glands that produce venom and fangs to deliver it. The fangs are very large canines in the lower jaw that are grooved to inject venom when the fish bites, usually only in self-defense. Reports indicate that the fang blenny will bite the inside of a predator’s mouth and is quickly spit out.
