They like to eat fish and amphibians. This snake mates from late May to early June by forming “mating balls” consisting of one female and several males. They are live births, not hatched in eggs and have an average litter size of four up to ninety-nine but average about thirty babies. Only fifteen percent of the young survive their first year. They grow quickly, but then slow down when they approach sexual maturity, which is about two to three years.
There are also quite a few that are between 15mm and 19.99mm but not many that are longer. In comparison, the planehead filefish samples have a high frequency of individuals over a wider range of length, from 10mm to 34.99mm. The blue runner had a large number of individuals “hatched” between 6/22 and 7/2, and the planehead filefish samples were hatched over a longer period of time. Blue runner has a higher frequency of individuals between 13 and 23 days old with only a few older and none younger, while planehead filefish have a moderate frequency of individuals that range from 8 to 35 days old with only a few older and none
Crayfish, also called crawfish and crawdad, are lobster or shrimp like crustaceans that mainly live in freshwater. They are much smaller than a normal lobster, usually growing to around 3-4.5 inches long (Ball). They live for around 2 years. Overall, crayfish are a pretty resilient species. They have a pretty wide toleration for the water that they live in, even though they prefer a cooler more alkaline water in the in the 7.5-8.5 range with temperatures between 65-77 F(Ball).

Their image as a selective eater is only a legend. Rainbows are not quite as piscivorous or aggressive as brown trout or lake trout (char). Young rainbows survive on insects, fish eggs, smaller fish (up to 1/3 of their length), along with crayfish and other crustaceans. As they grow, though, the proportion of fish increases in most all populations. Some lake dwelling lines may become planktonic feeders.
This helps with buoyancy and balance. When they breathe-only through their nostrils, they can exchange 90% of the air in their lungs with each breath, compared to a human who only exchanges about 10% of their air. They may need to breathe every 30 seconds during strenuous activity but can stay submerged for up to 20 minutes. Their muscles lack the density of myoglobin (muscle hemoglobin) that is typical of other diving mammals. This trait contributes to their relatively short (8-15 minute) and shallow (10-20 feet) dives compared to seals and dolphins, however they do swim like dolphins and seals in a dorsoventral fashion as opposed to side to

1- Condylactis Anemone (Condylactis gigantean): The Condy Anemone is also known as the Haitian Anemone or Giant Golden Anemone. It is found throughout the Caribbean and Western Atlantic, in lagoons or on inner reefs, as individuals, or loose groups. It is never found in connected clusters. Its disc diameter is of 16" (40 cm), but a disc of about 4" (10 cm) is common in an aquarium. This species has diverse color variations.

They feed primarily on salmon and travel in pods of 15-30 individuals. The pods are matriarchal and it is typical for the offspring to spend their entire lives with their mothers. The dorsal fins of residents are rounded with a sharp angle on the trailing edge. (Ford, Ellis, & Balcomb, 1994) Transient Pods Transient orcas travel in much smaller groups; a pod usually has no more than 5-7 individual members. The home range of transients is much harder to define than that of the residents.
