贝尔彻海蛇

The belcher’s sea snake is of moderate size, ranging from 0.5 to 1 meter (about 20–40 inches) in adult length. Its thin body is usually chrome yellowish in colour with dark greenish crossbands. The dorsal pattern does not extend onto the venter. The head is short and has bands of the same colours. Its mouth is very small but suitable for aquatic life. Its body, when viewed out of water, appears to have a faint yellow colour. Its scales are different from most other snakes in that they overlap each other. Each dorsal scale has a central tubercle. The body is strongly laterally compressed posteriorly. The ventral scales are very narrow, only slightly wider than the dorsal scales.

蓝环章鱼

The greater blue-ringed octopus is, despite its vernacular name, a small octopus whose size does not exceed 10 centimeters, arms included, for an average weight of 80 grams. Its common name comes from the relatively large size of its blue rings (7 to 8 millimeters in diameter), which are larger than those of other members of the genus and help to distinguish this type of octopus.The head is slightly flattened dorsoventrally and finished in a tip. Its eight arms are short.
