Smooth coated otter - Head and body to 75cm, tail to 45cm. Long body and a long tail, covered in short sleek fur. It has short limbs with webbed 'fingers' and prominent claws. The upperparts are greyish brown and the underside is buffy.

Smooth-coated otters are generally social and live in pairs or family groups of parents and their young. They are active both during the day and at night.

Malayan water monitor - 2.5-3m long. Among the largest lizards in the world, certainly the largest reptile in our marine habitats. A robust, muscular body with a long tail that is flattened towards the slender tip. It has a slender forked tongue. The nostrils are located close to the tip of the long and slender snout. It has small non-overlapping scales on a thick leathery skin. Hatchlings are black with whitish undersides with rows of bright yellow spots forming bands along the back and tail. This pattern fades in adults which is often plain grey. Non-venomous and shy of humans, it will prefer to flee than to fight. But if cornered, it may bite. So do leave the monitors alone.

Strawberry slug - To about 1cm or smaller. Short, soft body with lots of short finger-like projections (cerata) that are transparent at the tips and filled with green stuff. Some have black spots, others with white stripes on the cerata. Tiny black eyes close together between the pair of long rhinophores. No oral tentacles.

Common Sea Star - Adults diameter with arms to about 12-15cm. Smaller juveniles are rarely seen. Body somewhat rounded (not flat). Arms long and tapered to a sharp tip, and edged with short flat, blunt spines. Most have five arms, but those with three, four and six arms are sometimes also seen.The underside is pale, with large tube feet tipped with suckers. Colours and patterns on the upperside are highly variable in shades of greyish blue, to brown and beige.

Margin in three colours: thin white line on the outermost edge, a transparent greyish band in the middle and orange band innermost next to black body. Centre of the body is raised, with a short grey or white stripe on the head. Underside uniformly semi-translucent grey with fine white margin. It has a pair of erect pseudotentacles at the front made up of folded edges of the body but lacks the marginal banding found in the rest of the body. The pseudotentacles are all black with white tips.
