Title: Marbled electric ray
Content:  electric discharges by a length of 6.6 - 7.3 cm. The strength of the discharge increases by a magnitude of 105 over the course of gestation, reaching 47–55 volts by an embryonic length of 8.6 - 13 cm, close to that of an adult. Newborns measure approximately 10 - 14 cm long, and are immediately capable of performing characteristic predatory and defensive behaviors. Males mature sexually at approximately 21 - 29 cm long and five years of age, while females mature significantly larger and older at 31 - 39 cm long and twelve years of age. The maximum lifespan is 12–13 years for males and around 20 years for females.
Title: Lampsilis fasciola
Content:  The wavy-rayed lampmussel is a relatively small mussel distributed throughout Southern Ontario and the North-Eastern sections of the United States. The mussel is characterized by its yellow to yellowish-green colour. The mussel receives its name from the numerous thin wavy rays that cover its shell. These waves can be thin and separate or coalesced into significantly wider rays. The beak is slightly elevated above the hinge lines and the beak sculpture consists of 3 to 5 wavy lines. The shell is compressed to inflated (females) in shape and the anterior end is rounded with the posterior end bluntly pointed in males and rounded in females. The mussel's nacre is typically white or bluish, and the shell in general is rounded and generally symmetrical over the axis. The shell is mostly smooth, excepting certain wrinkles and growth rests that may appear. Wavy-rayed Lampmussles are typically less than 75 mm, but have been known to grow up to 90 to 100 mm in length.
Title: Lesser electric ray
Content:  This species of ray has a near-circular body and a short tail. It grows to approximately 45 cm long, and 20 cm wide, with colouration ranging from dark brown to reddish orange. It has irregular rings, sometimes oval in shape. The ventral surface ranges from white to greenish. It has tooth rows that vary in number from 17 to 34 in each jaw. This depends on the size of the specimen. It has two electric organs, elongate in shape, that run from the front of the eyes, down to the rear end of the disc. These organs can generate a peak voltage of about 14 to 37 volts, which they use to stun prey and to defend themselves.
Title: Blonde ray
Content:  Like all rays, the blonde ray has a flattened body with broad, wing-like pectoral fins. The body is kite-shaped with a short tail (hence the specific name brachyura, from Ancient Greek words meaning "short tail"). Maximum length is 120 cm.
Title: Christmas wrasse
Content:  the eye. The males in terminal phase have a body colour which is salmon-pink to orange towards the head, with 2 horizontal series of green rectangles with their long sides on the vertical with each fourth pair of the upper series extending to create a single green bar across the male's back. The head orange-brown in colour and has no bands and the tail is brownish to greenish, shading towards its margin to pink and having the rays in the last third coloured blue. This fish is similar to the surge wrasse (Thalassoma purpureum) but is distinguished from it by the spotted head of the females, the lack 'V-shaped' mark on the snout and in the males by the head colour. They can grow up to 30 cm in total length.
Title: Arctic lamprey
Content:  This lamprey is usually about 13 to 32 cm long, but specimens have been known to reach 63 cm and 200 g in weight. Non-anadromous individuals are rarely over 18 cm long. It is brown, gray, or olive in color with a paler belly. There are two dorsal fins located near the tail, the posterior one larger than the anterior. Males are larger than females. The caudal fin has two lobes, the lower longer than the upper. It is continuous with the dorsal and anal fins. The anal fin of the male takes the form of a small ridge.
Title: Marsha's lanternshark
Content:  Males reach a length of up to 23.4 cm, while females reach 19.2 cm. The species is slender and has a whitish and purplish body colouration. Between the pectoral and pelvic fins and the upper caudal fins are markings with a dark and light banding pattern.
Title: Six-line wrasse
Content:  The six-line wrasse is very small species of wrasse which attains a maximum total length of 10 cm. It is violet in colour and is marked with six orange stripes along the flanks. There is also a small eyespot on the dorsal part of the base of the caudal fin, a blue stripe along the base of the anal fin, and a blue streak on the pelvic fin. It has red eyes.
Title: Striated wrasse
Content:  The striated wrasse is a small species of wrasse with an overall reddish colour with 24 fine longitudinal white lines on its body and sometimes showing 5-6 dark horizontal bars. There is a blue streak below the eye and the gill cover has dark margins. It can grow to 9 cm in total length. The males and females show similar colourations and patterns but females tend to be less intensely coloured. The striated wrasse shows red fluorescence with the fluorescence being on the bony scales and fin rays.
Title: Warming's lantern fish
Content:  Warming's lantern fish grows to a length of about 8 cm. The rounded dorsal fin has 13 to 15 soft rays and the anal fin has a similar number of soft rays. The body has patches and scale-like specks of bioluminescent material.
